Hi Frank, all,
Just fyi we had some nitf data that had jp2 blocks with ycc color
space(JP2_sYCC_SPACE=18) . ossim was crashing because the bands were
set to 3 in the nitf but kakadu was expanding only one channel. I
checked gdal and it was returning only one band(no crash). Anyway
feeding
I just tried: If I declare make functions of OGRSFDriverRegistrar as
virtual,
everything is working as expected.
Most of the functions of other classes are virtual, why those are not?
Best Regards,
Mikhail

This is what I normally do, however it's not much less pain, even it's
simple.
I typically write a wrapper to execute all GetProcAdress() functions at
once and store
pointers in the class.
Taking into number of GDAL functions, its' would be very challenging.

Hello List,
I wonder if someone could point me into the right direction. I would
like to use
GDAL as loaded DLL at run time, with LoadLibray() call under windows

I am running Windows 7 and I use the Osgeo4w installer with the advanced

need. The default gdal1.8 is recommended. Osgeo4w can be found here:

Dear all,
I am providing some python/gdal based libraries to Windows 7 users who
are no programmers, so no mingw or VisualStudio is available and I am a

Which of the several should I recommend them to install?

Brilliant ! That works well, and fast. For the record, a command like:
gdal_translate -outsize 3.125% 3.125% .tif _dzm32.tif
serves to extract the 32:1 reduced-resolution level from a file created with a
command like:
gdaladdo -r cubic .tif 2 4 8 16 32 64 128 256

Anita,
Is it possible to send a small sample data to my email for testing? Doesn't
matter if the ID field values are wrong.

Hi,
I used the following ogr2ogr command:
ogr2ogr -sql "select * from nw where NAME = 'Am Johannesberg'" new.shp
nw.shp
The resulting shp contains correct geometries, but the values in ID,N,15,0
fields are broken.
I guess that shows that it's a GDAL/OGR problem.
Thanks, best wishes,

ogr2ogr results in the same broken values. Loo

If so, that would be really helpful. Does anyone know how to extract a single

Anita,
First, let us isolate the source of this error. QGIS or GDAL/OGR.
Use ogr2ogr to clip the part you did with QGIS. See the extents of the
clipped shapefile using ogrinfo and use it with the ogr2ogr utility.

Jay,
The external overview files are created in TIFF format. I checked. However,
most of the metadata will be lost.
You can recover the metadata by using gdal_translate with "-outsize 3.125%
3.125%". It will read the metadata from the original file and the pixels
from the level 32 overview.
