Hi,
I'm planning to reproject a Landsat image using gdalwarp but I have a
question:
- Besiodes the 7 bands, I also have an AUX file (for each band), an RRD for
each file and a GCP. Is it possibvle to use gdalwarp to read this GCP file
or is it useless since all the required information is already
Dear gdal'ers
I am working with TRMM rainfall data from an HDF5 file (converted from hdf4 to
hdf5). I am able to use gdal_translate to extract the gridded data from the HDF
file using the following command.
gdal_translate -of GTiff
Thanks Mateusz,
just tested and all works fine

I can understand how the UnionCascade works in PostDIS since it's an aggregate
function. I just don't understand how I should use it in OGR. The documentation
has a single line
UnionCascaded(self) - Geometry
So it returns a geometry from another geometry, but I would need a

I don't know if it works on geometry collection but it certainly works on a
MultiPolygon. In return, you will get either a Polygon or a MultiPolygon
depending on the union being connected or not.

I have updated the Ruby bindings so that they will build against Ruby 1.9 and
the changes are in trunk. I am looking for people to test and give me
feedback. If it works well for people, the changes may make it into a 1.8.x
release.
Details are available at the following URLs:

openjpeg 1.4 released january 2011 provides tile-level reading. Is there
any chance to build the gdal driver with openjpeg 1.4 ?
Many thanks for your help,

Julien,
I've just diff'ed openjpeg.h of 1.3 and 1.4 and couldn't see much difference

In a Python script, I am updating an exiting shapefile with data by
adding a column. However, my changes don't seem to be saved. Here is
what I have:
from osgeo import ogr
obs_file = 'myfile.shp'
source = ogr.Open(obs_file, 1)
layer = source.GetLayer()
layer_defn = layer.GetLayerDefn()
