Yes. Also, most applications I've seen using OGR do define their own
data models and translate OGRFeature to features of their own types.
Perhaps it would be interesting to know why they don't use OGRFeature
as a part of their data model, what's
I was thinking along the same lines, but more in the direction of OGR as
an archival standard. I have been working with archives and stored maps
all my life and am now busy with lots of digital historical maps. For
raster maps the best storing format is Geotiff, from which all other
formats
Jan,
for a vector archival format, surely GML is the nearest equivalent to
Geotiff? That should preserve all information; be vendor neutral; and it be
possible to retrieve all information in the future.

Personally, I find GML far too complex to be of practical use (for my
own purposes, mind). The GML 3.1 specification is 595 pages of small
print, almost none of which are part of existing datasets. I just want
to store existing datasets in a system-independent way, and preferably,
to be able
Hi,
I'm trying to use Gdal in a python program in Win7 (32 bit - portuguese).
I have python 2.6.2 and installed the gdal libraries following the
instructions in this page:
http://pypi.python.org/pypi/GDAL/
That is, I have the GDAL 1.6.1 python extension
(GDAL-1.6.1.win32-py2.6.exe) and installed
I've discovered that when I use OGRSFDriverRegistrar::Open to open a
Shapefile, the file remains locked so that another process can't open the
file until after I've called OGRDataSource::DestroyDataSource. Is there any
way to prevent the file from being locked? Thanks!

I want to convert .tif to .ecw . I use FWtools shell.
Would like to run it in batch so I have following:
for %f in (*.tif) do gdal_translate -of ECW -co TARGET=92 -expand rgb -co
DATUM=RD -co PROJ=DUTCHNEW %f %f.ecw
with result in :
gdal_translate -of ECW -co TARGET=92 -expand rgb -co DATUM=RD
Hi folks!
I published at https://svn.osgeo.org/gdal/sandbox/klokan/ozf/ the
description, sample files and links to existing implementation of the
popular OziExplorers OZF2 and OZFx3 binary formats done by hnedka
user of the Global Mapper Forum.
The description is derived from the code of
Hi list,
I have recently been trying to compile and install 64 bit GRASS7 with 64
bit GDAL1.6.3 on 64 bit Ubuntu 9.10. I have successfully compiled both
packages (with no errors), but am getting this error upon GRASS startup when
the GRASS gui loads and first tries to access GDAL:

hi,
has anyone information if gdal is able to read ACE - Altimeter Corrected
Elevations-DEM-data from ESA?

Helmut,
From the doc, the ACE tiles are just raw files. So this is the perfect
use case for using VRT descriptions for raw files :
http://www.gdal.org/gdal_vrttut.html#gdal_vrttut_vrt
For example, for the 30N000E.ACE file, you can create a 30N000E.VRT
description file

Jan,
I think this is generally impractical with most OGR formats. In
most cases

How do I tell GDAL to set the libtiff warning handler to null?

Richard,
I think you can call gdal.PushErrorHandler( CPLQuietErrorHandler ) to
supress all
Thanks, Frank. I'll check source code of the FalconView Shapefile overlay
and see if it is requesting exclusive access. That could be the problem and
I could change that as there is no need for FalconView to have exclusive
access when it is only reading.

Dear all,
I've been looking around GDAL codebase and I can't see anything that
would deal with wide/multybyte characters for file names/paths on
Windows. Would you please confirm that on Windows GDAL will only be able
to open files with pure ASCII names, not international

One more thing if I may, the Wiki/Roadmap say the RC1 is planned on Dec 15,

I understand the schedule has changed. Would you have new date of RC1?
Mateusz,
I'd like to issue RC1 by January 19th.
Are there things any of the developers are wanting to get in before

Frank and John,
Thanks for the suggestions. I did take the advice to use gdalbuildvrt and then
warp that:
gdalbuildvrt gdalbuildvrt.vrt be44123g8a be44123g8b be44123g8c be44123h7
be44123h8a be44123h8b be44124g1 be44124h1 be45123a7 be45123a8 be45124a1
gdalwarp -t_srs EPSG:2913 -s_srs
