I get customer lat long from an app and my use case is I need to display number of users present in 50m*50m or 100m*100m(deployment time decision) blocks on map.
Some what like below image. No zoom in/zoom out required
So far I have considered MGRS Id (https://en.wikipedia.org/wiki/Military_grid_reference_system)
But It don't provide me 50m*50m block aggregations. Can someone please suggest me some algo by which I can do this aggregations.
