Hei,

I’m very new to GRASS GIS and I’ve to make an application that uses it.
I have some questions :

  • how do I represent objects in a map, eg, a car or a plane on a map ?
  • can I associate tabular data with a map in a GRASS DATABASE ? HOW ?
  • Where does PostGIS enter in GRASS GIS databases?

Help would be so appreciated… ^-^

Thanks.

In GIS we have raster or vector representation of object. Each of them
has advantages and disadvantages.

Yes. see v.in.db, v.in.ascii, v.in.ogr for details

- Where does PostGIS enter in GRASS GIS databases?

You do not need to work with PostGIS if do not want to. But you can
access at the data stored in PostGIS using v.external

You can learn a lot from GRASS GIS 6.0 Tutorial. Version 1.2 (see

symbols aka icons, e.g.

d.vect type=point icon=extra/airport
