OpenStreetMap User's Diaries

Story so far

     I was introduced to Opensteetmap by the Unique Mappers Team (UMT) Port Harcourt at the #1 MAPATHON training led by Mr Sunday Victor. He showed how to get registered on Openstreetmap and how to map. For the training, we (those available for the training) worked on project 400 using osm which involved mapping features such as buildings and roads in The University of Port Harcourt and 

     I was introduced to Opensteetmap by the Unique Mappers Team (UMT) Port Harcourt at the #1 MAPATHON training led by Mr Sunday Victor. He showed how to get registered on Openstreetmap and how to map. For the training, we (those available for the training) worked on project 400 using osm which involved mapping features such as buildings and roads in The University of Port Harcourt and I was added to the Let's Map Our World whatsapp group. From the group, I got to know about The STALL CATCHERS. I participated in the worldwide Catchathon which helped Alzheimer's research. I had a wonderful time catching stalls with the Unique Mappers Team. It was a really fun experience and I enjoyed the pizza.
     I participated in osm task #project-3530 #MXEarthquake 2017 with the guidance of UMT. Alone, I attempted #project-3443 Sierra leone - Regent, Kamayama, Kaningo- Landslide affected area using OpenStreetMap but failed to edit and save  the changeset.
    I have also worked on #project-4370 #mappingperi-urban areas, Lusaka. Mapping this area was successful. 
    I met with the coordinator of Unique Mappers Team, Mr Sunday Victor on Monday 23rd April 2018 for a formal interview and registration as a full member of Unique Mappers Team, Port Harcourt.I am indeed glad to be a Unique Mapper Team member. So far, it's been fun and I know there's a lot more. I'm willing to dedicate my time and passion to mapping the world as long as it does not make me go down academically. This I strongly doubt because I love mapping as well as my course of study, Geography and Environmental Management. I believe spending reasonable time on both will actually help me improve on both. Thanks to OpenStreetMap and my field of study, I'll get to know and map, and soon, visit different parts of the world.

Meets with UniqueMappersTeam Coordinator, I joined LetgirlsMap chat group.

At State of the Map we love hearing what has been done with open map data, but we also love seeing it too. This year we’re taking inspiration from regional SotM EU conference and holding a poster competition. Your poster could show how well your home is mapped, it could be a beautiful new style or map. It might not focus on a map but instead focus on a community or statistics, it might be a poster explaining and inviting people to OpenStreetMap. What’s important, is we want it to be about OpenStreetMap.

Rules for the competition

  • Poster should be for A0 size (841×1189mm)
  • Poster should be about OpenStreetMap
  • One entry per person

How to enter

  • Upload your poster online
  • Send an e-mail to team@stateofthemap.org with the subject “Poster Entry
  • Include: a link to the image, title of the poster, your name(s), whether you would like to bring the A0 poster or for us to print it. The licence of the submitted works is considered to be CC BY-SA 4.0, unless noted otherwise on the image.

Deadline: 30th June 2018

With the entries

  • The SotM team hope to shortlist up to 20 posters that will be displayed during the State of the Map 2018 conference in Milan
  • During the conference, attendees will be invited to vote on their favourite posters
  • As of this time there are no prizes planned other than the satisfaction of sharing your poster with the State of the Map community.

You don’t have to attend SotM 2018 to enter this competition, but great conversations happen while viewing the posters so grab your SotM tickets here!

Norwegian airlanes are Openstreetmap user

I learned yesterday that Norwegian airlines use openstreetmap data in their entertainment system. Looking for my edits at 12000 m was fun! :-) They don't use vector map, but instead they seem to use raster tiles. The quality doesn't go detailed street level, but it's not required for a flight map.

NCN422 cycle route - Theale to Bracknell

I rode from Theale to Bracknell today to check on the progress of the NCN422 cycle route. There are still large holes, and it's mostly shared use paths rather than proper infrastructure. It will probably be a month or two before I get round to updating OSM with my findings,as there are other things in the pipeline.

Additional insights about OSM changeset discussions: Who requests, receives and responds?

Last year I wrote two blog posts about the OpenStreetMap (OSM) feature that allows commenting on contributor map changes within a changeset. The first blog post showed some general descriptive statistics about the number of created changeset discussions, affected countries, the origin of the commenting contributors or their mapping reputation. The second post described a newly introduced feature, where contributors can flag their changeset so that their map edits can be reviewed. This blog post will follow up on this topic and conducts some similar but updated research.

The first chart shows the number of created comments (discussed changesets) and the contributors involved over the last 15 months. The number of created comments and discussed changesets fluctuates over time, whereas the number of contributors who take part in changeset discussions stays consistent at around 1,500 per month. Around 3,200 contributors received a comment on at least one changeset’s map edits a month.

