Update I didn’t get elected, but we have an excellent new board member in Minh. Good luck to the new board!

Hi. Thanks for reading!

tl;dr: I would use my next term to jump-start two permanent OSM US working groups: Growth and Communication. Specifically, I will work with the ED and the rest of the board to recruit 2-4 people for each group and get them started with what they need.

Growth

A new Growth working group will focus on developing and executing new ways to find new mappers, especially from groups not well represented. The OSM US census was a good idea that needs follow up. I feel especially strongly about involving more young people through TeachOSM. And how about an OSM GeoBus? We have a lot of resources ($, ED) and we should put them to use for big ideas that reach new groups of people.

Communication

A new Communication working group will create a deliberate communications strategy. That sounds fluffy but I think it does not need to be. We need to find out who our audiences are and how to bring them a consistent, positive message from OSM US. I don’t want to get ahead of myself, but I suspect that we need hired help with this soon.

The upload scripts are a part of the open source OpenStreetCam platform that are probably not as widely known. You can use them to upload images to OSC that you capture using something other than the Android / iPhone app or a OSC Waylens camera. My colleague Bogdan will publish a blog post going into more technical detail on the ImproveOSM blog soon, but I wanted to share my initial experiences using just the basic uploading functionality.

I don’t want to go into the script setup steps here, but if you are having trouble with that part, I am happy to help out.

Detour: Collecting and preparing my images

If you are just interested in the upload scripts, you can skip this part…

This is the setup I use to collect OSC images when I don’t use the app or the Waylens camera:

tl;dr the release notes 🙂

✨This is a big one✨ We redesigned MapRoulette to make some things easier to find, improve the workflow, and hopefully make it look prettier 💎 as well. We hope you like it!

First of all you will be greeted by a new homepage. This landing page introduces new users to MapRoulette and suggests some challenges to start working on.

Dashboard

An entirely new section of MapRoulette is the Dashboard. This is your personal window into MapRoulette activity. You can see things like your own recent activity, popular challenges and your tracked tasks here. As with almost everyting in MapRoulette, the Dashboard consists of widgets that you can move around, resize, add and delete to create the layout and information display you desire. You can even switch between multiple layouts.

tl;dr the release notes 🙂

If you go to maproulette.org now, you will be greeted with the latest point release: 3.1.3. This is likely the final public release before 3.2, which will be a bigger one featuring a design refresh among other things! For now though, let me summarize the highlights of the 3.1.3 release.

Translations

MapRoulette is now available in Korean, thanks Dongha Hwang!

The Japanese translation was updated to fix minor typos. MapRoulette is now available in 7 languages. If you want to contribute a translation file, have a look at the pull request for the Korean translation to get started. Don’t hesitate to ask if you get stuck!

Task Styling

Thanks to a pull request by Ilya Zverev, MapRoulette now lets you style the appearance of your tasks on the map using the simplestyle standard devised by Mapbox. They have a simple example in their documentation to give you an idea of how to apply styling using simplestyle.

Share your Challenge list

New filters you apply filters to the challenge list to narrow down your results now become part of the URL so you can share that particular list with others. For example, this URL will show you all Challenges that have to do with roads in South Korea: https://maproulette.org/mr3/browse/challenges?challengeSearch=124.28833007812501%2C33.687781758439364%2C132.15454101562503%2C39.6479973237342&keywords=highway&location=withinMapBounds (there are two, and they’re both very useful and fun to work on).

You probably already know that OpenStreetCam detects signs in the U.S. (other regions in development, you can help, we’re open source).

Until now, you would see something like this in JOSM if you enabled the signs layer in OSC

The upcoming new version introduces intelligent aggregation, so you’ll see this instead:

MapRoulette 3.1.1 is now available on maproulette.org. Here’s what’s new!

Mapillary layer

Mapillary images are now available as an overlay on the map. If you’re zoomed in far enough you can select the Mapillary overlay from the Layer dialog.

This is a work in progress. Let us know if you have any suggestions to make it better! And yes, we plan to support OpenStreetCam images soon as well.

Rebuilding Tasks

MapRoulette now supports rebuilding tasks from Overpass based challenges as well as local and remote GeoJSON challenges. You can use the ‘Rebuild’ link at the top of you Challenge maintenance screen to start the process. For Overpass based Challenges, it will simply re-run the Overpass query. For remote GeoJSON files hosted someplace else, it will reload the GeoJSON from there. For local GeoJSON challenges, you will be prompted to select a new GeoJSON file to upload from your computer.

