I just wanted to share with you that I’ve been using Mapillary for a few days now with good results. I’ve been using my Galaxy S3/S4 for this but I am thinking of investing in a Garmin Virb Elite just for the task. There’s a pretty good introduction given at SOTM at https://www.youtube.com/watch?v=fvQ1TAIN8rE and you can see one of my capture sessions at Lumpini Park as an example here.
OSM was approved as an organization for this years Google Summer of Code.
In case you are a student or know a student who likes to work on an mapillary integration into JOSM now is a good time to apply for it. Google will pay a stipend of USD 5500.
