One finding concerning the variable-based pathdefinition to PostgreSQL with schema (thanks to a collegue).
Maybe of interest for other users.

My problems of Raster-import remains open...

Cheers,Patrick

#works
DBPATH="PG:dbname=psql_local"
v.in.ogr input=$DBPATH out=bldg_pt layer=${ISCHEMA}.gws_buildings --overwrite

#does not work
INPATH="PG:dbname=psql_local active_schema=baselayer_2000"
v.in.ogr input=$INPATH out=bldg_pt layer=gws_buildings --overwrite

#work
INPATH="PG:dbname=psql_local active_schema=$ISCHEMA"
v.in.ogr "input=$INPATH" out=bldg_pt layer=gws_buildings --overwrite #NOTE: "in" needs to be quoted or it will not work

Dear list

In addition to my mail yesterday (see below):

The use of PostGIS might be related to the conversation from octobre last year (http://osgeo-org.1560.x6.nabble.com/External-raster-from-PostGIS-td5231932.html), but it remains unclear to me how to import raster and is not referred to in the manual.

My current state seems close to the solution:
r.in.gdal in="PG:dbname=psql_local schema=myschema table=reference_map" out=region_ref -o --o #load into grass r.external source="PG:dbname=psql_local schema=myschema table=reference_map" out=region_ref --o -o #link to grass

But both lead to "ERROR: North must be larger than South"

However, I can view the data in QGIS (loading though db-manager) and it appears to be ok.

Is Error it a problem of gdal, my data or the grass-modules? And how can I solve it?

Thanks for any help
Patrick

Dear list

I need some help on importing PostGIS raster with r.in.gdal and schema support under v.in.ogr.


RASTER:
"r.in.gdal -f" shows support: "PostGISRaster (rw): PostGIS Raster driver"
But I did not find any example on how to formulate the dsn/input.


VECTOR:
Unfortunately there is no hint in the manual of grass70 on how to work with schemas (there was one in 64).
I had a script in grass64 of following syntax, which is still working:

ISCHEMA=baselayer
v.in.ogr dsn="PG:dbname=psql_local active_schema=my_dataschema" layer=gws_buildings --overwrite

However, I would like to form this more general as a variable for all incoming data, which is not working:

INPATH="PG:dbname=psql_local active_schema=my_dataschema"
v.in.ogr in=$INPATH out=bldg_pt layer=gws_buildings --overwrite
=>ERROR: v.in.ogr: Sorry, <active_schema> is not a valid parameter

Also the approach described in the manual of grass64 does not work any longer

db.connect driver=pg database=psql_local schema=my_dataschema
v.in.ogr in=./ out=bldg_pt layer=gws_buildings --overwrite
=>ERROR: Unable to open data source <./>


Thanks for any help,
Patrick
