Hello Martin, thank you for the info.

If I've understood the process correctly:
- I use a GPS device, which I instruct where to output its data
- Say I have a server, presumably it ends in a database, which I must design
- I then convert ('parse') the data from the native format of the device to the native format of the mapping system.
- Then I would embed a map into the programme (easy enough, I think) and then by some coding magic, I import the data from the database onto map.

Once I've got to that stage, then I could set up waypoints, such as 'Martin's Town' starting from Lat1-Lat2/ Lon1-Lon2 and any trace within that location could be triggered to say "GPS1 just drove through Martin's Town", for example?


I'm not sure if I mentioned this before (probably) but I originally set out to write some software for a specific task that is badly lacking in my industry; it's not for a commission, it's purely private to prove a point. Most of it is just a basic database anyway, but things like GPS are a bit specialist.

I'll take your offer to show how to parse the data, thank you, but I need to learn a bit more of the basics before I get to that point; I was more interested at this stage to see if it can be done- which it seems it can.

Thanks
Derek
