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
