Triggering events based on GPS location
I am in the process of building my car pc, and I would like to include GPS navigation using one of the better software packages out there. However, I also would like to run a certain exe or macro whenever I am within a short distance from my house, while getting close.
The only way to do this would be by looking at the GPS data and see where I am and see if I am leaving or approaching the house. Is this something some GPS software can do already? If not, would I be forced to chose between GPS nav and that functionality (I will write my own software) or can most GPS units be shared between the several software packages running? Thanks!
