ImproveOSM has been updated with many new roads. We processed recent GPS data from a number of data partners with some great results. A total of 30,000 new missing road tiles were added, over 17000 in Indonesia alone.
Aside from the missing roads, we added 67000 potential missing one-way roads that we detected with high confidence. Internal testing revealed only 6% false positives.
We are happy to continue providing OSM mappers with high quality data about missing things in OSM based on billions of GPS traces. Because ImproveOSM is based on actual drives from people using navigation or mapping software in their vehicles, and we apply a pretty high threshold for number of trips and quality of the GPS data, you can be pretty confident that every ImproveOSM feature will lead you to something you can add to OSM. Even if the aerial imagery is poor.
You should see the new data in your ImproveOSM plugin or on the ImproveOSM web site very shortly. Happy mapping and let us know what you mapped using ImproveOSM!
We added more than 800 thousand new road tiles to ImproveOSM all over the world. The anonymous GPS traces are sourced from INRIX, a company that provides traffic and connected car services. We are extremely excited to have such a huge boost to ImproveOSM and to OSM itself!
If you haven’t tried ImproveOSM recently, why not head over to improve-osm.org right now and explore the millions of missing roads, one-way streets and turn restrictions detected from big data analysis on anonymous GPS traces from drivers all over the world?
With the help of ImproveOSM, Telenav’s project to analyze billions of GPS points to detect missing roads, one-ways, and turn restrictions, you have already looked at 60,000 missing road tiles, 15,000 one-way suggestions, and 2,000 turn restriction suggestions since the project launched in September 2015.
Today, the Telenav OSM team has released a completely new version of the ImproveOSM web site. ImproveOSM.org is now entirely based upon the OpenStreetMap iD editor. The new ImproveOSM combines the benefits of the familiar, user-friendly iD editing environment with the power of ImproveOSM detections.
The new ImproveOSM web site showing missing roads.
Since the new web site is based on iD, it should look very familiar and you should have little trouble getting started with it. The main difference you will see is that the ImproveOSM version of iD has a special panel, which shows ImproveOSM specific options, actions and information. If you have used ImproveOSM before, these will be familiar to you. You can mark items as solved or invalid and apply filters to determine which detections you see.
I do not want to go into too much detail in this post, but I do have a quick power tip: following up on many requests from you, you can now select multiple missing road tiles more easily by pressing shift and selecting one tile. This will automatically select all adjoining tiles within the current view.
Our goal is to integrate the ImproveOSM functionality into the main iD editor over time. To make that happen, your feedback is really important, so please do not hesitate to report bugs and ideas on the project GitHub page, where the source code will also become available soon.
We hope you enjoy the new ImproveOSM web site and look forward to your feedback! Happy mapping!
The team has been working on some nice updates to the ImproveOSM JOSM plugin. I have been taking the new version for a spin and wanted to report back.
In case you need a refresher: ImproveOSM is a suite of tools (currently a web site and a JOSM plugin) that takes the results of a massive data analysis comparing billions of GPS data points with existing OSM data and displays them in a way that makes it easy for any mapper to improve OSM with missing roads, turn restrictions, and one-way tags.
The improvements are fairly small but gave me a noticeably nicer workflow, so I thought it would be worth sharing.
The first improvement is that you can now right-click on any of the ImproveOSM layers in the layer panel to access the data filtering options for that layer.
The data filters let you see part of the data for that layer based on various criteria, such as number of trips, confidence level, status and others. The criteria available vary by layer. Here is the filter window for Missing Roads, for example:
The filters themselves are not new, but you needed to go to the ImproveOSM panel to access them before. I think this is way quicker.
Another thing I really like is the improved visualization for the turn restrictions. The team made it much easier to see the from-via-to flow of the suggested restriction. The from-segment is now green and the to-segment is red. When selected, the info panel will also display more useful information than before:
The detailed info panel was improved for the other categories (missing roads and one-ways) as well.
Finally, when you are done mapping an ImproveOSM thing, you can now quickly mark the thing as invalid or solved, without having to enter a comment. We realized that this was not a very efficient workflow. You can still add a comment upon closing the issue, but now it’s easy to do it without, by right-clicking on the ‘solve’ or ‘invalidate’ buttons and selecting the appropriate action.
These small but meaningful improvements made my work with ImproveOSM in JOSM much more efficient. We are always looking for more ways to make ImproveOSM better. If you have used ImproveOSM and you have a few minutes to spare, I would appreciate it if you filled out this survey. Thanks a lot!
In a new data release today, we added about 500 tiles worth of missing roads in and around Guatemala!
We are excited to be adding more and more Missing Roads data to ImproveOSM using GPS data from our own users as well as from data partners, like we did in Brazil and in this case.
You will notice that the tiles look a little different from the ones you are used to if you have used ImproveOSM before: they don’t show the individual points. This is because this particular data was processed a little differently. If you use JOSM, you will also see an update to the ImproveOSM plugin to accommodate this change.
While you are looking at the new Missing Roads, perhaps you will also notice some other recent improvements to the ImproveOSM web site. We re-ran all tiles based on new map data from mid-April, and we improved our turn restriction detection so we won’t show a missing turn restriction when OSM already has a ‘only straight on’ restriction.
