[mapserver-users] Raster Data from PostGIS

[Carlos Ruiz]

Florencia,

As far as I know, Mapserver only works with vectorial data on PostGIS. So having 
a kind of BLOB (bytea)
column doesn't work.

I guess you will have to had those TIF files as a file to be able to load it 
using a RASTER layer.

Cheers from México

Hi,

I have my data rasters (tif files) into my PostGIS database such as file. 
Any file into database is in "bytea" format.
I want to show this raster layer from PostGIS with mapserver. My "Raster
Table" structure and my .map code are:

TABLE rasters (
  id serial NOT NULL,
  nombre character varying(100),
  archivo_bytea bytea,
  mime character varying(100),
  size double precision
)

LAYER
            NAME 'Raster'
        TYPE RASTER
        CONNECTIONTYPE postgis
        CONNECTION "user=postgres password=... dbname=... host=..."
        DATA "bytea FROM rasters"
        STATUS OFF
        OFFSITE 0 0 0
        TRANSPARENCY 100
END

Thanks a lot.
Regards.
Florencia
