hey QJ,
Dumb question time.

Can GPS receivers, or maybe GPS software on a computer take input, not from a keyboard or mouse but from a separately running application ?   We have an experiment that generates data from environmental sensors submerged in water behind a moving boat and would like to display the produced data on a GPS map in real-time.   The env data includes water temp, dissolved oxygen, ph, methane levels,  etc.     Thanks QJ, and as always thanks to DB for the great site.    --paw
