Lindsey and I have recently been encouraging the community to take part in a new campaign where we asked you to verify our automatically detected map objects. The campaign runs until each of the nine tasks receives 10,000 verifications, and the person with the most at the end will win a Mapillary edition of the BlackVue DR900s dashcam.
Why take part?
Verifications help improve the map data that is derived from images in two ways.
- It facilitates human review of AI derived datasets. If we identify 10 street-lights in an area, but only 9 are correct, a verification project allows us to remove that false positive and correct the dataset.
- It helps to train future algorithms that will better detect those street-lights in future. Over time the computer vision team incorporates the data collected from these projects and uses it to improve the performance of recall and accuracy.
The data derived from each image is used by government agencies, NGOs, mapping companies and others. The OpenStreetMap community is also able to download these datasets and add objects like trash cans and bicycle lanes to the map.
So what am I verifying?
Some of the tasks quickly hit 10,000 verifications, but others seem to be a bit trickier. So to help clarify things, here is a guide with a description and images for five of the verification tasks that still have space for people to move up the leaderboards. Remember that for each object, you can click on the image to view the full extent for a better look and more context.
We encourage everyone to participate in the discussion here and to help each other with the tasks. Good luck, verifiers!
Typically a flag made of textile or plastic.
Sewage water drainage, typically with a grid on top or inlet of a curb.
An electrical junction box can contain junctions of electric wires and/or cables.
A receptacle for sending or receiving mail. These can be residential or public.
These access points are smaller than manholes and usually found close to the curb.
