A merge of two shapefiles 'file1.shp' and 'file2.shp' into a new file
'file_merged.shp' is performed like this (See
http://www.gdal.org/ogr/drv_shapefile.html):
% ogr2ogr file_merged.shp file1.shp
% ogr2ogr -update -append file_merged.shp file2.shp -nln file_merged
Then convert to GPX:
% ogr2ogr

Or are there some already pre-calculated masks/bounding boxes or
polygons for the DRGs and BSBs popular sheets

Ok it work thanks.
But i have cheked the three drivers (PDS, Isisi2 and Isis3) and for
each drivers there are several lacks :
(filename, nnn ) is not implemented.
i think i will try to implement this.
I will open a new message thread in this list for discuss of it.

Hello,
I don't know the answer to your question, but since GPX files are text
files, it is very easy to merge two GPX files wi

Thanks for your response. I will look your changeset and try for my

Hello!
I wonder if there is a script for image analyze and automatic clipping
for the freely available USGS DRGs and NOAA BSBs map sheets...
I guess it is quite often requested functionality and I am sure there
are some implementations for that already available, maybe even
open-source.
