GPS API


Recommended Posts

Posted

Anybody know of any free api's for handling gps coordinates. Hopefully it would include calls for parsing coords and determining the distance between two sets of coords. Just thought I'd ask before I roll my own. icon_cool.gif

There are a number of free projection libraries floating around, like PROJ4. In addition to datum conversions, several do distance calculations as well.

 

As for basic parsing (ddd.ddd, d mm.mmm, dms, etc.) I'm not aware of anything, but that is usually pretty minimal code.

 

Good Luck,

I did find the gfc (Geo-something Foundation Classes). It looked promising but it took me less time to write what I needed ( in PHP no less ) than to cipher out the classes. Thanks anyhow.
