Free GPS Software

I created a map of the Netherlands for Magellan eXplorist and Triton GPS handheld devices based on OpenStreetMap data. If you find mistakes, they are most likely due to problems in the original OpenStreetMap data such as polygons with holes (which in case of water polygons will appear to be flooded), in that case fix it in the data directly and the next version of the map will be corrected. If you find things that are missing, also correct it in OpenStreetMap directly.
