My opinion on the new Organised editing guidelines

New Organised editing guidelines was proposed by DWG. I show my "negative" opition on that guidelines.

At first, I think the previous Directed Editing Policy was a good proposal. I like that. I really pay my respects to DWG's works.

New Organised editing guidelines was proposed by DWG. I show my "negative" opition on that guidelines.

At first, I think the previous Directed Editing Policy was a good proposal. I like that. I really pay my respects to DWG's works.

Most important point

  • Scope is very vague. It could be applied to "mapping parties between friends" even it negate. I like the previous "Director/Directee" idea.
  • Imports without any advance discussion are not acceptable. Use other service.

Previous Directed Editing Policy was better idea

  • It says individual community members and organised editing groups are at same level playing field.
  • must/should/may are properly used. I can easily understand which items are more important.
  • Almost no duties for organised mapper/contributor/directee. Indicated duties are for general OMS mappers, those are not special for organised mapper.

Individual

  • They are not meant to apply to community activities like mapping parties between friends or doing a presentation on OSM at a local club.
    -> The reason this guideline is not to applied to communitiy activities is not shown.
  • any edits that involve more than one person and can be grouped under one or more sizeable, substantial, coordinated editing initiatives.
    -> I can't understand this definition
  • more substantial initiatives are expected to spend a more substantial amount of effort.
    -> What's "substantial"? Does it mean "mapping parties between friends" is "insubstantial"?
  • If the activity is a response to an emergency and no advance discussion is possible, the community should be informed as soon as is practical.
    -> No. Use other service. For example, uMap could be your solution.
  • Contributors should respond to communication attempts made in good faith by other contributors.
    -> This duty is for general OMS mappers, those are not special for organised mapper.
  • Any person or organisation whose actions affect the OpenStreetMap project has the duty to care for the project, and should respect the community’s consensus, mapping practices and guidelines.
    -> This duty is for general OMS mappers, those are not special for organised mapper.
  • Edits to the map
    -> (I can't understand why the name of this section is "Edits to the map")
  • People looking at individual changesets that are part of a organised mapping activity should be able to tell as soon as they look at a changeset.
    ->(I can't understand what it means)

#DigitizeRacine - Next Steps and Priorities

Thanks to some excellent feedback from the community, the #DigitizeRacine project is moving forward with great efficiency.

Microsoft's building footprints seem to be fairly accurate for Racine County, and often only need minor corrections, or a garage or two added.

In refining my landuse areas, I came across a few areas with no sidewalk. I went looking for a parcel map to reference, and came across the WI State Cartographer's V4 Parcel dataset. Not only does this give me the parcel boundaries I wanted, but it includes address information, and is freely available for public use.

So, after a bit of pre-processing, I've joined the parcel address information to Microsoft's building footprints, then split the resulting layer into a few thousand manageable chunks. I've always liked the task management method that HOTOSM uses. I grab a section or two, work on those to completion, cross them off the list.

At this point, I think the focus will shift towards the building footprints, as those are currently not in the OSM dataset. Whatever my opinions on landuse areas, those are already present, and refining existing data can wait. Adding buildings with accurate address tags is now the primary task; landuse will be the next phase. The state parcel layer also includes some zoning tags, which may be helpful in determining landuse areas.

Data import process into OpenStreetMap

One of the contributions could be used to improve the quality of OpenStreetMap is by importing existing datasets. However, if you don’t pay close attention, you may end up doing bad imports. Here, we collected some suggestions to guide you to import existing dataset into OSM correctly.

1. Type of data import

One of the contributions could be used to improve the quality of OpenStreetMap is by importing existing datasets. However, if you don’t pay close attention, you may end up doing bad imports. Here, we collected some suggestions to guide you to import existing dataset into OSM correctly.

1. Type of data import

According to documentation in OpenStreetMap, only these physical features can be imported into OSM. They are:

  • Point: locations that can be presented by a single dot on the map, for instance, bank, restaurant or post office, etc.
  • Lines: the feature can be presented as lines, for instance, roads, trails, bike lanes.
  • Polygons: can be defined as a closed line, for instance, buildings, farmlands.

In the following picture, you can see how all the physical features that show and can be rendered on a digital map.

image

2. Data format for OSM

The default dataset extension of OSM is “.osm”. OSM data files are traditionally distributed in an XML format, and indeed it is still structured very much like XML. You can see an example as the following figure.

