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.


Pirate Maps December 2015

126 Python Cairo 2D Graphics Maps

Procedurally generated pirate treasure maps. X marks the spot!

This was my submission in the /r/proceduralgeneration monthly challenge. I used several excellent third party libraries...

  • cairo for rendering
  • colour for color interpolation
  • noise for simplex noise
  • Pillow for saving debug images of noise layers
  • pyhull for delaunay triangulation
  • Shapely for all kinds of 2D geometry operations

Mapper August 2015

8 JavaScript Maps

Web app for quickly plotting markers, polylines, polygons, heatmaps, etc. on a map.

Got geocoordinates but don't know how to see them quickly? Just paste them into Mapper! Doesn't matter if it's comma-separated, whitespace-separated, or something else. You can add multiple datasets and each one can be configured to plot different symbols or styles. Once you're happy with the visualization, it even has a button that gives you a link for sharing.
