Dear Frank and Markus,

We are dealing with geological spatial datasets, which are considered to be handeled with GRASS –GIS.

Some data is already converted into grass vector formats, but as trial the template Spearfish dataset is used – to get familiar with all the ins-and-outs of grass.

Because a considerable task in creating the geological spatial dataset should be done with database routines, we want to have our data implemented in a spatial database.

We recognized the postgreSQL in combination with postGIS as the most reliable database option in combination with GRASS5.0 – the software is installed – but we have problems with the implementation of the data into the database.

Our basic question is this:

*	how can a GRASS-database like Spearfish with its directory structure be implemented into postgreSQL
*	how can GRASS substract / read data from this database.

We don’t know if these questions can be easily answered, possibly a tutorial, or a template spatial postgreSQL would be useful.

Yours sincerely,

Nico Hardebol & Jan Boonen
