Synopsis

I need to transfer data stored in a Delorme "draw" file (extension ".an2") into a usable GIS format. I have a copy of Topo 9.0 available.

Export the AN2 file(s) to AN1 format.

In Topo 9,

  1. click the Draw tab
  2. click File
  3. select the relevant layer
  4. click export
  5. save as an1 file

Use gpsbabel to convert the AN1 file to a usable format, for example KML.

The command line (generated for me by gpsbabelfe) looks like this:

gpsbabel -w -r -i an1,nogc=0,nourl=0 -f /home/bwilson/Topo/cds_6.an1 -o kml,lines=0,points=0,floating=0,extrude=0,track=0,trackdata=0,trackdirection=0,labels=0 -F /home/bwilson/Topo/cds_6.kml
