It seems that there has been some limited work in transfering files to and from
Grass/Genamap.
Most noteably
anabel@tilo.datsi.fi.upm.es (Anabel Donadios and Alberto Buendia)
jhartman@scanner.frw.uva.nl (Jan Hartmann)
Though we haven't been able to procure any code as yet.
So we here at CSU tried exporting in dlg format from Genamap5.1 and
importing dlg into Grass4.0, but ended up with the following error message when
using v.import:
--------------------------------------------------------------------------
----- PHASE 1 -----> Convert ascii dlg file to binary dlg file.
ERROR: Number of sides in the polygon defining the coverage
of the map less than 4.
63500005007D+00 4 0 4 1 0.147000000000000D+09 0.3600000
Another words the Dlg header is incorrect.
Dlg header line 4, data element 8.
ERROR(v.import): Could not convert ascii dlg file: '/gis_disk/data/grassdata/jarvis/PERMANENT/dlg/cont.dlg.EE' to binary dlg file: '/gis_disk/data/grassdata/jarvis/PERMANENT/bdlg/cont.dlg.EE'
----------------------------------------------------------------------------
The header of the dlg import file looks like this:

Can anyone shed some light on this.
