Gary,
what do you mean by 'true north'?
OSGB36 is a Transverse Mercator projection: it is, therefore, automatically
aligned with a (reference) line of longitude, its central meridian. It is not
aligned to magnetic north: those little diagrams on the maps show the offset to
magnetic nor

Matthew,
I am not aware of a utility that reads ascii point data
and directly creates a grid file without any attempt
to interpolate. You could take a couple approaches.
One is to write a script in a language like Python
that will do the task and write the result out to a
GDAL supported grid for

OK - have imported the OSGB36 GEOGCS using the line from the ecw_cs.wkt
file (with first field removed! Oops)
Now I need to transform from OSGB36 to WGS84. I have set up the
OGRSpatialReference of the input using importFromWkt and the output
using setWellKnownGeogCS("WGS84"). The OGR Transform a

anyone give me a clue how to do this? Am I right in thinking that
simply setting the correct s_srs and t_srs would achieve everything I
need? If so - what part

Thanks.
If I build gdal with kadaku will that support it?

Hi,
I just tried downloading and building the latest gdal, version 1.7.0.
I wanted to build it with the new dxf support. The dxf dir is present
in the source tree. While making ogr it enters the dxf dir but does
nothing:
make -C dxf
make[1]: Entering directory `/usr/local/src/gdal-1.7.0/ogr/ogrsf
Hi Vadivelan,
The GDAL build instructions should normally go to
