[Gvsig_english] Loading DEM data - Beginner

[feraltek]

A beginner question -
I have DEM data files with lat/lon in decimal degrees, and height in meters,
but can't figure how to load them - using the latest gvSig 1.10. It might be
due to the file extensions not being visible to the AddLayers file selector. 

The Geosciences Australia DEM data is in two formats -
1 - lat/lon, height on each line, file extension '*.xyz'.
2 - grid data with a few header lines for cols, rows, corner lat/lon, &
cellsize, then a grid of height data - file extension '*.grd'.

Maybe all I need to do is rename the files with a different extension.
