This is a c++ first draft of a port of a perl script by Schuyler to import Garmin gps dump files as a shapefile. The resulting imported file will be displayed in the map view. At the moment it only generates a point layer of the waypoints but a future version will generate polylines and perhaps polygons too using similar logic to that used by Shuylers perl stuff. Note this plugin is still under construction and I am commiting it mainly so that other developers can assist me when I get stuck. Also note that the plugins Makefile builds a standalone app based on the plugin gui that can be run separately from qgis.

* Revision 1.1 2004/03/22 23:38:26 timlinux
41+
* This is a c++ first draft of a port of a perl script by Schuyler to import Garmin gps dump files as a shapefile. The resulting imported file will be displayed in the map view. At the moment it only generates a point layer of the waypoints but a future version will generate polylines and perhaps polygons too using similar logic to that used by Shuylers perl stuff. Note this plugin is still under construction and I am commiting it mainly so that other developers can assist me when I get stuck. Also note that the plugins Makefile builds a standalone app based on the plugin gui that can be run separately from qgis.