Example:

image

Converting other dataset to OSM In Java OpenStreetMap editor (JOSM), you can only edit feature data in ‘.osm’ format. If your data is packed in other data formats, we list all the possible conversion tools in the following table that you can use to convert your dataset into ‘.osm’.

image

3. OSM data license and permission

Once the dataset is in the correct format for OSM, you may consider OSM data license or permission. There are two kinds of scenarios:

  • Scenario 1. You own the data you are going to import into OSM, so you should consider an open source or public domain license. The public domain means it will be free and open to being used by anyone for any purpose without restriction under any copyright law.
  • Scenario 2. If the dataset originally owned by a third party, you need to have the permission to import the data into OSM. To obtain a permit, you can find some letter templates here. For specific details of the permission of data ownership, you can go and view it on Open Data Commons Open Database License(ODbL). If the data owner request, it needs to be addressed in the contributions specifically.

4. OSM data importation plan

You need to create a plan for any OSM data importation you are going to take, and the plan can be outlined as:

image

For specific you can see the following examples:

Register import plan. Edit and add your import plan in wiki OpenStreetMap Page: OSM Catalogue imports.

5. Data importation and communication with OSM community

Someone else may be working on importing the same dataset you have. Your dataset may be relevant to a region but not to other parts of the world. Therefore, keeping the OSM community informed of your intention is important. Before you import your dataset into OSM, please:

  • Send the import plan to country mailing lists.
  • Subscribe to import mailing lists to hear what the community has to say.
  • Send messages to local OSM users. You can find local OSM mapper groups by:

    • User groups: shows a map of the user groups by their geolocations;
    • Who’s around me? will show users who are close to your geolocations.
  • Also, send an email to imports@openstreetmap.org image

  • Wait for approval of the import plan, if the local community has been approved your import plan, go ahead with the import process.

6. Other recommendations we have for you

  • Update your mapping project constantly.
  • Try to accomplish the schedule of your import plan.
  • When you are importing dataset into OSM, we recommend you to start with a smaller dataset. You should split a large area into smaller areas too.
  • Using high-resolution imagery, e.g. ESRI World Imagery, DigitalGlobe Standard Imagery, DigitalGlobe Premium Imagery, or Bing Aerial Imagery, to evaluate your dataset are recommended, but be minded that the imagery can be out of date.
  • Ask local mappers to validate and update your data that imported into OSM.

Questions?

Let me know if you have any questions.

Make Visakhapatnam’s map great again.

Firstly I want to thank mappers who had put their deliberate effort in creating and improving the data in Visakhapatnam. The road network in the most of the areas is almost mapped and there are few missing roads. As Bing aerial Imagery, Esri world imagery, DigitalGlobe Imagery looks solid, we picked them as resources for the mapping according to the updated imagery. I appreciate Martha Leena,

Firstly I want to thank mappers who had put their deliberate effort in creating and improving the data in Visakhapatnam. The road network in the most of the areas is almost mapped and there are few missing roads. As Bing aerial Imagery, Esri world imagery, DigitalGlobe Imagery looks solid, we picked them as resources for the mapping according to the updated imagery. I appreciate Martha Leena, Chanda Teresa, Naga Bhavana and Iqhra Aiman for teaming up with me for this Mapping campaign. As an initial phase we’d like to concentrate on the Visakhapatnam division

diary Pic credits: Deccan Chronicle

We made a plan to map the features in the following order, so that we can concentrate on particular feature and improve that.

  • Align the roads and create the complete road network according to updated imagery.
  • Improve the building coverage all over the Visakhapatnam.
  • Do Mapillary drives with the help of local community in the Visakhapatnam and try to achieve a - complete Mapillary coverage.
  • Adding road names,Point of interests,amenities and other map features using Mapillary resource we collected.

Changeset comment: #Improving the roads and buildings in the Visakhapatnam
Source: Bing aerial Imagery, Esri world imagery, DigitalGlobe Imagery

Note: The above plan is just for our team to maintain consistency in our campaign, so that we can track the features we are adding and for smooth journey of mapping.

I request all the community members to join us. Looking forward for the suggestions and improvements. We would like to continue this and try to make OpenStreetMap better in Visakhapatnam.

