I did post nothing because I have to better check what is going on with my
project. No time for doing that right now.
I launched my configure script in the same way, but probably something is
missing in my configure.ac.
Could you please post your configure.ac?
Thanks

Thank you so much!
At the moment it doesn't work to me, even specifing the --with-gdal flag in
configure launch.
I'm not an autotools expert, but this is a very good starting point.
If I have time to study and modify your code I will let you know.
Regards.

Compiling my gdal programs with the autotools, I would like to use
gdal-config in my configure.ac file, in order to manage gdal path on
different systems.
The same things is made for example with the PKG_CHECK_MODULES macro for
libraries which support pkg-config.
Is there a pre built macro to do
I solved with the following steps:
1 - right click on project name in "Property Manager" window;
2 - click on properties;
3 - go to Configuration Properties --> Linker --> Input --> Additional
Dependencies;
4 - Add gdal_i.lib (which should be installed by nmake into $GDAL_HOME\lib)
Now the linkin

I think gdal merge is the easier way.
But with a command like this:
gdal_merge.py -of GTiff -separate -o cropped.tif orig.tif mask.tif
I obtainn a GEOTiff with two bands: the first is the original image and the
second is the mask.
This is not what I want.
I would like to obtain a single band GEO
Hi everyone.
Is there a way to crop a GEOTiff image using a Mask of the same dimension?
For example, a mask with a filled circle: every pixel inside the circle is 1
and the others are 0.
I would like to obtain a new GEOTiff with only the pixel inside the circle
visible and the other set to 0.

Very interesting...

Ok. So if I have well understood the most safe thing to do is the following:
myDataset = (GDALDataset *) GDALOpen( "myFile.tif", GA_ReadOnly );
if(myDataset == NULL )
{
return 14;
}
Indeed it works and I obtain 14 as returning value of my program...

I have this incorrect code:
try

}

Hi everyone.
gdal_translate -mo "VALUE=1234" input.tif output.tif
works fine.
But what if I have to insert 2 or more metadata values?
gdal_translate -mo "VALUE_1=1234" -mo "VALUE_2=5678" input.tif output.tif
It doesn't work.
Is there any wildcard to use into -mo string to insert multiple values?
I have the correct georef in the first image and the wrong in the second.
I would like to copy the georef of the first into the second.
I will try mogrify, but I think that the easier way is to create a C program
as suggested above by Giacomo.

My files have both the georeferentiation, but one is correct and the other
one is wrong.
And the georeferentiation is INSIDE the geotiff file, not in a separated
.tfw file.
I would like to obtain only one file as output. To have only one GEOTiff
image with the corrected georef...

Thank you everyone.
I thought it was simpler.
@Ralf Suhr-3
I have produced the ftw file as you suggested:
10.00
0.00
0.00
-10.00
584018.562500
5147058.50
but why the values are different from gda
It is the same, but the georef information is a little bit shifted.
So I have to copy the first georef into the second image.

My case is the first one: with gdalinfo on one of my images I obtain:
Driver: GTiff/GeoTIFF
Files: AVN_CLS57_ALAV2A127252720_20080614_20100906.tif
Size is 8505, 8378
Coordinate System is:
PROJCS["WGS 84 / UTM zone 31N",
GEOGCS["WGS 84",
DATUM["WGS_1984",
SPHEROID["WGS 84",6
One simple question:
I have two identical images, exept for their their georeferentiation. They
represent the same scene, their sizes are identical, but one of them has a
correct UTM georeferentiation and the second one hasn't.
In which way can I copy and paste the correct georeferentiation from
Well ok, but I don't have to merely copy the dataset.
I have to eleborate it and after the elaboration I have to add all the
information i can get from gdalinfo.
So CreateCopy() doesn't fit for me.
How to extrac ONLY these info and put them inside the new dataset?

I saw that this thread is quite old...it is anything changed with the last
version of GDAL?
Is the triangulation not implemented yet?
Thanks in advance.

I have implemented in C++ an example of color table applied to a band, taking
as reference the python script reported in this thread:
