GPS (Global Positioning System) and related matters

Some of my experiments with GPS:
  • errorplot: graphical estimation of GPS errors
  • Googlemaps: an experiment with the Google Maps API to build a "poor man's GPS"
  • Differences between GPS and GoogleMaps: an attempt to systematically map the differences between coordinates measured by a GPS and those shown on GoogleMaps.
  • Google Maps Errors: some errors and mistakes I've seen on Google Maps
  • GNV RJ/RS POI: POI(point-of-interest) of all GNV (propane) service stations I've encontered in a trip I made in 2008/12 between Niteroi/RJ and Gramado/RS in Brazil
