I am working on an application that uses shapefiles as its native data
type. The application supports polygons with holes (for the purpose of
drawing, computing area, finding inside/outside, etc.), but not polygons
with holes with islands, or deeper levels of nesting. This convention of

Yes, polygons can have holes.
I have no idea about q
I think that this is generally call "geotagging" which might help
while looking for options.

GDAL reads EXIF data and you can grab that output and then send it
into an OGR output. I used to have a bash script that did that, but
then I found there were some tricky things to overcome and found that
GpsPrune is really good at this.
GpsPrune can also correlate a GPS track and time stamped ph

I used GDAL to create a new shapefile of polygons.
The polygons (multi-polygons) were land areas. Some of the land areas had
holes defined which were lakes within the land area. Within the lakes there
were some islands of land...so I had a polygon with a hole with more
polygons.

Hi all,
I was wondering if there is a way to get at the original feature id when
executing an SQL query for the SQLite dialect. Something similar to what
is described in http://www.gdal.org/ogr_sql.html for FID for the OGR
dialect.
That is, is there something equivalent to the following for

Hi
I've got some problems with the interlis driver. When I try to convert an
interlis 1 file to shapefiles with the following command:
ogr2ogr shpdir/ 254900/254900.itf,dm01avso24.imd
There are no polygon shapes created. It seems that the point coordinates -
which are stored in two separate colu
Yes. The final effect is the same: photo--> location-->image over the map.

I declare this motion passed with support from TamasS, JukkaR and myself. I
will proceed soon in merging the implementation into trunk.

Is possible to georefence a single point in image?E.g. Action Diagram: 1)
central point (center <-> X,Y) is georeferenced (center <-> lat,lon); 2) an
image loader read center coordinates (lat,lon) 3) the loader place image in
map point (lat,lon).4) result: tag a location with involved screenshot T
Hi Even,
Thanks to the reply.
I did not consider it an underlying Linux Problem, as I was opening
vrts. with 6000+ Files without a Problem.
Thanks for the Info. I will look into having the Limit increased or in
the Long run using the GDALProxyPoolDataset mechanism .
