[mapserver-users] GPS to GIS

[Fawcett, David]

I think that the way that you phrased your questions was a little confusing.  'GPS coordinates'  and 'GIS coordinates' are really the same thing.  It sounds more like you want to convert the format that the coordinates are stored in from the one used by your GPS to one that works in a GIS or with MapServer.  

I hacked up a python function to read .gpx files.  I will send it to you off-list.  You could then use it in conjunction with the OGR python module to write a shape file.  

David.

Thanks for your reply.

My intension was to convert CPS-coords to GIS-coords on the fly and for 
that purpose I needed a piece of scripting (an algorithm). But if 
GPSBabel can convert data between these formats, I'll go for that.
