Hello,
I am a developer and new in OSM.
I want to develop a web app which will show a heat map based on distance of OSM elements with some tags.
What is the best way to do it? Which frameworks, tools and which DB’s should I use?
- I do not want to use client side api’s which bring me set of features based on given tags in a given region.
- And If possible I want to use nodejs.
- I tried downloading pbf files and transferring them into MongoDB in GeoJSON format. But it failed because of 2dSphere index’s filtered many features on importing.
Thanks for your help,
