Heat Maps!


Borne out of the need to get some kind of visual understanding of how GeeOhTileServer is performing/being used, I decided to start implementing heat map images for the various zoom levels.

Aside from indicating any potential issues (because I will be plotting errors/failures also), this will be a great help in identifying general locations of users and getting a literal picture of the overall use of MakingTracksGPS.

It will look damn pretty too 🙂

A few related tasks that I’ll be working on tonight are:

  • Auto-expanding images
    • Re-sizing and re-applying existing data when new data is outside bounds
  • Rendering a grid or some sort of scale indicator
  • Working on JavaScript to dynamically display this in admin page(s)
  • Store update events for the heat maps, and apply them periodically as a batch, in synchronized code block

Watch this space!
