Hi,

Im Luigi... I need to know if someone have approched the solution I'll write you.

Precondition 1) I've a collection of shape file imported in Postges/PostGIS following OGC rules (e.g imported by shp2pgsql)

Precondition 2) I'm wating better integration with new vector format in GRASS 5.7... but now I've to use 5.0.x, the official release.

What I need:
manage a vector layer extracted by a sql statement.

Guideline (I could follow, and I can imagine)
Query a set of recordds following a sql statement
Save query result somewhere
Import in GRASS ambient managing reprojection

question 1) Someone could help me... knows about similar solution?

question 2) There's already a built-in command that satisfy my needs?

question 3) What's the best way to develope a similar solution?

question 4) What's critical point to be careful developping solution?

question 5) Could be possible apply the above guideline for images and raster also?

Thanks a lot :slight_smile:

1) 5.1/7 can work directly with Postgis lines and points. This is currently slow and
needs improvements.

2) Postgis data can be imported by v.in.ogr.

3) Direct support for OGR data sources (including areas) written by Piero Cavalieri
is available here http://mpa.itc.it/radim/g51/Piero_OGR.tar
