[postgis-users] WKT Raster Error

[Paragon Corporation]

Andreas,
Nope haven't seen that error before.
 
I take it this used to work for you - gdal2wtraster.py.
 
Which version of gdal are you running under python?
 
FWIW -- we don't run it like that -- we run with the -o output file swithin.
I'm not sure the way you are running it works or not
 
So try
c:\Python25\python c:\wktraster_pg84\bin\gdal2wktraster.py -r
c:\prio_grid\source\forest\fcworld.img -t forest -s 4326 -I  -o
C:\prio_grid\source\gpw\forest.sql
 
and see if you have any better luck.
 
Alternatively you can try the new postgis raster packaged with PostGIS 2.0
and use the gdal2raster.py.  It has some minor fixes in it.
 
Although its in 2.0, at the moment the rtpostgis*.dll is still a separate
binary and doesn't YET have any direct dependency on postgis-2.0.dll (and
has a few more functions that the old wktraster project is missing. So you
can grab it from there and use with your PostGIS 1.5/1.4  or whatever
install.
 
This MAY CHANGE when PostGIS 2.0 finally comes out.
 
We'll also be releasing a new windows binaries of PostGIS 2.0 in the next
day or so.  The dll in that build will change from rtpostgis.dll to
rtpostgis-2.0.dll, but will still be pretty much the same functionality.

Anyone familiar with the below error? 
I have never experienced it before when importing rasters:
