I have very nice results with sqlite+GRASS.
Pablo, I've been using SQLite for several years; it's the back end to my approximate reasoning model for environmental impact assessments.
First, use an sqlite administrator software to make things easier.
I'm a CLI guy and prefer working by typing.
One database for each LOCATION, one table for each vector.
That's what I thought. Thanks for confirming.
One way of working is that You can put rivers, highways, power lines, etc. in the same "layer" and put a column in the table that describe what kind of object it is. You can play with CAT number too, like rivers is cat number x and highways is cat number y.
I'll need to think about this. Right now I have three locations, based on regional extent. Most layers are for the entire state, the DEM is for the northwest portion of the state and the soils are for a single county.
Try no to think as the obsolete shapefile style gis.
I've never used ARC/View. I did use ARC/Info on the Prime in the late 1980s, and a bit of ARC/Info-PC in the same period. Most of the mapping I did in the 1990s was with MapInfo running under VMware on a linux host. I last upgraded that in 1996. :-) Haven't done any GIS work for about 6 years.
I am a agronomist engineer an I have made soil maps and soil use maps with grass, just ask if you have more questions.
And I'm a stream ecologist/fluvial geomorphologist so I'm sure I'll have questions about antecedent soild moisture for the model I'm working toward building.