MapRoulette 3.10 is now available on maproulette.org. Here’s what’s new!

For Mappers

We made changes to the map layer selection. You can select more and more relevant background map layers in MapRoulette. The available layers are retrieved from the OSM Editor Layer Index. For aerial imagery layers, you can also select the Mapbox road overlay.

When browsing for Challenges, you can now sort the results different ways: by age, by popularity and ‘smart’ which also takes into account Featured Challenges and Challenges you saved. The old sorting by name is also still available.

TIGER is the street database from the U.S. Census. An old version of TIGER was used to bootstrap OSM in the U.S. back in 2008. We have come a long way since then (see image below) and OSM is now much better than TIGER in most places.

Image from osm.wiki/TIGER_fixup

New versions of TIGER are released every year and they are still useful. Local governments update it with new roads and street names. If you compare new TIGER data with what’s in OSM, you get useful information about where OSM may need improving. If you edit in iD, you get visual cues when roads are missing:

In this post, part of the MapRoulette Insider series, I will show you how to create a MapRoulette Challenge yourself.

The first thing you need is a Challenge idea. Good challenges have tasks that:

• Are easy to solve (typically less than one minute)
• Do not require local knowledge
• Involve only one or two OSM objects

My example challenge meets those criteria. I ask mappers to review motorway_junction nodes in the United States that have name tags. This is uncommon in the U.S. Often mappers will add a name tag that has the destination information on it, so the information renders on the map:

This Overpass query selects all these nodes.

area[name="United States of America"]->.a; node["highway"="motorway_junction"]["name"](area.a); out meta;

This post first appeared on my blog.

A few weeks ago, I built and released Meet Your Mappers, a web tool that lets you identify OpenStreetMap mappers in an ares of your interest. I received a lot of great feedback and encouragement and have addressed some of the main concerns people raised. Here’s an overview of the updates.

Box shaped areas of interest

The single most important piece of feedback I got is that the tool is too hard to use because of the need to identify the area of interest by looking up an OSM relation ID. This is error prone and unfriendly to those not too well acquainted with how administrative areas are mapped in OSM.

This was partly done by design (I didn’t want to make it too easy to use, because of the demands on my bandwidth and the Overpass API) and partly because I was lazy (I didn’t have to build a map widget).

But folks kept asking for it so I added a map widget so you can draw a bounding box to indicate your area of interest. The relation ID option is still there as well.

After introducing MapRoulette 3, the micro-tasking tool for OpenStreetMap, I would like to follow up with a series of ‘Insider’ posts. Each of them will highlight an interesting feature or function of MapRoulette.

This week, we will look at Virtual Challenges.

Challenges in MapRoulette

MapRoulette consists of Challenges, which are groups of similar Tasks. An example is the Embassies missing representing countries Challenge by user johanemilsson. It asks you to add missing country=* tagging to specify which country the embassy, consulate or mission represents.

MapRoulette lets anyone contribute to OpenStreetMap by fixing small mistakes on the map. It works like a roulette wheel: once you select something you want to work on, MapRoulette will give you a random task to work on. Once you fix it, you return to MapRoulette for the next task. Do as few or as many as you like. Be careful, people have been known to get hooked on it!

Since 2013, MapRoulette has been used by thousands of mappers to complete well over 1.5 million small tasks to improve OpenStreetMap. We have put all the feedback we have received and lessons we learned into the latest version: MapRoulette v3.

In a series of posts, I will highlight some great new features of this new version. This is the first post. Enjoy!

Filters

I heard from some mappers that they couldn’t find anything interesting to work on. We spent a lot of time making that easier, by adding different filters.

Location

You can quickly narrow down the list of available Challenges by zooming and panning the map, and selecting ‘Within Map Bounds’ or ‘Intersecting Map Bounds’ from the ‘Location’ dropdown menu. ‘Within Map Bounds’ will only show you Challenges that only have tasks within the current map view. ‘Intersecting Map Bounds’ will also show you Challenges that have some, but not all, their Tasks in the current map view. Additionally, you can narrow down the list to Challenges near your current location. This requires allowing browser access to your location.

