I have an input dataset like this:Driver: GTiff/GeoTIFF
Files: aot.2007154.0950.geo.tif
Size is 5657, 2287
Coordinate System is:

Alessandro,
Refer to http://www.gdal.org/gdal_tutorial.html for a tutorial on how to do
handle raster data with GDAL.
Look closely at GDALCreateCopy() or GDALDriver::CreateCopy().

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?

The GDALDataSet class has methods to get and set such info. (
http://www.gdal.org/classGDALDataset.html)
The corner coordinates can be obtained using GDALDataset::GetGeoTransform()

hello, everyone.
I need to justify whether one geotiff and one shapefile are in the same
projection with IsSame function from OGR, which will compare the wkt info of
OGRSpatialReference , like below.
bool CompareWktIsUniform(const char* pszWkt1, const char* pszWkt2)

Dear All,
I have an application that has need of the use of an Oracle 'collection'
(aka array) as a column type. The OGR OCI driver does not currently support
this. Would I be better pre-defining the table and then using SQL_Execute to
manipulate the array column or to consider

Hi All,
I'd like to control the order in which overlapping images are displayed in a
mosaic. Is it possible to do that by using a VRT, and altering the order in
which the files are defined in it?
The online doc for gdalbuildvrt states, If there is some amount of spatial

I hope someone has remembered the capability issues concerning WinCE and GDAL
(since its not really being maintained right now). My issue is I am able to
use the provided MSVC++ 2005 gdal project files and build the project to obtain
a gdalce_i.lib and gdalce.dll files.
I created two
Hi,
I am trying to run gdal_polygonize.py and I get the following error:
gdal.Polygonize() not available. You are likely using old gen
bindings or an older version of the next gen bindings.
Anyone have any idea how I can get gdal_polygonize to run within FWTools 2.4.7?
Below is the command and
Hi!
I am trying to print timestamps in WMS driver.
I would like to use GDAL CPLPrintTime to do that.
I searched for use samples and found pcidskdataset.cpp but I don't
understand the magic numbers that appears sztemp + XXX:
Line 1396:
CPLPrintStringFill( szTemp + 384,GDAL: Image band
Hi Frank,
Thanks for the reply. It might be worth keeping the option to control layer
ordering somehow in a mosaic. The reason I'm exploring this is to see if
it's possible to emulate the ArcGIS 10 closest to center behavior. I'm
thinking that if I dynamically write the VRT, I can control how
Hi again!
I found that gdalhttp.cpp logs messages with CPLDebug() function.
Inside that I found that if CPL_TIMESTAMP is set, then a time stamp is also
printed.
But the time does not have milliseconds precision.
Is it possible to change that time format ?
Thanks,
Edu

Eduardo,
In line 1398, 'szTemp + 448' is the pointer to the buffer, '16' is the
maximum length to be written by CPLPrintTime, next is the the format. Don't
bother about the numbers 384, 448, 464, etc.

Hi all,
in my GSoC project [1] I'm trying to employ multithreading to make
rendering in QGIS both faster (on multi-core machines) and more
pleasant to use (not blocking GUI thread while rendering). I've been
successful with making that work in ideal conditions (no concurrent
reads/writes) and now
Martin,
Just a comment. In Geoinformatica, which uses GTK+, I've begun to
address the same kind of problem using the functions provided by GTK+.
So far I've not used this on rendering and I've not thought about all
the consequencies. In some expectedly lengthly GDAL operations it
provides a
