Hello,
Is it possible to apply an on-the-fly affine transform to an OGR dataset
with the help of VRT ?
Could not find any help or mailing list message about this...
The source of the issue is we want to display in QGIS a
non-georeferenced raster with an associated GML mask, where the

I now recompiled with #define HAVE_LONG_LONG 1 (manually added it to
cpl_config.h) and it seems to work now.
Julien,
I am not aware of any existing way to do this. I might be nice if an OGR
VRT could apply something like this on the fly, but that doesn't exist
currently.
Best regards,

Hi,
This works with ogrinfo
ogrinfo -ro cities.shp -dialect SQLITE -sql select GEOMETRY from cities
I tried to make a VRT file which would do the same

Hi guys,
I'm trying to make a script that converts 3d shapefiles to 2d.
I'm using the loop 'for...do'' and this command:
'ogr2ogr -f ESRI Shapefile -nlt POINT 2d_points/$shp $shp'
My problem is that i don't know how to select only shapefiles of
points, and next only polygons, and next only
If you are using a recent version can you ignore geometry type and use
the -dim 2 switch?
-dim val:(starting with GDAL 1.10) Force the coordinate dimension to
val (valid values are 2 or 3). This affects both the layer geometry
type, and feature geometries.

Jukka,
Agreed! The SrcSQL directive in the VRT should accept a dialect option.
I'll try to do that this afternoon as we are sprinting here at FOSS4G NA
and this would be a nice sized feature to add.
Best regards,

Hi Eli,
Like that?[1]
[1] ogr2ogr -f ESRI Shapefile -dim 2 pontos_2d.shp ocup_ilegal.shp
With this command don't work. I'm using 1.9 version but the '-dim'
option don't show up if i type 'ogr2ogr --long-usage'.

Jukka,
It turns out you can already assign a dialect. I think it is roughly like:
SrcSQL dialect=sqliteSELECT .../SrcSQL
It seems to be touched on it the docs for the OGR VRT driver as well.

Frank

Yes just like this.

It is only in GDAL 1.10+ so it will not work in 1.9.

Hi Frank,
Great, and I guess that this syntax example about how to select the dialect
will be added to the driver manual page http://www.gdal.org/ogr/drv_vrt.html
in your documentation sprint of FOSS4G NA.

Hi everyone,
I have seen crashes in libecwj2 when reading certain JPG2000 files as
well (on Linux). I have tracked it down to the bundled XML-handling
code in libecwj2 but have not had time to fully investigate.
But what I found was that if I turn off optimization when compiling

Hi,
I did see it too but I did not undestand what it means before I saw your
example. XML is not my native language and the meaning of Starting with OGR

Hi,
The -dialect parameter in ogr2ogr does not have an effect when using VRT as
datasource but could it be made to inject the selected dialect into SrcSQL
element of the VRT? Thus
ogr2ogr -dialect SQLITE
would lead to
SrcSQL dialect=sqliteSELECT .../SrcSQL