A while ago I launched a few challenges on the new MapRoulette (new! you should check it out :)) that have to do with motorway exit information in the United States. Lots of exits around here do not have that information, encoded mainly in destination, destination:ref, destination:to and destination:name tags.

A destination being added based on a Mapillary image

These tags are helpful for navigation users, so they can match what they see on the sign to what they see on their app. Many navigation apps, including OsmAnd, MAPS.ME and Scout use these tags.

Obviously, this information cannot be added from aerial images, but now that there is plenty of street level images from OpenStreetCam / Mapillary to choose from, adding destination info as a non-local mapper becomes much easier. That’s why I created these challenges.

I was going over unnamed ‘main’ roads in my area using this Overpass query in JOSM:

Most of the time I can use the TIGER overlay to add the missing names. Sometimes I stumble upon a way that should have been tagged as a roundabout or a link (and those usually do not have a name tag). There are some cases when a mapper has added a newly built road from survey or aerial images that does not appear on TIGER yet:

The weather is nice and I want to go out mapping a little later. It would be nice to have a file and map with things that I wanted to check. Today I will use Overpass Turbo, a great web interface to the Overpass API that gives you all the tools you need to create a quick Survey Kit that you can take with you: a map you can print, and a GPX file to put on your phone or GPS receiver.

Let’s say I am interested in businesses that have no opening hours so I can go and add those while I am out. This is a query that would give you exactly that. It is probably not complete and could maybe be simpler, but it is quick for small areas and it does what I need :)

I run this query on a commercial / retail area near my house:

I can then export this as a PNG map to print

Telenav created and hosts OpenStreetCam, as many of you know. OpenStreetCam now has well over 130 million images contributed in large part by OSM mappers (thanks!). We already integrate the images themselves with JOSM and iD.

About a year ago, we started an internal initiative to apply machine learning to detect important features such as signs that are captured in the images. While we haven’t rolled that out at scale yet, you can already see the results in some US metro areas such as Salt Lake City, Detroit and Dallas / Fort Worth, using the latest version of the OpenStreetCam JOSM plugin. The goal is to make mapping sign content much easier and quicker. You can, for example, filter speed detected speed limit signs to see only the ones where the way in OSM does not have this speed limit yet.

So far, the technology behind this has been internal to Telenav. This is changing today.

ImproveOSM is my employer Telenav’s effort to process billions of GPS points from our users and partners into actionable tasks for mappers. We currently detect missing turn restrictions, missing or wrong one-ways and missing roads. The easiest way to work on these tasks thus far was to install the JOSM plugin.

Now that we have a new version of MapRoulette, I thought it would be nice to make some of these tasks available through MapRoulette as well. This makes it a bit more manageable, because we have 80.000 missing or wrong one-ways, almost 300.000 missing turn restrictions, and almost 1.6 million missing road tiles.. To break that down, let’s start with a country-by country effort to add missing roads. I created a challenge for Colombia that you can find here. Let me take you through the process of solving a missing roads task. I use JOSM for my example. You can use iD as well, but then you can skip the steps that involve the JOSM plugins.

1. Install the JOSM plugin

If using JOSM, open the plugin preferences and search for ImproveOSM. Install it and restart JOSM. This will give you three map layers for the different types of tasks. I set the opacity for the missing roads layer lower, because the tiles can make it hard to see the imagery.

The Telenav OSM team just released a new version of the OpenStreetCam JOSM plugin. The major new feature is the ability to show and manipulate street sign detections. Images in only a few areas are currently processed for sign detection, so it’s not very likely that you will see anything yet, but that will change over time as we catch up processing over 140 million images.

To enable detections, right-click on the OpenStreetCam layer in the Layers panel, and check ‘Detections’ under ‘Data to display’. You can filter the detections by the following criteria:

Hi all. I want to introduce the new MapRoulette version and invite you to try it. It is currently in beta and feedback and ideas for improvements are very welcome. This information also appears in the wiki section of the MapRoulette GitHub repository. You are welcome to submit issues there. I am looking forward to your feedback!

MapRoulette is a micro-task web tool for OpenStreetMap. It gives you small Tasks you can complete in under a minute to improve OpenStreetMap. Anyone can create groups of tasks, called Challenges, that the community can complete together.

This is the third major version of MapRoulette. The website has been completely redesigned and contains a lot of new features compared to the last major release.
