Instead of that, pixel geographic position is given in two other HDF5 file

I added a Length() method for geometries into bindings. The method
re-dos a simple euclidean distance as the get_Length of OGR proper is
not exposed.
I hope this is ok. Length is in OGC SF with that name. However, the
standard specifies that the length should be in its associated

Ari,
I'm not clear on why you reimplemented it for the bindings instead of
just exposing it from the core, and

I normally restrain to propose GMT solutions here, but I'll open one
more exception now as this problem seams easy to solve with it and also
because I have o idea how to do it with GDAL.
For this, if your grids are not in netCDF, you will need a GMT built

Hi Luisa,
I've tried something similar in the past with satellite data. I had 3
files, containing latitude, longitude and value stored as floats. I had
some very minor success with the following solution (I got out an image

Many relational databases allow fields to be set to NULL. Is this supported

All fields in OGRFeature are nullable. I think most OGR drivers will support

Jason,
Having (successfully) built abstraction layers in the past to wrap
ArcGIS APIs (aka ArcObjects), OGR (and others) for other projects, I
would strongly advice you *NOT* do it. Why? Because you end up with
some API that looks **way** to similar to ArcObjects or OGR! So why
not use one of

I have been working on this issue for some time and the driver has a quirky
way of handling spatial reference parameters. If a tag is not present, the
netCDFDataset::FetchCopyParms() function returns a default value.
Currently, those default values are all specified as 0.0. Because of

I would hold off on that patch for a little bit, I just found an issue.
I also just replied to the other patch I submitted in trac.

Hey guys.
Does anyone have a good palette for use with gdaldem's colorrelief
mode? I have a tough time with colors, and figure that somebody has
already put together a nice green-brown-white set of colors.
The spatial region is New Zealand, so it's land with surrounding sea, a

Yes. Also, most applications I've seen using OGR do define their own

Perhaps it would be interesting to know why they don't use OGRFeature

Hi folks,
I have a set of PNGs that I would like to add geo-referencing to.
Frankly, I'm not sure what projection they are in, but I do know the
bounding box in lat-long, and I think they are simple geo-coordinates.
I tried adding a *.pgw world file, that looks like this:

Thanks for your thoughts. I know what you are saying; no need to create a
another useless layer. But by adopting one or the other APIs, I would get
locked in to whatever that API decided to support, with no way to work
around it other than to hack on a private copy of that particular API.
Maybe it's just me... but...
I'm trying to connect to another Oracle instance, on a different machine,
