[FWTools] Does gdal_translate support writing kml files from geotifs?

Hi Simon,

Getting the regionator to work with the FWTools implementation of GDAL
can be problematic.  Some of the Python code it uses has Python 2.4
dependencies, which necessitate a great deal of hacking in both the
regionator and FWTools to overcome.  The easiest way I have found to use
the regionator is on a Debian Linux system, with the python-gdal package
installed.  I have had a great deal of success using it in this fashion,
and it should not conflict with your previous FWTools installation.

It would be helpful to have at least a general sense of what you are
trying to do.  The superoverlay.py tool in the regionator is very useful
for generating large, region-based KML "superoverlays" that can be
loaded in Google Earth.  This allows you to display an orthophoto
mosaic, or large DRG, which would otherwise exceed the client's maximum
overlay size.  

I'd be happy to continue this conversation with you off-line, if you
feel that the topic is inappropriate for this list.
