[GRASSLIST:3704] Re: Newbie question from a mac user.

[Ian Macmillan]

I can't answer all your questions, but here are some tips.

1. Make sure your region is set to your raster area.  Try

g.region rast=your_raster_map
d.rast your_raster_map

This can also be done from the pull down menus (GIS? > manage region)

2. Are you trying to make vectors out of topo lines or something similar?  Try
v.digit I think.

3. Don't know, sorry

4. This is a link with some basic maps
http://goasia.about.com/od/nepalmapsgeography/
the USGS seamless server might have a DEM of Nepal too, use Netscape 7 or above
here
http://seamless.usgs.gov

Good luck,
Ian
