Why development of German OSM Carto style is currently stuck.

I am the Maintainer of the German Style OSM Carto fork and operator of http://tile.openstreetmap.de for a couple of years now. Usually I try to follow upstream releases as fast as possible to make sure that the fork keeps as close to upstream as possible.

However, back in March OSM Carto v5.0.0 has been released which requires a reimport of the osm2pgsql database. As doing this is a lot of work for my small two-server setup maintained by a single person I decided to combine this reimport with a new Approach for map localization I have been thinking about for some time. The code is designed for the new osm2pgsql Flex Backend introduced by Jochen Topf in February. Unfortunately I did not look closely enough at the Flex Backends documentation. I missed the fact, that the get_bbox()function is currently not available on relations which would force me to disable localization for relations. I decided against doing this for now in the hope that Jochen will add this missing feature to his code soon. If this situation will persist till the end of the year I will likely have to think about another solution, but for now we will unfortunately just have to wait.

How did you contribute – celebrated its 10th birthday 1 | © Pascal Neis | Map data © OpenStreetMap contributors

Mapping

  • Alex started a discussion on what to consider when mapping a street’s width and the different variants currently used. In the discussion, Tobias Zwick, from StreetComplete, referred to a helpful app for measuring with your phone and the help of augmented reality.
  • After the approval of amenity=funeral_hall, user Vollis is proposing the subtag funeral_hall=*, for a building or room used for funeral ceremonies ancillary to a funeral director’s shop or a crematorium.
  • Andrew Wiseman, from Apple, has updated (es) > en the challenges on MapRoulette for Bolivia using new data. The challenges can be found here.
  • Michael Montani, from the UN Department of Operational Support, invited (fr) > en OSM contributors, on various African local discussion lists, to help support UN missions. Mappers can do this by participating in the Tasking Manager jobs they have created to map highways, waterways, land cover, land use, places, and any other relevant points of interest.
  • User stragu warned users of OsmAnd Maps for iOS about a bug that shifts POIs without notice, due to incorrect rounding of coordinates. The issue affects versions 3.10 to 3.14, but was promptly addressed and is solved in version 3.80.

Community

  • After a long break, the Belgian community continues its choice of the ‘Mapper of the Month’. This month it is Jacques Fondaire, aka jfonda, from Belgium.
  • [1] The widely-used tool ‘How did you contribute to OpenStreetMap’ celebrated its 10th anniversary – we congratulate and say thank you, Pascal Neis, for this and also for all the other nice stats you have added over the years!
  • The 35th edition of the Geomob Podcast features an interview with Sarah Hoffmann who, as a software developer, is responsible for the maintenance of Nominatim, the most important software for geocoding used by OpenStreetMap. Sarah explains the technical aspects and challenges of managing a technically complex and publicly visible open source project.
  • Maning Sambale notes that diversity and inclusion are fundamental for OSM’s spread and growth, but seldom make it to centre stage. Plenary sessions such as State of the Country at SotM Asia 2016 and GeoLadies-PH plenary at Pista ng Mapa 2019 aim at increasing the audience listening to community stories. The second Pista ng Mapa (November 2020, online) hopes to feature more stories, maps and posters from the community.
  • OSM contributor hocu wrote about a changeset discussion where he (once more) realised that, thanks to OSM contributor Alikam, the OSM data is more up to date than the official sources, IETT (the governing body of Istanbul’s transport network) in this case.

OpenStreetMap Foundation

  • Christoph Hormann took a look at OSMF’s strategic reorientation and changed way of working and communicating over the past year and expresses concern and frustration about the, in his view, insufficient attention to the long-term consequences and risks of this.
  • Rory McCann (᚛ᚏᚒᚐᚔᚏᚔᚋ᚜ 🏳🏳️‍🌈) wrote in his blog about his activities in August 2020 and reports, among other things, about his activities on the OSMF Board of Directors and the Communication Working Group. mmd complained in a comment that apparently no formal candidate selection process (for the new paid positions on the OSMF) has taken place. Instead, he suspects that this was ‘all done behind the scenes’. Rory confirmed, in his response, that OSMF ‘had a preferred candidate in mind, rather than an open interview process’.