Open Location Code, OLC, generator & search on the OSM map

The OLC is supposed to become a kind of global address system. It is especially interesting for regions with obsolete or nonexistent on-the-ground addresses.

I wrote a simple Open Location Code generator & search on the OSM map: http://ausleuchtung.ch/olc/.

To generate an OLC code just click on the map at a certain location. The search box or an URL link are to be used to find a location for an OLC code. For example, here is the location of the Norfolk Island Central School stadium: http://ausleuchtung.ch/olc/?c=5V29XX59+JHW

The Google map supports the OLC too via its search box.

One of the great advantages of an OLC address is that it can point to an exact location of an apartment or an office in a large building, what potentially can save a lot of time and fuel, for example, for a delivery service vehicle, and by this reduce the CO2 emission.

This Wikipedia article about the Open Location Code provides detailed information on how the open source OLC system was created and how it works.

Creating MapMate Picture Files for Ireland

H34 Base Map for Map Mate Hillshaded
H34 West Donegal: Vice County raster map suitable for MapMate
Source data: (c) OpenStreetMap contributors; hill shading NASA SRTM via viewfinderpanoramas.com

One of the things I'd always planned to do once I had a half decent data set for the Irish Vice Counties was to create detailed raster maps for each of them. This is mainly because I've found using such raster maps useful for my own biological recording using MapMate software. They make choosing the correct recording location much easier, and reduce the hassle in producing more attractive (and communicative) outputs. I've detailed the principles behind the creation of such maps here in the past.

With the first such map I produced I struggled to get it to align properly with the Irish Grid displayed with MapMate. I could upload MapInfo .MIF files which would align, but these offered nothing like the degree of detail I want to show. Furthermore the import process with my copy of MapMate only seems to work with polygons. I tried a variety of ways: mainly trying to tweak the .TAB file format which I'd used successfully with files for Great Britain.So I put the idea to one side.

Very recently, prompted by Julia Nunn, VC recorder for County Down, I re-looked at the problem. Once again I was getting nowhere and  I was on the verge of seeking expert help from Richard Cantwell on the arcana of MapInfo's formats, many of which date back to the 1980s. (Richard works professionally with MapInfo data a lot and has written some very informative articles available from his firm's website.)

Note.  Much of this post will mainly be of interest to users of MapMate. However, towards the end I digress into geonerd territory when discussing the pros and cons of MapMate's technical choices about projections. Also please note that has been sitting in my draft folder for a while before being published.


I soon realised that there was another approach I had not tried.

MapMate allows one to 'calibrate' a raster image by clicking on two locations and entering the grid co-ordinates. I have always found this a bit chancy and tedious to set up, and even then one is still often a pixel or two out. Even with this approach I was failing: I could get a raster map registered but it would be to the British not Irish Gird. Whilst doing this I finally remembered that MapMate will save a given map as a bitmap with an associated calibration file. This finally gave me proper insight as to how to crack the problem.

What I did was create a map of County Down in MapMate using its own internal data, and then saved this as a calibrated bit map. The calibration files are rather simple:

  <mapmate>
  <cal>
    <name>test.jpg</name>
    <timestamp><timestamp>
    <copyright></copyright>
    <units>m</units>
    <datum>WGS84-modified</datum>
    <projection>Local</projection>
    <coodtype>EN</coodtype>
    <rotation>0</rotation>
    <type>raster</type>
    <xo>-160000</xo>
    <yo>200000</yo>
    <xi>-50000</xi>
    <yi>290000</yi>
    <xpixels>4400</xpixels>
    <ypixels>3600</ypixels>
  </cal>
</mapmate>


The key parameters being the bottom right and top left in MapMate's internal co-ordinate system, and the size of the raster file in pixels. To make life easier for myself I took the initial MapMate map and used the option to re-frame the map to the 10km grid. I could then write down both the grid co-ordinates and the internal MapMate co-ordinates for the map bounds. I did this for all Irish Vice Counties (although MapMate wouldn't snap to the grid for a couple, and its bounds for Fermanagh
were broken), and recorded all the values in a spreadsheet.

