Stumbled upon an error in reprojecting data from 900913 (Google Speherical Mercator) to 4326 (WGS84). I’m recalling this from my head now, the error was something related to “NAD sth”. Workaround was to convert it as follows:

  1. 900913
  2. 32650 (UTM for your area)
  3. 4326

I’ll get the SQL from my ofcmate and paste it here…
