I'm dealing with jpeg2000 images that have 12 bit components and have been
going through the jp2kak Kakadu driver. Earlier versions of this code
truncated my 12 bit values to 8 bits, but the latest code returns all 12
bits to me, but I get my 12 bits in the lower 12 bits of the 16 bit data
value.
O.K.:
The following syntax for a ogr2ogr dbf LEFT JOIN works:
ogr2ogr -sql "SELECT AREASYMBOL, MUKEY, DRCLASSDCD FROM soils LEFT JOIN
'master.dbf'.master ON soils.MUKEY = master.MUKEY" outshpdir soils.shp
Thanks to all for your help in figuring this out.

OK - having messed with GDAL for a couple of days now, I can display
imagery using the GDAL c++ classes to extract raster tiles.
However, I now need to be able to convert xPixel/Line couplets to
geo-positions (UTM, LL or whatever). I have scanned the classes and
have failed to come across a me

Hi,
Is it possible to perform a warp operation on an MEM dataset? And if it
is possible should I just follow the guidelines suggested in the Warp
API tutorial on the GDAL website? The reason why I want to do this is
because recently I have discovered that Read/Write operations to an MEM

Do you know where can I find geotiff images based on EPSG:4326?

I have no luck
Downloaded compiled package form http://vbkto.dyndns.org:1280/sdk/
(MSVC2008 (Win32) -stable, v 1500).
I set the path as described before, that is:

Hi Jorge,
I'm not sure what projection your cea.tif was in (it seems you've not pasted
the full wkt output from gdalinfo on cea.tif?), but you say in your message