Events

  • Last weekend members from the Italian OSM community gathered (it) > en in Limone, Piemonte for a weekend dedicated to OSM. On Saturday, they gave talks and shared their OSM experiences and useful tools for mapping. Sunday was dedicated to mapping excursions around the area using OSM-based phone apps.

  • The Hungarian colleagues have moved their meetings and ‘regulars’ table’ to the Internet en.
  • A virtual mapathon will be held (it) > en on 30 September by the Italian OSM community. During the mapathon participants will draw the maps of the 78 municipalities of Benevento based on satellite images using OpenStreetMap. The event is a collaboration between Valerio De Luca (Map For Future Roma (it) > en), Luciano Amodio (ThinkSannio (it)), and Nicola De Innocentis (GeoPillole), with the support of Wikimedia Italia (it) > en.

Humanitarian OSM

  • The European Youth Humanitarian OpenStreetMap is planning a two-day online workshop on 15 and 16 October, aimed at students and teachers. The participants will learn to use JOSM and will map the streets and houses on the island of Terceira (Azores), as pre-disaster mapping.
  • The app MapSwipe is being extended to be able to compare the completeness of OSM data with airborne or satellite imagery. A first prototype was developed and tested in the LOKI project at Heidelberg University. The use case is building footprints, as they are important inputs to earthquake risk exposure models.
  • HOT detailed their strategy for achieving equal pay and organisational gender equality in a news post on International Equal Pay Day.
  • HOT is currently in a hiring push, with many jobs available, to scale up their staff to carry out the Audacious Project to map an area across 94 countries, home to one billion people.

Education

  • Daniel Feldmeyer et al. have published an article with the title ‘Using OpenStreetMap Data and Machine Learning to Generate Socio-Economic Indicators’ in the International Journal of Geoinformation. A remarkable sentence from the abstract: ‘OSM provides an unparalleled standardised global database with a high spatio-temporal resolution. Surprisingly, the potential of OSM seems largely unexplored in this context’. In their study, they used machine learning to predict four exemplary socio-economic indicators for communities based on OSM data.

Maps

  • Camille Scheffler announced (fr) > en on Talk-fr that magOSM (fr) > en, a project of services linked to OSM thematic data from the Magellium company, offers four new thematic layers at the level of France (fr):

On Sunday, October 4, 2020, 25 Swiss castles invite you to the 5th National Castles Day. Their gates and drawbridges will then be open from 10 am to 5 pm for a varied program. So – come on in!

The association Wikimedia CH and the Swiss OpenStreetMap association (SOSM) will complement the event with a Swiss Fortresses Day 2020 (Burgentag 2020). Young and old medieval enthusiasts alike are invited to discover a castle ruin on their own. You decide the program yourself. Every castle has a history and many have something mystical about them. And there is often a fireplace nearby. Find out more with the following tips:

  • Map with selected castle ruins sites (see picture below),
  • A photo challenge to upload missing photos of castles.

Illustration: Interactive online map of selected castle ruins (realized with uMap and with OpenStreetMap data). [Large map]

The photo challenge is simple: Work through this list of castle objects without pictures and upload the photos to Wikimedia Commons! For each uploaded photo there is a tweet (from @trending_places) with the hashtag #CastleProject. The photo is then usually immediately visible on the Castles project map.

The interactive online map of selected castle ruins shows a hand-picked selection of castles in Switzerland that are freely accessible and easy to reach. Depending on the castle, it can be up to one kilometer (i.e. approx. 20 min.) or more away from the nearest public transport stop or parking lot. Please follow the signs and treat nature with respect (e.g. make sure that there is no danger of forest fires in the area, watch out for ticks, don’t leave litter).

The map contains only a small part of the castles and palaces as they are managed in the Castles Project Switzerland. The Castles project links open data directly from the four open data projects OpenStreetMap, Wikipedia, Wikidata and Wikimedia Commons (photos).

