Jim,
GML driver doesn't support reporting of the geometry type for the layer.
However, you will get the right geometry when you ask for the geometry
itself. Try "ogrinfo -al test.gml" and check the reported geometries.

First you have to locate the corner pixels corresponding to the lat/longs
you indicated. Go through (http://www.gdal.org/ogr/osr_tutorial.html) to do
that. Use "WGS84" system for lat/longs.
Use GDALRasterIO() (http://www.gdal.org/gdal_tutorial.html) to retrieve the

I believe -a_nodata in gdal_translate sets the no data value as in
GDALRasterBand::SetNoDataValue(). -dstnodata in gdalwarp initializes the

Dear GDAL,
What is the difference between gdal_translate's "assign nodata" and
gdalwarp's "destination nodata"?
thanks!

Try with GDAL 1.7.1 instead... this is the I could compile with

If we assume that each S57 object corresponds to a real world entity -
in my opinion the best encoding would be a separate line object. I.e.
the main road is a point to point entity (as LineString supports) and
the spur from the east (such as the one from Ljubicevac) is a separate
line. That would
