[GRASS-user] visualising high latitude regions

GRASS GRASS user

Hi all,

is there a way in GRASS to draw latlong projection data with a non-straight coordinate grid? Something like this: <http://www.lib.utexas.edu/maps/americas/chile.gif&gt;

Particularly for high latitudes such as Patagonia, a straight grid gives a lot of distortion.

Any suggestions to do this in other software are welcome. I even don't know if ArcGIS does this.

thanks
wouter

Answer to my own question:

- have your data in UTM
- make a grid in a latlong location with v.mkgrid
- reproject the grid to your UTM location with v.proj
- visualise the grid over your data of interest
- add labels with the latlong coordinates

cheers