After publishing the aforementioned blog post, people were asking for some numbers that show the commented changeset grouped by the editing application that was utilized. The results show that these numbers stayed more or less the same with 2/3 of all commented changesets (almost 160,000) being edited by the iD editor. This is not very surprising since this particular editor is used by many OSM beginners during first edits. It’s also interesting to see whether the changeset author responded (also grouped by the OSM editor that was used). Overall only around 32,000 contributors responded to their changeset comment. You can find some additional charts about the comments per discussed changeset in the previous blog post. Again, the majority (around 71%) of the changeset discussions contain one comment only.

Since last August, contributors can mark their changeset with a flag for “review_requested”. After a few months now I think it’s time for a first look at the numbers. The following charts display the number of requested reviews by contributors and their marked changesets. First of all, almost each month around 7,000 contributors asked for one review minimum. Overall almost 36,000 changesets have been marked for review each month. If we take a close look and filter changesets by hashtags, we can see that sometimes large numbers of the changesets are contributed by #HOTOSM or #MissingMaps members.

The following diagram shows probably the most disappointing results: The number of requested reviews that actually have been reviewed in the end. No matter if the changeset has the #HOTOSM or #MissingMaps tags or not, the relative value of reviewed changesets lies only between 6 and 18%. To be honest, I’m also a bit surprised that only a few of #HOTOSM or #MissingMaps changesets have been reviewed so far.

So, what do you think? Do you review contributions without commenting on the changesets? Do we need more attention here or is it just boring to look after changesets which are marked for review? I think it’s obvious, that we need more contributors who review map changes or least “documenting” their work. But can we handle this? Or do we need better tools?

Thanks to maɪˈæmɪ Dennis.

Simple script to bulk update the admin_level=? on boundary=administrative ways

Sometimes we find in some cities/countries some boundary ways (the ones that define the political borders of provinces/towns/countries) that has no tag. Example of boundary way without any tag: ♦

For the renders and 3rd party apps that is not a big problem because that way is indide the the corresponding relations with different admin_level, it can be shared by one or many relations, bu

Sometimes we find in some cities/countries some boundary ways (the ones that define the political borders of provinces/towns/countries) that has no tag. Example of boundary way without any tag:

For the renders and 3rd party apps that is not a big problem because that way is indide the the corresponding relations with different admin_level, it can be shared by one or many relations, but in my opinion is a good practice to also add tags in the way, specially to avoid amateur users(that don't understand the relations yet) to delete them thinking that are unuseful(I know from experience).

That's why I decide to make a simple python script that parses the .osm file, checks all the ways that belong to a boundary=administrative relation or to many, and updates the way with the lowest/minimum admin_level number found(that way is easier to see that that way is between 2 countries for example, or between two counties or provinces).

The script is the following, based on Dmitri Lebedev's osm2python library (not python3 compatible yet, help migrating).

# -*- coding: utf-8 -*-
# Use python2, since osm2python is not ported to python3

from osm2python.tree import load, dump
from collections import defaultdict

origin_osm_filename = 'boundaries.osm'
destiny_osm_filename = 'boundaries_updated.osm'

# loading the .osm file
osmtree = load(open(origin_osm_filename))

ways_min_admin_levels = defaultdict(int)
for i, r in osmtree.relations.items():
    if 'admin_level' in r.tags:
        admin_level = int(r.tags['admin_level'])
    else:
        print(r, 'has no admin_level')

    for way in r.members:
        if ways_min_admin_levels[way.ref] == 0 or ways_min_admin_levels[way.ref] > admin_level:
            ways_min_admin_levels[way.ref] = admin_level

for i, w in osmtree.ways.items():
    w.tags['admin_level'] = str(ways_min_admin_levels[i])

# Saving to .osm
dump(open(destiny_osm_filename, 'w'), osmtree)

The result example looks like this: As you can see the way now has admin_level=5 which is the minimum level of all the boundary relations that way is inside of.

I hope it is helpful for you and you can hack it to do more things than needed.

  • Vote on the public transport hail and ride proposal until April 24th.

Community

  • Pascal Neis mentions on Twitter that changeset 51820940 is the one that had the most comments (113). The issue is that Belarusian is the official language on the ground in Minsk, Belarus, but the local population speaks Russian there, so all the names were added in Russian in the name tags.
  • Dominique (@dominique_hoavo) presents on Twitter a review of the Girls Map for Togo initiative (#GirlsMap4Tg) that occurred April 11th to 13th.
  • User Escada interviewed Andrew Harvey from Australia for his Mapper of the Month series.
  • Jakub Klaučo explains how he created a high-resolution world map poster, using Python and TileMill. He is currently accepting suggestions on how to wrap around the 180th meridian.
  • Daniel Begin, Rodolphe Devillers and Stéphane Roche published a paper called The life cycle of contributors in collaborative online communities – the case of OpenStreetMap in the International Journal of Geographical Information Science.

