Wow, Looks like a lot of you are clueless about OSM.
Niantic switched from Google map data to OSM map data. When doing this, it left A LOT of areas blank because those areas have never been mapped on OSM. Now autists like --->
>>36481322 see nothing but that light green color everywhere.
Niantic needs to update their data in order to fix this issue. It's super easy too, OSM literally sends out weekly updates to any client which wants it. Nianitc simply decided they'd rather do it randomly on their own instead of having it update weekly/bi-weekly/monthly in the background. Strange. I guess they don't want to risk vandalism in game like PIC RELATED.
