non geoscience application?

GRASS GRASS user
1

I have a question.

Would it be possible to represent non-geospatial data
using grass or nviz?
I was approached by a student with a table of the
local star group, who wanted to see if grass could represent
them (using a greatly exagerrated scale).

Any pointers on where to start would be appreciated.

Richard,
GRASS can be used with any gridded data, i.e., anything that can be
described in terms of x and y values. A non-projected xy GRASS Location
would be used, as with non-georeferenced imagery. I have personally used
GRASS for analyzing occlusal surfaces of molars (teeth!).

Your student might want to look at IRAF, the standard astronomical
software tool on Unix.

For basic astronomical plotting, see pgperl and similar at

IIRC even matlab has some appropriate functionality.
