Folks,
gdal-dev has grown to more than 10 mails per day. There are a lot of
mails about using gdal (often programming questions but still just using
gdal through one of the APIs). I propose to split this list into
gdal-dev (for mails that relate to development of and bugs in gdal) and
gdal-users.
Thanks for the reply. I was wonder what the deal is with the other
warnings:

The types in the OGR C api pretty much end in H.
OGRCoordinateTransformation ctrans;
should read
OGRCoordinateTransformationH ctrans;
The function your looking for is OCTNewCoordinateTransformation().

I'll try reviewing and commiting your changes. From a first look, they are
quite substantial/non trivial. Am I wrong if I say they belong more to the
enhancement category than to the bugfix one ? (I assume writing TEXT and CGM

Adam,
I am by no means a gdal_translate expert but I do have experience with
ArcGIS, so I can offer a few comments.
ArcInfo ASCII Grid format does not include a specification of the bit depth,
or even whether the file contains integers or floats. When ArcGIS reads the
file, it infers all of this

Bill,
It may be necessary to create an intermediate file that supports creation (I
think the (rw+) flag on gdalinfo --formats shows which formats support
create, AAIGrid supports CreateCopy() but not Create()). Use gdalwarp to
make a vrt file, then translate the file to AAIGrid:
/usr/local/gdal/
Frank & Mike,
THANK YOU! I apologize if I repeated a question previously posted. I did
quite a bit of searching, and was still having trouble coming up with
exactly what gdalwarp was looking for.
I don't actually have a geotiff from the vendor - I just have a basic JPEG

Hello,
Thanks for responding. When I use gdalinfo --formats, I see that AAIGrid
is included in the list of acceptable formats. However, when I use

I am attempting to take a series of rasters in 32 bit GTiff and use

For Google Earth output (rather than Google Maps which would be in "google
mercator") the output projection should be EPSG:4326, or WGS1984 Latitude
Longitude.

This is my first post here, but have followed the list for several

Try the GDALDataset::GetGeoTransform() and the
GDALDataset::GetProjectionRef() functions on the subdataset.
Here is some sample code:

hi,all
I have a problem when I use the gdal to open the modis Hdf4 file.
when I get the latitude and the Longitude, I do not know how to read it.
is it use GetMetadata( "SUBDATASETS" )?
but the SUBDATASETS, don't include the geolocation information.
in the hdf4 file, ther is a geolocation fiel
