Point Maps April 2016

76 Go Cassandra Maps

Custom tile server for rendering millions of points on a map efficiently.

I wrote this as a learning exercise for dealing with huge amounts of data on a map.

The points are stored in Cassandra, where they are clustered by their tile coordinates at a predefined map zoom level. When a tile is requested, the tile server can then quickly fetch the correct points. The points are then rendered onto the tile in a way that looks nice but is very performant. The tile server also caches the tiles on disk.
