[GRASSLIST:6141] Data Set to promote GRASS

[Hardeep Singh Rai]

I wish to promote and Introduce GRASS to Students of Engineering Collge.
So looking for good presentation on GRASS. Please let me know any good
source for that.

For the same objective, I tried following data sets.

> SPEARFISH for GRASS 5.7

It appers to be working fine, but there is script in this data which may
show full potential od GRASS and this data set.

> Fire simulation data set

There appears to be good script. But on GRASS-Beta2, it gave
"segmentation fault".

> ./firedemo.sh: line 22:  1398 Segmentation fault 

See below signature detail of "log".

I am using it on Debian. Is there problem with GRASS-Beta2 or with
dataset?

Can you suggest any other good dataset or how to remove this
"segmanttation fault"? Or other link to good promotional material.

Thanks for your interest!
Sorry, <nsites> is not a valid parameter

ERROR: Required parameter <n> not set:
    (The number of points to allocate).

Description:
 Creates a raster map layer and vector point map containing randomly
 located
sites.

Usage:

   [vector_output=name]

Flags:
  -q   Run quietly
  -z   Generate sites for category zero also
  -i   Report information about input raster and exit

Parameters:
          input   Name of existing raster map
              n   The number of points to allocate
  raster_output   Name of the output raster map
  vector_output   Name of the output vector points map
