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

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

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
