maybe we can check the source codes, and promoted that.
for example: when we get a feature from a layer , not create a new one every
time, just return the same feature, but change the coordinate of features.

In short, you need the full path, and you can't have a slash at the end.
It seems to work OK (so far)

Is there some way to turn off libtiff warning messages generated by GDAL
calls?
How do I tell GDAL to set the libtiff warning handler to null?
using c# gdal wrapper in .NET
Thank you,

Chris,
Here is what the ogr docs say. Look in the directory structure of the VPF
to see what layer names and family names you have:
gltp:[//]//::
Where is the OGDI Layer name, and is one of: "line",
"area", "point", or "text".
Usage example 'ogrinfo':
ogrinfo gltp:/vrf/usr4/mpp1/v0eur/vmapl

I'm trying to use gdal(ogr) to read NGA vector nautical charts, which

I am not aware of Johan, or anyone else, having contributed a WFS driver
to OGR. I do think it would be an interesting thing to have, and I have
contemplated doing one from time to time.

Marco,
You mentioned that you cropped the original image. I guess you left
the meta-data containing the projection info intact. See if you get
the correct locations on the map with the original uncropped image.
Better yet, check the original image using the '-projwin' option in
gdal_translate.

Ragi,
Nicely done. That is pretty funny. I'm sure there's a few others lurking on
the list who have thought of such a thing as well. Could you please send me
the code? Thanks!
Do you know if it would work if invoked from Python-based geoprocessing
tools? We expose a lot of our work to ArcGI
Hello
Was WFS support in OGR implemented?
I can't find any docs about it?

Hi all,
I'm new to gdal tools.
I'm trying to transform a JPEG world image to GeoTiff.
My jpeg world map image is cropped to fit on -180.0, -59.1, 180, 90 (minx,
miny, maxx, maxy - EPSG:4326).
Here are the steps:
% gdal_translate -of GTiff -a_srs EPSG:4326 -co "TILED=YES" -co
"JPEG_QUALITY=100"
