It might be a little bit of a detour for reaching your goal, but if you're

Hey thanks for the advice, but It seems i'm still having trouble. I have

So I found the inner exception for the All register problem and it says it

Thank you for that, really really thank you.
I'll definitelly give a go.
If u don't mind me asking two questions:
- what do you mean by appropriate parts?
- I have around 3000 files... can I batch it somehow? If so... would you be
able to give me a hint how to do it?

Chaitanya, could you perhaps elaborate on the above statement?
joolek,
About the batch-processing of 3000 files: in my
Linux/Bash/GDAL-from-trunk environment, I would do something like
I'm sorry. I should have said that gdalbuildvrt does not support creation of

Thanks for the clarification and for posting the vrt-lookup-table trick.
This was very helpful.

This *is* the nodata value of ch00_form.tif.
The vrt which I posted has been generated through a simple:
$ gdal_translate -of vrt ch00_form.tif ch00_form.vrt

What is the method for us poor Windows users for getting JP2KAK support

I'll reply to myself in case anyone have the same problem.
Apache is linked to SQLite. SQLite from deb is not compiled with
rtree. WSGI is started as Apache fork, so the process has SQLite (from
/usr/lib/) already loaded and later explicit loading of SQLite lib
with rtree cannot help.
I solved it
I already see a flaw-- the function should be more like:
float GDALSlopeHydroAlg (float* afWin, float fDstNoDataValue, void* pData)
{
// Hydrologic Slope is the max
// local slope btw center cell and adjacent cells
const double radiansToDegrees = 180.0 / M_PI;
GDALSlopeAlgData* p
Apologies for the flurry, one more change:
float GDALSlopeHydroAlg (float* afWin, float fDstNoDataValue, void* pData)
{
// Hydrologic Slope is the max
// local slope btw center cell and adjacent cells
const double radiansToDegrees = 180.0 / M_PI;
GDALSlopeAlgData* psData = (GDALS
