>I've been using MS Mappoint with a gps device (delorme earthmate) and I've noticed that I get totally different lat/lon coordinates if I read the data from within VFP vs Mappoint. Do you have to do any corrections to the data once it comes in raw? The differences aren't great, but they are significant. Sitting here in my car, I'm gettin a coordinate of lat 35.171598 and lon of -089.404254 via vfp and just reading the port. In mappoint I get 35.28500 and 89.67378. Any ideas?


Calibrate the GPS reader?
