How do I show speed in MPH using my gps track data and Google Maps?
I’d like to see some sort of speed information in my gps track loaded into Google Maps. I can convert to just about any GPS format–currently using *.kml files.
MPH would be the ideal unit.
How far from home can a GPS track?
Buying one for my brother. He works very far from home. Will it help him find his way around work area 30 miles from home?
