+====== GPX to SHP ======
+===== Summary =====
+This document outlines the procedure to use handheld GPS data in any GIS software.
+===== Prerequisites =====
+==== Hardware ====
+  * GPS unit
+  * cable to transfer GPS data to and from PC (serial/usb, or possibly bluetooth)
+==== Mac ====
+  * LoadMyTracks
+    * http://www.cluetrust.com/LoadMyTracks.html
+  * gpx2shp
+    * http://gpx2shp.sourceforge.jp/
+    * w/ proj4, expat, gpsbabel, libusb, and possibly more
+    * gpx2shp must be built from source on the Mac (nothing tricky, just have required libraries installed and use the --prefix=/sw option)
+==== PC ====
+  * FIXME
+===== Procedure =====
+  - (Field) use GPS unit to create waypoints, tracks, or routes in the field
+  - connect the GPS unit to a computer, and download the waypoints, tracks, or routes
+    - (Mac) LoadMyTracks was used
+    - (Mac) MacGPSPro should work, as well as any other that will create .gpx files
+    - (PC) FIXME ?
+  - once .gpx files are created, use the gpx2shp command line utility to create the .shp files:
+    * **we use the --stats flag to show statistics, and the --fast flag because our .gpx output did not include times so speed cannot be calculated**<code>
+$ gpx2shp --stats --fast Track-2007-04-22\ 23\ 35\ 18.gpx
+Track Points:
+        track count:    1
+        point count:    53
+Routes:
+        route count:    0
+        point count:    0
+Waypoints:
+        point count:    0
+$ ls

+</code>
+  - the .shp files may now be used in any GIS program, such as QGIS, AutoCad Map, MapServer, etc...
