[mapserver-users] How accessing Postgis Raster with MapServer

Tue Mar 13 19:35:23 EDT 2012

Hi Paolo,
thx for hint.

I remove the
ConnectionType 'ogr'

and set the NODATA ans SCALE as suggested in the faq:

    NAME "ofc10k_single"
    STATUS ON
    EXTENT 1559445 4921905 1566395 4927805
    TYPE raster
    DATA "PG:host='localhost' port='22002' dbname='my_database'
user='postgres' password='my_password' schema='my_schema'
table='ofc10k_single_2010' mode='2'"
    PROCESSING "NODATA=0"
    PROCESSING "SCALE=AUTO"

Unfortunately it still don't work correctly.
I set debug to max level and see this error report.

(seem the NODATA=0 was not supported ?)
