[gdal-dev] Some OGR drivers do not work

Hi, I used the gdal_translate to store the netcdf data into geotiff file, but it just gave me an error: Input file contains subdatasets. Please, select one of them for reading. command: gdal_translate -of GTiff -b 9 -a_srs EPSG:4326 BAND_02.nc /test.tif Does anyone know what is the problem?

[gdal-dev] Problems when mixing https calls

Hi, I've run into problems when I use https calls from two systems (Perl's libww and GDAL) in one program. The use case is WFS with https. First I use Perl like this my $ua = LWP::UserAgent-new; my $response = $ua-get('https://xxx'); (note that the call does not need to be to the actual

Please look at the netcdf docs at [1] When there are various variables in a netcdf ffile, gdal treats them as subdatasets, you can only operate on one at a time. calling gdalinfo on the netcdf file will reveal the special names used to access each subdataset [1]

My question is, is CPL of GDAL doing anything related to OpenSSL (like setting callbacks) No, to the best of my knowledge, there's nothing explicitely related to OpenSSL in CPL use of curl. CPL code sets callbacks, but there are specific to the Curl contexts created by CPL.

Even, Another strange thing with GDAL WFS driver. Earlier it did not try to access the HEAD of a XXX.resolved.gml and now it does: Here's an excerpt from my server logs. These calls are created by GDAL, the first is a good GetFeature call, which gets 215633 bytes of GML and the next is

[gdal-dev] multiple access to a file

2013-05-20 Thread Jose Gomez-Dans
Hi, I have a rather demanding processing scheme (read data from files, and process pixel per pixel). It's trivial to parallelise (just do pixels in different machines/cores), and I intend to run this on several machines on our cluster. I'm unsure whether I can use GDAL (python bindings) like

2013-05-20 Thread Frank Warmerdam
Jose, I'm sorry, but I don't think this will work trivially. If you write a small part of an image, GDAL is likely to read a larger area, update that and write it back. If other programs happen to try and update the same larger area at the same time some data is likely to be lost. If you are