The Swiss Burgentag 2020 was initiated by the SOSM association and Wikimedia CH. The event is also kindly supported by the Swiss Castle Association. We thank the association ‘Die Schweizer Schlösser’ for agreeing to link the two action days Swiss Castles Day and Burgentag 2020.

Chronicles of mapping a Canadian village

A few years ago, Esri got their hands on amazing, high-res imagery of a few urban areas in the province of New Brunswick, Canada. I found this out through the Canadian tasking manager when I was a newbie looking for ways to contribute. I can only say that I stumbled upon a gold mine. Way back in 2017, I contributed to the cities of Edmundston and Moncton. When I came back this year, there was no

A few years ago, Esri got their hands on amazing, high-res imagery of a few urban areas in the province of New Brunswick, Canada. I found this out through the Canadian tasking manager when I was a newbie looking for ways to contribute. I can only say that I stumbled upon a gold mine. Way back in 2017, I contributed to the cities of Edmundston and Moncton. When I came back this year, there was not much work left to be done in those areas and I moved on to a new project: the towns of Bathurst and Beresford. I started back in May when I was looking for some distraction during the lockdown and I picked it back up at the start of September because I was looking for some distraction from college work. I decided it would be nice to share what I’ve been up to there with the community so here it goes!

The goal

The aim of the Tasking Manager project was to just map all the buildings. Because, well, there were none at all. As I started working though, I noticed there was much more that needed to be done than just adding some buildings. Most of these areas have never been properly mapped.

CanVec

Large parts of the Canadian map have been imported from CanVec, a vector map provided by the Canadian Natural Resources organization. In the area of Beresford, the import happened back in 2012. That’s already eight years ago. And the quality of the data wasn’t particularly great. Roads are inaccurate, forests cover half the urban areas, bridges aren’t actually placed over the water, you name it.

Mapping the town

Since the imagery that Esri offers is so good, I decided I’d do more than simply add the buildings. I have been mapping as much of this town as I possibly could. That includes the buildings of course, but also the landuses, the roads, paths, forest tracks, beaches, and even power lines. I’m taking it in small steps, usually two or three changesets of about 1500 edits per day.

The work

You can’t edit OpenStreetMap and not expect to run into issues. I’ve been having a lot of them… Let’s start off with an image to illustrate what I’m talking about. This is a raw CanVec import from 2012. Let me also mention that the layer=1 tag was missing from that bridge. Luckily though, these are obvious issues, easy to fix and there aren’t that many bridges in the world so I won’t be losing sleep over this. But sadly there’s a lot more wrong…

Dealing with the imports

The CanVec imports contain mainly roads, boundaries and landuses. The basic map stuff. Except for some reason, the only real landuse in this area seems to be wood, water and wetland. No residential areas and no meadows or other grassy fields. But what’s worse is the precision of the data. It’s beyond bad. I’m all for having a good base to work with when we don’t have anything better, but this is just a pain in the butt to work with. Let me just show you some pictures.

I highlighted some roads, feel free to be horrified by everything else you see: Roads Some multipolygons have overlapping inner ways, where one way is tagged with water for example (blue inner color), while the other is part of the relation (grey border). Let’s forget that there is no actual lake here. Many of the multipolygons are enormous, connecting in places where they shouldn’t. Great accuracy

Fixing the landuses

Fixing up the landuses actually takes the most time of all jobs. I’m splitting up multipolygons that span up to several dozens of square kilometers with sometimes up to a hundred different members. Next I need to retrace the edges of the landuse accurately so that houses don’t end up in the water or in the forest. I’m a perfectionist and sometimes my outer ways end up in the thousands of elements. Finally, verifying that I didn’t break the relation by cutting off portions and making new ones takes time. Thanks also to the JOSM validator for helping me out.

Figuring out what to do with the new land is sometimes tough. It’s not always entirely clear why the original CanVec map has the elements it has. Why are there lakes when I see only trees on my imagery? Or worse, wetland… It might be a swamp for all I know. Discovering the difference between scrubs and forests is also tough, since all the footage is from the winter. I regularly struggle to find a fitting landcover tag for some of the stuff I see, of which I am sure it would fit.

