Thanks Even,
I was trying to overlay the kml on top of my crowdmap which uses OpenStreetMaps
(which is in EPSG 900913 or 3857) as baselayer. When my kml did not appear, I
thought I had to reproject it to the projection of the baselayer..
Looks like the problem lies elsewhere - maybe the ogr2ogr-

Hi all,
I'm having some trouble with a simple conversion from shapefile to kml.
Description
1. I need to have a points file in kml that is is EPSG 3857 (the mercator that
Google uses)
2. I have a points file in both shapefile as well as kml format, in EPSG 4326

Even, thanks for the excellent info. I think we may pursue the first option.
BTW setting the default precision to (for example) 8 instead of 15 would
increase the chance of consecutive identical coordinates in the output string.
Do you think ExportToWKT would be smart enough to condense to a si

Hello list,
Does anyone know of a way to set the numeric precision on a
Geometry.ExportToWKT() call ? For the SRS, we are using EPSG:4326 (WGS-84) so
the multipolygon coordinates are in latitude/longitude, and most of the
coordinate strings seem to carry 15 digits past the decimal point !! F

Mateusz,
The ::Open() method of GDAL drivers is supposed to make all necessary
cleanups, even in case of errors, before returning NULL.

I apologize, I've suscribed to many mailing lists the past days, and I
confused the destination.

Looks to me as if it is a problem with libkml compilation, not GDAL... So a
libkml mailing list might be a better place to ask advice and/or report bugs.

I have this incorrect code:
try
{
myDataset = (GDALDataset *) GDALOpen( "myimg", GA_ReadOnly );
}
catch(int n)
{
cout << "File not existent!" << endl;
return 14;
}
I would like to catch the exception thrown by GDALOpe
Even,
Many thanks for your clear answer that helps the understanding, I will
directly associate an .aux.xml instead of using the VRT file for
managing category names.
I agree that avoiding the .aux.xml would be more convenient.
Best regards,

Thank you for useful comments, Antonio.
I agree with you that the ideal thing would be to improve the support of
GDAL for our satellite data formats of interest. It would be great if we
could combine efforts and get some momentum on this.
Several formats (e.g. TerraSAR-X, Envisat ASAR, MERIS

Hi,
Our group is looking at the possibility to use GDAL with Python bindings
for our work with satellite data. One limitation seems however to be
missing/incomplete drivers, as we have no capacity to implement new
drivers in C.
It seems however to me that the Python API allows to create GDAL
