Archiving old geodata and images

The first map warper application lived on and for a long while it used to run in parallel to the New! Improved! and much faster warper at

Here’s 27K control points that people added around the world on  (There’s over 107K GCPs on – maybe I’ll do another map for that)

I’ve turned off the Rails application and have archived:

  • 5,100 maps metadata in CSV format
  • 27,409 Ground Control Points in CSV format
  • All the clipping masks in GML
  • All the maps source images converted to TIFF format
  • All the maps georectified images in TIFF and PNG formats

Simply pop over to if you want to check them out.