Fixing the roads

Fixing roads is one of the most satisfying things to do. It’s beautiful to see a janky line turn into pretty curves with a few clicks and adjustments. Especially when there is a center line to use as reference for the center of the road.

Fixing the coastline

This one is dangerous. I have never done much coastline mapping and this one proved to be a tough one too. See, this town has a little bay with several river estuaries. The coastline extends into this bay all the way up to the edge of the river. But it’s also full of marshes that were never mapped. I tend to be pretty precise in these things if the imagery allows me to, and that’s what I did then. I had to make many edits to the coastline to get it consistent and good-looking. Every time I had to click away JOSM’s warning that I was editing an incomplete relation (mind you, the Gulf of St. Lawrence relation contains 11.4k elements), I died a little inside and prayed that I didn’t break anything. To give an idea of how precise exactly I’ve been mapping this stuff, take a look at this screenshot…

Mapping style

Part of the reason for writing this diary entry is to record my mapping style for any future mappers that will be working in this region. I hope to give a little more explanation about the history of the map in this area and the decisions I made. Feel free to comment and give your opinion on it!

First of all, since I live on the other side of the Atlantic Ocean, it’s hard to find much more information than what I get from the imagery. Everything that I’m mapping is therefore staying very neutral in terms of tagging. All buildings are simply tagged with building=yes, because it’s impossible for me to know for sure whether it’s residential or something else.

The landcover

My most important rule for mapping landcover is to keep the areas as small as possible, but at the same not smaller than necessary.

Forest

I keep the forests separated by major roads, i.e. roads that cut entirely through a forest. Even when there is forest on both sides, and it will technically feel like you’re driving through the forest, if the road is wide enough I find it a good reason to separate the ways there. It keeps them manageable in size. Several square kilometers seems to be a good measure. Other delimiters in this area are power lines, highways, railroads and rivers.

Many of the forest objects in the area are split up from larger multipolygons and have their roots in the CanVec import. Sadly though the history of the way won’t give away that information because OSM doesn’t support the transferring of an object’s history to several objects (for good reason, imo). I’ve also removed many of the original source=NRCan-CanVec-10.0 tags when they were not relevant anymore. Meaning, when I retraced the original object. I believe that the source tag should represent the source of the current state of the object and with the amount of changes I make to each object, it simply doesn’t do that.

I generally prefer to tag forests according to their usage (natural=wood for wild forests and landuse=forest for commercially exploited forests). However, the CanVec import has tagged every single forest with natural=wood. I much prefer to stay consistent, so I’ve decided to also tag all new forest objects that I add with natural=wood. Also, it would be impossible for me to verify which areas exactly are and which aren’t used for logging. Judging by the number of forest tracks though, it seems a lot of them are.

Since so many of the forests are used for forestry, we should also consider the issue of clear-cutting. One thing that became clear from the CanVec data is that it’s much older than the images, as some areas that are marked as open land are becoming forests again on the imagery. Some mappers like to mark these areas of young trees with natural=scrub, but I decided to incorporate all newly-cut open areas in the forest. The only exception I made is when it looks like no new forest will grow there for a while. If anyone is using this map, the chance will be pretty big that a currently cleared area will be overgrown again. It only take about two years for it to resemble a forest again. See this image for reference, where I traced the forest to include the cut-down areas as well:

Tracks

Let’s talk about those too for a second. Just as with everything I’m keeping them as generic as possible. I find it bad practice however to never add a grade to them so I try to get as much clues from the terrain as I can. Some tracks go through mud, are half-overgrown and look terrible while others look really smooth. That gives me plenty of clues as to what grade they would be. It would’ve been great if I could actually go out and also add a surface tag to each of them too, but alas.

Driveways

This seems to be a controversial one. I often like to map driveways, especially if they have odd shapes, or if they are very long. The thing is, it takes a lot of time. I’ve already had one slightly bossy mapper ask me to cease-and-desist the adding of driveways because they would look bad in OsmAnd. Don’t get me wrong, they absolutely do, but I’m not here to map for the renderer. In and around Beresford I’ve not been mapping much driveways at all, except when I believe they genuinely provide useful information. I’d prefer to add them all one day but I also agree that a simple, straight, 30-meter long segment doesn’t add that much value to the map. I mapped all the driveways for one tile of the Tasking Manager though, and I’d like to add them all in the future.

(Coastal) wetlands and water

From what I can tell, this area is pretty wet. I can see a lot of small lakes and wetlands through the open forest canopy. Accurately tagging them would be a nightmare though. It’s practically impossible to tell where the edges are. Hell, I’d have trouble with that even if I could go out there and trace the edges. Even if you could, it would be very hard to decide on what kind of wetland we’re dealing with. Is it a lake? A marsh? Swamp? Pond? I’ve decided to remove most of the imported wetlands because they are too generic and clearly inaccurate to provide any good information to the map. That is, unless there is clear evidence for it on the aerial imagery obviously. In many cases there isn’t.

On the coastline however, they add a lot of value and they are clearly defined. I’ve been mapping them in detail (see earlier) but the one issue I ran into was that I didn’t know what tag to give them. They are estuaries close to the sea, but they’re in a little bay. It’s very likely the water there isn’t actually salty. Nonetheless, I’ve chosen to tag them with wetland=saltmarsh and tidalflat. I’ve been trying to be consistent with it, should anyone with better information and more knowledge on the subject come along. That way, it’s easy to change all the areas in one single go.

I’ve tagged the other water bodies as best as I could. The little lakes inside the coastal marshes have all been tagged as lake, since they are natural and not dug by people. Many houses have little ponds on their property, which I’ve tagged with water=pond.

The Millstream river was a tough one. It consisted of a huge way, it was very inaccurate and the tagging was also bad as it was all just tagged as natural=water and nothing else. There was no actual waterway=river inside either. I’ve slowly retraced the way, split it up in manageable segments and I added the waterway in the center. One thing keeps bothering me however, and that’s the several areas of waterway=rapids. The wiki page is pretty short about this tag and JOSM doesn’t really seem to care much about it. From what I can tell though, this is at best useless data, and at worst it doesn’t follow tagging conventions. I’ve let them be for the moment, hoping that someone with more experience in white water features wants to tackle it. It looks like there are many more rivers in the area that need the same work…

Buildings

Buildings are a big part of this project. I’ve been adding several thousands of houses, sheds and other buildings. Even though the imagery is good, it’s far from perfect. It’s quite impossible to tell the shape of the building footprint from just a picture of the roof. In some cases you can see the walls of the house, giving you a clue where the thing touches the ground. But in many cases, a roof is all they have going for them.

I decided to just stick to what I know and map the roof outlines as accurately as I can. Some parts of the building may simply be overhanging roofs, and I can guarantee that most of the buildings are larger on the map than in real life now. At least the shape of the roof will help map users recognize the building from the ground so the data isn’t entirely bad. Here’s a few examples of buildings in the area:

Another complicating factor is decks. Rural Canada seems to love them. Some decks are clearly built directly on the ground and would not count as a building in my book. However, there are also some that are raised. There may or may not be some cellar or half-cellar below, and in that case it could definitely be seen as a part of the house. In most cases though, it’s simply impossible to tell. So I’ve just decided that I wouldn’t map decks as part of the building in any case, except when there’s undeniable evidence of walls below it. There have been a handful of houses where this was the case.

Lots of people in the area also have these hexagonal or octagonal pavilions in gardens. I’m not entirely sure that these should be mapped as buildings because they might just be a roof on pillars. What counts as a building though, is slightly vague and I’ve decided to map these as well.

On the topic of what counts as a building, I’ve also found lots of these tunnel sheds. What they’re used for, I’m not exactly sure of. But I did decide to also map these. They are permanent enough to be added to the map at least.

