Hi all,
Opening ALOS AVNIR-2 & PRISM (CEOS format) images using GDAL is really
slow and uses loads of memory on Windows XP. This includes things like
gdalinfo and opening via the python bindings (gdal.Open()).
I've tried (on WinXP) with various gdal installs (fwtools, osgeo4w,
basic binaries) and
Selon Joaquim Luis :
Very weird. In such cases, I'd recommand a 'make clean; make', especially if
you've hacked your tree. If it still continues afterwards, you'll have to set a
breakpoint in GDALRasterBand::SetNoDataValue() and see what calls it.

Yes, strange it is. I'm using trunk as well (from yesterday) but I don't get it
when I use FWTools.
Even weirder, I used GTiff just as an easy example but the original place where
I saw it is with my gdalread MEX, which only reads a dataset and does not
attempt
to write it anywhere.
Even Rouau
Selon Joaquim Luis :
I can't reproduce your issue with trunk, nor can I understand how it can happen.
This error message is thrown when a driver doesn't implement the
SetNoDataValue() method. But the GTiff driver has supported it for ages.

Hi,
In this example I get the (apparently innocuous) error message below.
The file is correctly converted, but why is it complaining?
gdal_translate w020n40.Bathymetry.srtm lixo.tiff
ERROR 6: SetNoDataValue() not supported for this dataset.
Input file size is 4800, 6000

The driver doesn't support updating netCDF files. gdalinfo --formats says:
GTiff (rw+): GeoTIFF
(...)
netCDF (rw): Network Common Data Format
The "+" indicates update support, which is obviously missing for netCDF format.

I'd note that in the OGR XPlane driver, a function is available to compute the

Hello everybody,
I have a problem converting a gml file into .shp. I'm using this command:
ogr2ogr -append -f "ESRI Shapefile" limits limits.gml -nlt multipolygon
but it's not working, it seems that only one geometry per feature is converted.
What am I doing wrong?

I'm still fairly new at using GDAL, but I am having trouble burning a
vector image onto a NetCDF file. I've had success with using
gdal_rasterize to burn a vector onto a GeoTIFF file, but when I try to
burn the same vector onto a NetCDF file, I get an error.
Based on the error, I'm suspectin

Rescale the input pixels values from the range src_min to src_max
to the range dst_min to dst_max. If omitted the output range is 0 to

Thanks for your reply.
Would you be able to give me an example of the syntax for the gdal_translate

How do I change the dynamics to 8 bits?

Hi all;
I wanted to compute the distance between two points,
and for this reason I tried the "OGRGeometry::Distance" member function.
However, I saw that this function only returns the linear
distance between the objects, regardless of their geospatial reference.

Thanks a lot. It was indeed enough to put a new dll into FWTools bin directory.

Hi Frank,
thank you for your answer. I have tried
gdalwarp -t_srs EPSG:4326 -tr 0.031156 0.019021 pic_gcp.tif result.tif
but neither with QGis nor with SharpMap the map is rendered undistorted.
And that although the sizes now have proper values...
Any idea?
