Hi Etienne!
What if you first process the original fine resolution image with a
filter (low-pass, median, or manually created pixel function). Then the
result, which is a fine resolution image but smoothed, could be
resampled with the nearest neighbor.

Hi all,
I am trying to create a raster file with categorical data (land
vegetation/cover positive indices) from a shapefile containing 1 layer of
polygons.
I use the following command:
gdal_rasterize -tr 0.0005 0.0005 -a_nodata -1 -of GTiff -a_srs EPSG:4618 -a
"CLASSE_ID" -ot Byte -init
Hi all,
I am trying to resample a raster with categorical data (land surface
vegetation/cover) from a high resolution (500m) to a coarser resolution.
I would like to do something similar to what the GRASS operator r.resamp.stats
does, using the modal category present in the higher resolutio
I am trying to build a C++ project that uses GDAL in Eclipse IDE C/C++ for
Ubuntu.
I have installed libgdal 1.7.3 provided by Ubuntugis using Synaptics Package
Manager.
I wrote a dummy code to test this installation
#include
#include "gdal_priv.h"
#include "cpl_conv.h" // for C
Balazs,
If you want to programatically perform the actions of gdalwarp, it's best to
go through the code of grapwarp.cpp
http://trac.osgeo.org/gdal/browser/trunk/gdal/apps/gdalwarp.cpp
There are some more test scripts you can refer, if you want to do this
through command line.

Dear list!
How can I use this two bash command with gdal-python bindings?
gdal_translate -of GTiff -a_srs EPSG: -gcp 775 560 20.58329 48.12650
-gcp 9518 539 20.8329 48.12650 -gcp 9525 7136 20.83329 48.00150 -gcp 758

gdalwarp -tps s.tif t.tif

Hi!
Please read these pages of docs written by our programmer who have
installed GDAL with HDF4 support on Windows. They were fastly developed
rather for internal use but you might find them helpful.

Hi, Antonio!
You can do that with the gdalinfo command prior to running a python script:
gdalinfo MODIS_FILE.hdf | grep EV_1KM_RefSB | wc -l
returns a number if subdataset EV_1KM_RefSB exist
return 0 if not.
triton:gdaltest>gdalinfo MYD02QKM.A2010217.1335.005.2010218190207.hdf |
grep EV_1KM_Re
Greetings
I have a Python Script where I call gdalwarp binary (in Windows) to warp
an image. But, before I run the gdalwarp I need to check if the file
exists (DONE) and if a defined HDF layer exists. How can I check, using
gdal, in a Script if a certain layer exists?
THanks
Antonio
