[Mapserver-users] Error message using PostGis

[Zamil Murji]

I wonder if it is a connection issue? Are you getting any connection errors on your postgis layers. One thing I found was that if my mapserver server ip wasn't in the pg_hba.conf file then the postgis layer would refuse a connection to it. More info might be available in your web server's error logs because for a while mapserver was eating up the error messages that might occure below what you read on the screen.

Hi Zamil.

I included the line and returned the same message.

===>> DATA "the_geom from cidade_p using srid = -1"

Thanks.

Hi Gabriel,

I had a similar problem not to long ago. You need to be add USING SRID = -1
to the end of your DATA tag. I'm not to sure if it will accept -1 so you
might have to update the SRID field for every geom to a valid one. Hope this
helps.

Thanks
Zamil

Hi listers.

Is the first time I'm use Postgres/Posgis with MapServer and receive this
error MSG:

==>>       msDrawMap(): Image handling error. Failed to draw layer named
'cidadept0'.

But the original shp file are read without error.

Complementary information:

Postgres/Postgis is: VERSION: 0.7.5 (2003/04/08)

MapServer is:
MapServer version 4.0-beta1 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP
SUPPORTS=PROJ SUPPORTS=FREETYPE SUPPORTS=WMS_SERVER INPUT=TIFF INPUT=EPPL7
INPUT=JPEG INPUT=POSTGIS INPUT=OGR INPUT=GDAL INPUT=SHAPEFILE

MAP file:
 CONNECTION "user=postgres password=xxx dbname=mapserver host=xxxx"
 DATA "the_geom from cidade_p"


I import shp files with:
$ shp2pgsql -d ../mapserver/data/cidade_p cidade_p mapserver|psql -d
mapserver (point data)
$ shp2pgsql ../mapserver/data/politico2001 sc2001 mapserver |psql -d
mapserver (polygon data)
$ shp2pgsql -d ../mapserver/data/politico2001 sc2001 mapserver |psql -d
mapserver (polygon data)
