Also, use the "-s" switch (in r.to.vect) to get smoothed and not edgy
polygons :-)

Hi,
I am using gdal_merge to merge different rasters. The problem is that the
nodata values appear as black and I want to have them white.
Is there an option to set nodata values to white with gdal_merge? Or would
I have to do this as a postprocessing?
The problem is that the images are too larg

I have been trying to use the OCI driver to create a table and load data
into it. I have been using the same code loop in the past to create
shapefiles without problems. No errors are reported during the
CreateFeature and SetField process based on return status but no data
shows up in the table.
Thanks for having a look at my problem. I am adding more information:
I am merging a number of rgb tiff files (scanned city maps), but they
don't align perfectly at the outer edges. This means that on the edges of
the resulting output file, where the tiff files don't align, I get borders

Bruce,
I have seem this error message before and I think is it exactly what you
though but just for troubleshooting, could you try to re-create the
columns as NUMERIC without (precision,scale) and run it again. That will
point out where the error occurs. Maybe.

Hi Andreas,
If you use gdalwarp rather than gdal_merge you could use the -srcnodata
and -dstnodata flags to change the null value:
gdalwarp in-01.tif in-02.tif outimage.tif -srcnodata 0 -dstnodata 255
This assumes the nodata in all the input images are the identical (0, or
black).
Since

I am currently using GDAL and MrSID DSDK for reading and georeferencing
raster files.
Currently it is using the .aux file for projection information and this
is working fine for .sid and .tiff files.
(I have tried using 1.5.0, 1.5.2 and the current dev branch)
Now it seems like starting with

Any suggestions on where I can find one?

(and I can create a shapefile per topo map too if required). What I

OGC KML allows for styles to be remotely defined within the element,