Open Data

  • The beta version of the Wheelmap now includes information about the operating status of elevators and escalators of Deutsche Bahn. (via Twitter)

Programming

  • In the previous issue we reported on Arne Johannessen’s thesis on the generalisation of roads. A small discussion about generalization in general has started on the osm-dev mailing list as a result.
  • Leaflet developers are considering to drop support for versions 8 to 10 of Internet Explorer.
  • Andy Allan posts about his work on refactoring the code of osm.org, so that it will be easier to add new features: This should help to attract new developers.
  • The Heidelberg Institute for Geoinformation Technology (HeiGIT) released a new open source microservice for searching OSM points of interest (POI) through specifying feature-buffers, polygons or bounding box. It returns GeoJSON features or simple statistics of categories. Are there any Python developers interested in contributing?

Releases

  • Komoot’s open geocoder Photon reaches version 0.3.0, which includes major updates of software dependencies and a number of improvements on reverse geocoding, house number handling and location bias computing.

Other “geo” things

  • Jessica Sena posts the process behind the Streets of Women (#LasCallesDeLasMujeres), a project by GeoChicas using Mapbox and NamSor APIs.
  • Páraic and Pearse McGloughlin created “Arena”, a mesmerising film made with satellite imagery from Google Earth.
  • Despite Australia’s rather accurate mapping on OSM, some people insist on believing it doesn’t actually exist. This theory is only the last of many conspiracies or jokes that deny the existence of countries and cities around the world, listed in this article from The Guardian.
  • Mapillary announces a new, 15 million USD round of investment with BMW i Ventures, Samsung Catalyst Fund, and NavInfo joining in as investors.

I-295 Redesignation

www.openstreetmap.org/edit?way=479914933#map=20/40.28546/-74.72373

I have updated some of the missing roadway name to I-295. But why the roadway shield still shows I-95 (Zoom in on roadway section and observe roadway label in the back)

— Yay, new mapper! Welcome to OpenStreetMap!

— I see you are using wrong tags. Please read Map Features and don't come back until you're done. I don't care if it's too long. Go to Google Map Maker if you're intimidated.

— I don't know you. Please go to talk@ mailing list and introduce yourself and reasons for your mapping. Yes, I know you have to sign up using some obscure web page, and then receive unwanted mail for eternity. But rules are rules. Go do it, or leave.

— I see you work for a mapping company. I will be watching you, because you do not care for our map. None of you do. Yes, I am working at such company too, but I care.

— I caught you not tracing from Bing like the rest of us. Please explain your sources and acquire specific permissions for using these. Or better stop.

— I see that among 500 buildings you've traced, 20 have been recently demolished. I know that they are still on imagery and in the registry. But it looks like your quality of mapping will never reach mine. Please go away and never come back.

— Hey, I've seen more edits from you. I think we've discussed it. I don't care if they are good, I have reverted them. Please do not come back.

...

— Hi new mapper, welcome to OpenStreetMap!

How We Improve OpenStreetMap

At Development Seed we’re always looking for ways to contribute to open source projects. Recently, we started thinking about how we might be able to help improve the OpenStreetMap (OSM) ecosystem of tools. Of course we had our suspicions, but to insure whatever we came up with had the whole OSM community in mind, we started with a round of user interviews. Below you’ll find our process and findi

At Development Seed we’re always looking for ways to contribute to open source projects. Recently, we started thinking about how we might be able to help improve the OpenStreetMap (OSM) ecosystem of tools. Of course we had our suspicions, but to insure whatever we came up with had the whole OSM community in mind, we started with a round of user interviews. Below you’ll find our process and findings, in hopes that we can all start supporting tools to serve the greater community.

Process

User interviews are essentially what they sound like, interviewing users to better understand who they are, what they do, how they use OSM tools, and what they feel could be improved within the OSM ecosystem. To try and capture the opinions of such a large group, we broke up the community into 3 different groups:

  • Inexperienced mappers, ones who had only mapped a few times
  • Experienced mappers, including people who map for their work vs people who map on their own
  • People who want map data, people at organizations like American Red Cross or HOT

We interviewed at least 4 people from each group, to ensure that we were hearing from a number of different voices. For the 19 different people we talked to, from Belgium to Japan, we asked them a base set of questions, and asked follow up questions based on the discussion. There were a lot of interesting patterns and ideas that emerged from our conversations:

Having a community is key

  • Most mappers want to map what they know and are concerned about what is nearby to them. This seemed to outweigh the desire to contribute to humanitarian efforts, although that did make mappers feel as if they were doing something good.
  • New mappers often learn more quickly when they have a community, than they would otherwise. Being a part of the community is a huge motivator for people to map.
  • Having someone who can give feedback and make mappers feel welcome increases retention.

Understanding completeness and complexity drives motivation

  • Community feedback and support motivates a lot of mappers.
  • Completeness is a huge driver for many mappers. Knowing what is new and what needs to be mapped, helps them to map more.
  • Understanding, very clearly, how a task is going to help people. Mappers who were involved in humanitarian mapping often didn’t know what the purpose of the task was, which made them significantly less motivated.
  • Communicating the complexity of a task helps mappers better choose a task that fits their skill level. Knowing that a task takes 10 mins or otherwise, is extremely valuable to guide mapping efforts. The skill level of the mappers and the density of the area that is being mapped should be thoroughly considered.
  • Completing a task in 10 mins or less. When tasks are only 10 minutes long, mappers often complete more tasks than they would otherwise.
  • Many mappers talked about not having a good way to see what is unmapped, especially when they’re away from their computers. Not having an easy way to see this information hurts their ability to collect that data when they’re outside of their homes, in their local communities, or are out in the field.

Better onboarding and guides help new mappers

  • Many interviewees commented on how new mappers often don’t understand what OSM is or what it can do. To increase their understanding, more experienced mappers often point them to local communities, the wiki, walkthroughs and most importantly, applications. All of these things are hard to come across or know how to access from the homepage.
  • Adding metadata is a challenge for new mappers. iD’s interface for presets leaves users confused and often leads them select the wrong attribute. Improving autocomplete search and reimagining how new mappers interact with this complicated subject would help.
  • Many mappers are using a trackpad to map and not a mouse, so they often don’t notice the right click features.
  • People learn better by doing. Giving them a way to do this will increase their knowledge.

Being able to easily understand and discover local standards will improve quality

Communities often have their own standards or features that are unique to an area. People who aren’t engaged in the local communities, who don't know what these derivations are, can sometimes do more harm that good. It would be ideal to be able to showcase those local variations so that mappers are more aware of them.

Learning about other mappers helps coordination

Many interviewees commented on how it would be nice to know more information about a mapper. For example, what kind of skills they have, features they’re interested in mapping, potentially how responsive they are to messages. Knowing more information about a mapper could help better build a community, giving people a better understanding of which individuals to reach out to.

Improving offline OSM capabilities will reach new users

Many people in the field or people who often don’t have good wifi connections talked about this. One OSM member commented on how it’s been hard building the community without a way to demo OSM offline.

Other ideas

  • There is a need for an easier and better Overpass, or alternatives.
  • Creating a better building tool for iD.
  • Improve tools to align imagery faster.
  • Better ways to deal with multi-polygon relationships.
  • Being able to have more layers in OSM

Conclusions Per Audience

Another interesting way to look at the data collected is by the different audiences.

People or organisations who use OSM data

  • They want easier ways to import large amounts of information
  • Ways to filter down data - see features that are relevant to them in certain areas
  • Easier ways to export data
  • Being able to map things that don’t belong on OSM, e.g. minefields

People who manage teams of mappers

  • Their wants are mainly focused around getting a better overview of what mappers are doing. Also, being able to show progress in what they’re doing. They want things like:
  • Dashboards
    • Leaderboards (e.g. features in Missing Maps)
    • Being able to see who’s mapping where
    • Seeing change over time
  • Easier ways to get new mappers up to speed so that there are fewer errors

Experienced Mappers

  • Better community
  • Being able to know what is missing or what has changed in their neighborhoods/areas they map
  • Better information in one place. There is a need for more user friendly information on OSM intricacies, and complex tasks such as mapping cycleways.

New Mappers

  • Better tools to help them understand the OSM ecosystem
    • Better way of tagging
    • Better access to lists of resources
    • Better understanding of how HOT and OSM work together (for new mappers there seems to be much confusion over the interaction between the two tabs. They will often close Tasking Manager which obviously creates much more work for them when they’ve completed a task).
    • Better tutorials (Shorter so that they can learn a little bit at a time and/or more easily rewatch a video around a particular topic when they’re confronted with that topic).
    • Encouragement
    • Better community (less intimidating and having a better understanding of how to access the community)

Overall, there is a lot of good potential work here. At Development Seed, our next steps will be coming up with potential projects that fit the needs of the community, as outlined above. Of course, we’d love to hear any suggestions for how to keep in contact with the community or any thoughts about projects to improve OSM moving forward.
