[postgis-users] WKT Raster Error

[Pierre Racine]

I already saw the two first lines:

c:\wktraster_pg84\bin\gdal2wktraster.py:645: DeprecationWarning: integer argumen
t expected, got float
  hexstr = binascii.hexlify(struct.pack(fmt_little, data)).upper()

But it didn't not prevent the script to create the sql file properly.

I guess this is related to the Numpy version. Maybe try to use an older version.

It should work with the pipe.

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:
