Hi list,
Premise: I’m tinkering to add support for datasets from multiple sources (like
different subdatasets) in EOxServer (Python, MapScript, …)
Versions: GDAL 1.9.2, MapServer 6.2.2
The sample dataset I try visualize is a MODIS/HDF 4 file with 7+ subdatasets
(see [1] for a description for
Even,
I was not aware that creating a VRT was that easy... shame on me. My
script would have handled connection parameters and created a query
string, but I guess there is not enough added value.
Thanks for the info

Hi folks,
I created a small script that generates VRT files that act as wrappers
to add georeferencing to rasdaman arrays (which do not have this feature).
I thought I could add this somewhere under /swig/python/samples/, or
is this too specific for a certain driver?

Rui,
IMHO point clouds are special form of vector data. But still, an OGR
driver would not be a viable solution.
Did you have a look at PDAL (http://www.pointcloud.org/)? It is
similar to GDAL and seems to have a built-in driver for LAS files.

Devs,
I implemented a couple of improvements of the GDAL rasdaman driver.
Ticket with a detailed description of the changes and patch are
available here: http://trac.osgeo.org/gdal/ticket/5298
Of course, I appreciate any feedback and I hope the
Frank,
I'm assuming you mean gdaladdo is run on y.tif, the output of gdalwarp, right?
Yes, sorry, that's what I meant.
I tried the steps with a manufactured input file of the same size and
did not encounter the problem on my system. The most likely important
difference is that I am not using
Dear devs,
I'm experiencing strange errors when I try to add overviews to specific
GeoTIFF files with internal tiling and LZW compression. This error shows
only on some (about 3-5%) of the input files.
This is how I process the file:
$gdal_translate -gcp 0 0 19.09 49.22 -gcp 100 0 20.1
Dear devs,
I've been tasked to improve or rewrite the current rasdaman driver
implementation as it currently suffers a number of drawbacks:
* it is quite slow (compared to other drivers and other rasdaman
connection techiques)
* it does not support creation of new rasters within the
Hi devs,
Sorry for the noise, I figured it out. Seems like it worked all along
with order 1, but I was just to blind to see.

Hey devs,
I've spent a full day to find a solution to this, but unfortunately was
not able to solve it, so you are my last hope :)
I'm trying to reproject an image with GCPs to a CRS specified by WKT.
I used `gdal.AutoCreateWarpedVRT` to retrieve the output image size +
geotransform in
gdalwarp -order 1 tmp.tif output.tif
Thanks,

Perfect, your workaround works for me.
As I'm mostly dealing with small fairly small images, the performance
decrease may not be a concern for me. I'll stick with this solution
until I can definitely say that the target system has libtiff 4.0.
Thanks Even!

Dear devs,
I'm experiencing an strange issue concerning overviews when I try to add
overviews via Python. Essentially I want to create overviews for
Greyscale images encoded in RGB, but on one overview level I always get
colored pixels in a specific rectangle area of the image.
I created
Thanks for the answer, but unfortunately this does not work on my machine:
from osgeo import gdal
def f(err_class, err_code, msg):
... print err_class, err_code, msg
...
gdal.PushErrorHandler(f)
Traceback (most recent call last):
File stdin, line 1, inmodule

Thanks Even,
I feared that this was the case. But the `UseException` function looks
promising.

Hey folks,
I'd like to know how I could set a custom error handling function in the
GDAL Python bindings?
Currently I was able to turn off error messages like so:
gdal.PushErrorHandler(CPLQuietErrorHandler)
What I want is something like this:
def f(error):

Etienne,
The main advantage of OpenMP is that you can compile the code with
(-fopenmp on gcc) or without OpenMP support but the output *should* stay
the same. So you can produce code that is highly optimized for
multithreaded environments (with little overhead) and still have
backwards
Dear devs,
I'd like to draw attention to a bug in the rasdaman dataset (to be more
specific: its GetGeoTransform method). I created a new ticket [1] and
also added a resolving patch. I hope it will be applied to the trunk soon.
Thanks,
Fabian