H38 County Down : MapMate test map
First MapMate test picture map for County Down
Data: (c) OpenStreetMap contributors
Now using QGIS all I had to do was create a raster file with exactly the same bounds as the MapMate map. By setting the print option to 254 dpi I get as close as I can to 100 dots per cm which makes for easy computation of image sizes. I scaled maps to be 1:250k which is convenient both in terms of detail and effective for all vice counties. The largest dimension was around 5600 pixels, but most rasters were roughly 4000x4000. Once I'd tested out a quick draft of County Down, I then produced rather more considered maps of the 2 Donegal vice counties. These were made by using Overpass-Turbo queries to get specific features within a vice county and saving them as geojson files.

Hillshading



You can find all these places on this map because it shows a much larger area on a much smaller scale than the previous maps.
Collins Progressive Atlas page 12 : my introduction to hill-shading, contours & hypsometric tints.
I was about 6 years & 4 months of age.
I also wanted to add hill shading and hypsometric tints. These help a bit in quickly identifying locations for data entry, but are of much greater value for someone looking at the distribution of a plant. Ultimately I may produce multiple versions suitable for different contexts: for instance the recently published Derbyshire Flora uses geology, or hypsometry as a background where this informs interpreting the distribution of a plant.

Another motivation for doing this lies way back in my childhood. I was given a book at Christmas when I was six called Collins Progressive Atlas. I still have it, and flipping through its pages I'm amazed at its ambition in teaching map reading & many of the principles of cartography to young children. The image above shows on a 2-page spread it introduces some rather sophisticated concepts. (An aside: I'd love a way to do something like the 3 opening page spreads for anywhere in the world. OSM is a perfect starting point).

To do this I downloaded raster DEM files from ViewFinder Panormas, and processed them in QGIS to produce hill-shading, contours and tints. I did so pretty much using the standard defaults : these can be improved upon as can be seen from the work of folk like Andy Allan (Thunderforest) and Richard Fairhurst (cycle.travel).

Having done this I worked through all 40 of the Vice Counties: the images are currently available on Flickr, but I have will eventually add added them on github along with the relevant calibration files. Thes should be usable directly in MapMate if all three files with the same base name are copied to the same directory.

MapMate's Co-ordinate system

The last thing I wanted to do was understand MapMate's internal co-ordinate system.

To do this I created two geolocated images which were 100 km square (basically the Irish Grid Square C and the British Grid Square composed of half each of NW & NR  I made sure I had both grids visualised in the images. I then created MapInfo calibration files based either on bottom-left (corresponding to Irish Grid) or top-right co-ordinates (assumed British Grid).

Using QGIS I created raster images with both Irish (grey-brown) and British (blue) grids.
I then loaded them into MapMate, and overlayed these with the coastline data which comes with MapMate.

100 km sq. British Grid (from NW05 to NR49)

100km Irish Grid sqaure C. British Gird in blue.

As was already clear, MapMate uses a kludge. Irish Grid co-ordinates are mapped internally onto squares of the British Grid. It should be possible to work out which 10km squares belong to which grid system along the boundary (at least I assume the border is aligned on 10km grid lines).

MapMate internally uses an Access database without any geospatial features. It also only allows its notional recording units to be grid squares (AFAIK, of any size from 1m to 10km), which helps because most geospatial calculations can be done using simple arithmetic. It does recognise that any particular grid square is within one of its internal polygons (local authority & vice county boundaries). As it does this quickly there may be a bit more to the code than just sums.

The decision to rely on the useful properties of a regular kilometric grid, and effectively hard-wiring two grids into the code, has an unfortunate consequence for MapMate. It is not a practical tool for biological recording outside the British Isles (although I think at one stage it was adapted for Luxembourg). Whilst the Dutch & Swiss use 10km grids for recording, most other countries with well-established recording systems use some variant of a latlon grid: in Germany sheetlines of 1:25k maps are used in Baden-Württemberg, elsewhere it's often a 7.5 or 15 minute 'square'. (MapMate also suffers from being based on old technology, but that is another (huge set of) issue(s)).

Coda

MapMate is still a phenomenally useful piece of software, widely appreciated by its users as being straightforward to use, but it increasingly suffers from both being based on very old software, and a business model which does not provide enough recompense for continued development.

At the same time the newer approaches of web-based and app based data entry do not yet deliver all the same functionality. I've tried address one deficiency of MapMate with more accurate maps delivered as images. However it cannot fix how MapMate internally validates records based on boundaries. I do believe that this and  similar approaches can be used to maintain or extend MapMate's utility until newer software reaches a similar level of functionality.

Further thoughts on Public Rights of Way

Have walked a substantial part of Watlington civil parish in two outings recently, upon resumption of my excursion through the Oxfordshire Chilterns checking the Public Rights of Way. The weather on both occasions has been magnificent and the areas have been a delight to walk and view.

Have walked a substantial part of Watlington civil parish in two outings recently, upon resumption of my excursion through the Oxfordshire Chilterns checking the Public Rights of Way. The weather on both occasions has been magnificent and the areas have been a delight to walk and view.

I have had Harry Wood's diary entry, "Using Rob Whitaker's tool to map UK Public Rights of Way" at https://www.openstreetmap.org/user/Harry%20Wood/diary/45022 on my mind. It was interesting and thought-provoking to read. I believe Public Rights of Way are a fundamental fabric of our lives that helps make us who we are as a nation, historically. Harry writes, "But also it feels a bit like littering our data with 3rd party arbitrary reference codes. prow_ref values are certainly not verifiable on the ground!" There might be so many more elements uploaded to OSM thought to be "littering our data" before considering PRoW references, or tags, I feel. I should promote, rather, how this data might be used for everyone's benefit. I agree the values are not verifiable on the ground, usually. There are examples in some of our civil parishes in South Oxfordshire, however, where it is the Chiltern Society, I believe, that has been responsible for adding its own references to trees, fence posts and suchlike. These are the codes it uses in its series of 32 Footpath Maps and which I add as tags in OSM to all the ways I walk. I have written in an earlier diary entry, "My ongoing relationship with OSM", of how I have been able to download Oxfordshire County Council's PRoW data, add elements to it and import it as a .kml file to Locus Map on my Android 'phone, and use Vespucci, also, to have every piece of information to hand as I walk. I find this necessary because OSM offers no facility to use keys such as "prow_ref" or "ref:Chiltern_Society" instead of "Name", or any app developer using OSM, so far as I know. How much easier it would be for every walker in our technological age were this possible. Additionally, my overlying Oxfordshire County Council data distinguishes between PRoWs and other footways that are present very much in OSM, giving a walker/rider confidence when in the countryside.

There is another aspect of walking PRoWs that fills my time, too: barriers. The Chiltern Society has done terrific work in my area of South Oxfordshire to replace stiles with kissing gates or gates, for which it should be commended. I walk as a helper with a visually-impaired group every fortnight. It has been so revealing on two counts: 1. it takes quite some time for each blind person to negotiate a stile and 2. most stiles do not have the facility to pass an assistance dog through, making it necessary to lift the dog, causing distress both to it and its owner. How much more enjoyable are the walks where they consist of gates and kissing gates, alone. My hope is that, by adding these barriers to OSM, it might be possible to compile a route and obtain a list of obstacles on it. That should make for a much more enjoyable walk, not only for the visually-impaired but others who might find stiles too much to negotiate, and give them the assuredness that none will be encountered. I wonder if an OSM contributor might create a simple method of carrying out such an exercise in one of its editors such as JOSM, say? Alternatively, I am reminded, suddenly, of my topic in Talk-GB last year here, https://lists.openstreetmap.org/pipermail/talk-gb/2017-October/020702.html, where I received extremely helpful replies from Roland. https://overpass-turbo.eu/s/sh7 identifies all PRoWs in Checkendon civil parish, if within the map area, having stiles. Removing line 3, "way(bn)[prow_ref];" in Overpass Turbo and rerunning the query displays the stiles themselves. How all of this might be made available to the wider public, I am not sure!

Faux stone is made from Portland cement and iron oxide pigments for coloration. It is mass produced, which accounts for it generally more reasonable pricing. This is also why it weighs less than natural stone siding.

Ann and I took a break from work to fly via Istanbul to Dushanbe, Tajikistan, where after 40 years of variously studying, living, working, and traveling in the former USSR I finally made it to the 15th former Soviet republic. Somehow I had never managed until last week to visit Dushanbe. Of course I could not roam the city without collecting Mapillary imagery (mostly uploaded by now) and adding to OSM interesting sites we visited, or updating and augmenting the tags on existing entries.

One of the more interesting and engaging sites we updated was the three-room Museum of Musical Instruments. Watch this video with the sound turned up!

We also stopped in Istanbul en route and I visited the old neighborhood where I lived 1988-1990. I'll be adding names of some streets in that section of town based on Mapillary imagery.
