Well, I let Windows developers lurking here answer if they have some good
advice. I imagine you would need binaries with debugging symbols to be able to
get a usef

Hi Even, and many thanks! Your pointers have solved my question.
As for the problem building overviews it seems that it occurs when you enter a
tag pointing to a "regular" image, that doesn't have the
INTERNAL_MASK_FLAGS_# set.
On the other hand these flags allowed me to create a mask file eve

Hi Even,
Thank you, in fact it seems clear according to your RPF Spec analysis that the
A.TOC file is not corrcetly formatted.
The TOC file has been provided by Data producer...
As you say the solution is to define another boundary rectangle with the same
coordinate, and it will be ok.
Thank
Hello all
I'm currently trying to do the following, using gdal:
1) Combining some tifs into one using gdal_merge, COMPRESS=LZW
2) Using gdalwarp with cutline to cut out a certain piece of the result
3) Compressing again using gdalwarp, COMPRESS=LZW
4) Generating pyramids with gdaladdo

Even,
No not an i386... A Dell Precision T3500 w/Intel W3680 @ 3.33GHhz 6x2 cores
with 12.0GB. Thought the data is on the network, not local, with 1Gbps access.
The GDAL_DISABLE_READDIR_ON_OPEN = TRUE did significantly increase the speed.
Does the BIL driver read the whole file into memory

I didn't imply that you had to bear poor performance. For higher performance,
other protocols, tile-oriented and cache friendly, are more appropriate such as
WMTS, TMS.

Hi Andreas,
The fact is that I can't use the GDAL API to get the different sub-datasets in
this particular case, so can't make any combination of frames without going
directly to all NITF frames as suggested by Even.
Regarding your answer, maybe the meaning of Zone and Scale is not clear for me
Unfortunately. Even, 'that's life' in my customers world was too slow.
Now I understand what the WMS driver is doing in terms of BlockSize and
DataWindow, I can work round the issue for the time being by requesting a
data window sized block in a single request rather than lots of smaller
blocks in

Hi
A RPF structure (CADRG, CIB, ECRG etc) may include any combination of
scalelevels and/or geographic zones as referenced in the A.TOC file. So
there may be both scale-overlaps and zone-overlaps.
There is also a frame-based update concept but this is seldom used.
An example from a CADRG datas