Consistency problems

Edge of the HQ-imagery

The high-quality imagery only covers a small portion of the province. In this case it’s still a pretty large area but it’s not nearly enough. The big question is: what happens when I arrive at the edge? Map consistency is just as important as good-quality data. A very detailed map may give users the impression that it goes on forever, but it really doesn’t. They may start to rely on it. For now I’m just going to map the best I can up to the very edge and have a (hopefully) noticeable edge in the map data as well. Big difference

The “Strip”

There is a weird strip of different imagery in the middle of the area. It’s still good quality, just slightly worse, but the colors are different. I can wonder why but I’ll never get the answers. What I do care about though, is that there is a slight difference in alignment. The ‘main’ imagery never cuts buildings or roads, but here that does happen. I’m slightly worried that this is going to cause problems, and it also make me question how good these images are actually aligned in general.

How up-to-date is it?

We know for sure that these images are already three years old. That’s not super recent. They might even be older, but we don’t know for sure. Especially things like forestry tracks aren’t permanent. Meadows may change to farmland, forests get cut down or take over cleared areas, new houses and roads are built… The map will basically a recording of 2017 (or earlier) and not further. However that’s no argument to not use it. Obviously most things will not change and even the thing that might change still provide a much better basis to work with than nothing at all.

Afterword

Since this has basically become a book, an afterword only seems appropriate. Great job if you read the whole thing haha! For now I’ll continue mapping this area. Slowly, but surely. You’re welcome to help me out, but leave some work for me!

JOSM presets

I got tired of having to click through 4 menus and popups before being able to apply a very basic tag to an object, so I made several presets that I use a lot. They work instantly without popup so they really save me a lot of clicks. Find it here: https://gist.github.com/Creator13/2ad02d756f7ad5c39fdbe706181908eb

Placenames in KRI

I’d like to start a discussion to arrive at a consensus of standardising placenames in Kurdistan Region of Iraq.

Please comment on this entry if you would like to participate, as well as your initial thoughts and ideas.

If we have enough people who are interested in this, I will set up a more permanent place and channel for discussion (a wiki page or a mailing list).

I spend hours studying news reports and carefully tracing building outlines in Malden, noting which ones did or didn’t survive the Babb fire.

And then a bunch of wanna-be do-gooders come by and crap out HOT-quality mapping, complete with duplicate buildings, vehicles mapped as buildings, scribbled outlines, and nothing but self-congratulatory hashtags for edit summaries. I think I’m goi

OsmAnd 3.8 (Android)

September 23, 2020
(Image not available offline)

For our team a release day, it's like a progress report to the users.

Every day we are working on app improvements to make OsmAnd more user friendly. We fix mistakes, that can also occur due to massive changes that have turned basic maps into a universal tool for travellers for over 10 years.

But still, it is not perfect yet. We are not only grateful for all the positive reviews, but also thankful for the constructive criticism and your dream of a better OsmAnd.

Furthermore, here is a list of the Summer updates:

  • Updated "Plan Route" mode
  • Improved bicycle nodes visibility
  • Context menu for tracks with basic info
  • Added data sources for Online photos
  • Improved "Search" algorithms
  • Improved "Follow track" options in Navigation
  • Fixed issues with import/export of profile settings
  • What else is in this release?
  • Updated "Plan Route" mode

    We renamed the "Measure distance" tool to "Plan a route". The updated "Plan a route" mode allows using different navigation types for each segment and attaches any track to the roads. What does it mean?

    E.g. you want to have a route for your Enduro trip. The first part of your trip is a road from your home to the offroad part, the second part is an unpaved road, and the third part is a road returning home.

    Go to General menu -> Plan a route. Choose "Create new route", next click the Profile icon and choose Road Profile for the first part of our trip. After that, we add starting and ending points. The first segment is built.

    (Image not available offline)(Image not available offline)(Image not available offline)(Image not available offline)

    For the second part of our trip, we click the Profile icon and choose our Enduro navigation profile (Prefer unpaved roads) and "Next segment" (Only the next segment will be recalculated using a chosen profile). After that we choose points for our offroad trip.

    (Image not available offline)(Image not available offline)

    For the last part (going back home) we choose Road profile and add the end point of our trip. Click the "Done" button and save (and rename) our GPX file with the journey trip.

    (Image not available offline)(Image not available offline)(Image not available offline)

    Now, we click on our track, then change Appearance of the track. Click the "Directions" button, and start our trip using the GPX track which we built in the "Plan a route" tool.

    (Image not available offline)(Image not available offline)(Image not available offline)(Image not available offline)

    Next, you can open an existing track, import track, or open the last edited track.

    When you click on "Open existing track" you can select a track file to open.

    (Image not available offline)(Image not available offline)

    Now your chosen track is in plan route mode, where you can modify it for your trip. You can click the "Options" button and choose any parameters for it.

    In general, you can build a route between points. Click on this button on the screen or Options menu.

    (Image not available offline)(Image not available offline)(Image not available offline)

    Next, snap your track to the nearest allowed road with one of your navigation profiles to use this option. Here we choose Enduro navigation profile and threshold distance for calculating our route.

    When a route is built we click the "Apply" button and "Done" to save a new track or "Options" -> "Directions" for starting our trip.

    (Image not available offline)(Image not available offline)(Image not available offline)(Image not available offline)

    Here you see we can modify any track for a trip. Of course, you can delete or add points in "Plan a route" if you want to change your plan on this route.

    Improved bicycle nodes visibility

    Good news for our users with bicycle trips! We improved bicycle nodes' visibility. First, to enable viewing nodes, go to menu -> Configure profile (Cycling, for example) -> Configure map -> Routes. Then, in "Routes", choose "Show node network cycle routes".

    (Image not available offline)(Image not available offline)(Image not available offline)(Image not available offline)

    In this release we improved the context menu for tracks and added an opportunity to display the menu by tapping on a track directly on the map.

    When you tap on the track you can see all infromation about it: points, overwiew, altitude, speed.

    (Image not available offline)

    When you click the "Open Track" button, the track menu opens where you can change apperance of the track, turn on/off the track' display on the map, see graphs (overview, altitude, speed), join segments, split interval and analyse it on the map.

    (Image not available offline)(Image not available offline)

    When you click the "Analyse on map" button, you can see all the necessary information about altitude, speed, slope in each point of your track in graphs and on the map.

    When you click the "Open Track" button, you can see the track menu where you can change the appearance of the track, turn on/off the track' display on the map, see graphs (overview, altitude, speed), join segments, split interval and analyse it on the map.

    (Image not available offline)(Image not available offline)(Image not available offline)(Image not available offline)

    Added data sources for Online photos

    We added more data sources for Online photos, in addition to the existing Mapillary photos: Wikidata, Wikimedia Commons. When you click a POI or polygon you can find more pictures in Online photos.

    (Image not available offline)(Image not available offline)

    We fixed many bugs in our search algorithms. Now you can find places, points, etc. without any problems.

    (Image not available offline)(Image not available offline)

    Improved "Follow track" options in Navigation

    Click Navigation button in General screen -> Option -> Follow track. Here you can choose a track to follow or to import from your device.

    (Image not available offline)

    Fixed issues with import/export of profile settings

    We fixed issues with importing/exporting of profile settings for Custom package and Navigation profiles.

    What else is in this release?

    • Fix bugs with RTL

    Of course, this is only a beginning. There is a lot more documentation to write and the other web site content will also evolve over time. Our goal is to sort out the (often outdated) docs from the osm2pgsql repository and from the Wiki and bring them over to the new site, or write new content where needed.

    Mapping Ballot Drop Box Location

    The US 2020 Election is just 41 days away. Like some states my home state of Washington is all mail in ballots. But you don’t actually have to mail in your ballot for it to be counted. You can also drop your ballot off at any one of the counties ballot drop box locations.

    The county has a map of all their locations but it’s not always clear exactly where the drop box is located

    Skagit County Ballot Drop Box in Anacortes, WA

    The county has a map of all their locations but it’s not always clear exactly where the drop box is located. So what’s a OSM mapper to do? Go out and map them. The last two locations, Concrete and at the Sauk-Suiattle Tribe were added this afternoon. The Sauk-Suiattle is located in the Southeast portion of the county near Darrington, WA. While much of the county lies to the east, hardly anyone lives there.

    I encourage everyone to get out and map polling stations and drop boxes where appropriate.

