Polygon data is pre-processed from OpenStreetMap?

[zhenyuan0502]

Hi developers, I'm grateful that the mapit project aggregates polygon data and then could use it in KML files, which I could apply it in my database and push to mobile application to draw it in Google map as well.

I have also walked around the project, but as I see the polygon seems processed from OpenStreetMap database and then stored it on your own database right?

If it is, I just have to ask that what methodology that when you crawl those coordinates, such as here https://www.openstreetmap.org/relation/3819816#map=14/10.7875/106.6956

I just see a very depth nodes to get lat long. This is the way that you guys processing it?

Thank you for replying