    Tagging is simple amenity=polling_station plus polling_station=ballot_box for drop box locations. Additional tags can include operator and opening_hours.

    One surprising find was that ballot drop boxes are located in both of tribes located in the county. Sauk-Suiattle and Swimomish.


    Cable of HVDC Kontek ( https://en.wikipedia.org/wiki/Kontek ) near Rostock

    Mapping the track of underground cables is not easy. However at present, there is a good opportunity to map the track of the cable of HVDC Kontek ( en.wikipedia.org/wiki/Kontek ), as one can read on www.50hertz.com/Portals/1/Images/Presse/50Hertz_Flyer_Interkonnektor_Kontek.pdf?ver=2020-04-17-163836-167 the cable is exchanged by a new cable in great proximity of the old one.

So earth works take place, which can be easily mapped!


    I ❤️ mountain pass tagging

    So I figured I’d add it to cycle.travel’s elevation graphs. It was already in the turn-by-turn instructions, but this is still more fun.

    mountain_pass=yes or natural=saddle as a node on the highway, with a name= tag too (obviously).

    Hi!

    We are glad to announce that iOS app version development does not stand still.

    The new improved version is already available to install on you devices!

    Every day we work to make the iOS version more filled and its functionality would be equal to the Android version. Inevitably, we face bugs and mistakes on our way, that we try to fix immediately.

    Thank you for your support and feedback.

    Furthermore in the article, there is a final list of extensions and fixes:

  • Introduced “Application Profiles" with independent settings
  • New arrangement of settings by profiles and types: navigation, general, map and screen
  • Ability to import or export profile settings
  • Added data sources for Online photos
  • Added ability to download online maps to cache
  • Improved "Search" algorithms
  • What else is in this release?
  • Introduced “Application Profiles" with independent settings

    At this release, we added Application Profiles. Now you can create your own profile with independent settings.

    Go to menu -> Settings -> New profile. Here you can change order in profile list, switch on/off profiles.

    (Image not available offline)(Image not available offline)

    New arrangement of settings by profiles and types: navigation, general, map and screen

    Now each profile has its own settings. Go to menu -> Settings -> сhoose profile.

    Each profile has General settings, Navigation settings, Configure map, Configure screen, and Profile appearance menu.

    Of course, you can set Plugins for the selected profile.

    (Image not available offline)(Image not available offline)

    Ability to import or export profile settings

    You can export your profile or import other profiles.

    To import a profile, tap on the needed file (*.osf) in any application and select "Copy to OsmAnd Maps".

    (Image not available offline)(Image not available offline)(Image not available offline)(Image not available offline)

    To export a profile, go to menu -> Settings -> Choose profile -> Export profile.

    (Image not available offline)

    Added data sources for Online photos

    We added more data sources for Online photos except mapillary-photos: wikidata, wikimedia commons. When you click to POI or polygon you find more pictures in Online photos.

    (Image not available offline)

    Added ability to download online maps to cache

    Now you can download online maps to cash.

    At first, you should change online maps in 'Map type' menu. Next, long click to the map -> Actions -> Download map. Here, you can choose map area, map type, max/min zoom, you see the number of tiles and download size. When you set all parameters for downloading to click 'Download'.

    (Image not available offline)(Image not available offline)(Image not available offline)(Image not available offline)

    We fixed many bugs in our search algorithms. Now you can find places, points and etc. without any problems.

    (Image not available offline)(Image not available offline)

    What else is in this release?

    • Fixed crash while starting navigation

    • Fixed bug with OpenStreetMap Editing Plugin

    • Fixed an issue with "Nautical maps" always stuck in update state

    And remember that only together we can achieve the best results!

    New features are coming SOON!

На карте вообще много устаревших артефактов, но это поправимо :) После того как в заборе вокруг парка убрали многочисленные калитки и заделали “устоявшиеся” дыры, многие старые тропинки потеряли свои смысл и к настоящему времени практически полностью исчезли. Даже дорожки по некоторым аллеям фактически исчезли, например, по северной части Водопроводной аллеи.
