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

Hi Roger,

We have lots (1000's) of ASTER satellite images we want to overlay on 
Google Earth (there is a link to the ASTER satellite instrument with my 
name info below, ASTER images have 15 m pixels and are 60km x 60 km). We 
process the ASTER images ourselves and generate geotifs. We use GDAL to 
generate geo jpgs and it would be great if we could easily generate kml 
files to overlay on Google Earth and even better if this was part of 

I can install python 2.4,  I was using the 2.35 version of Enthon. I am 
not sure how things work with FWtools if I have python 2.35 (or 4) 
installed and FWtools with its own python 2.3 installed. In order to the 
stuff running I had to do the setup under FWtools so it sounds like I 
cannot mix and match with superoverlay running under 2.4 and fwtools 
(and gdal) under 2.35? Our group are mainly Windows rather than Linux so 
we are looking for a Windows solution.

Perhaps if Frank could let us know if there are plans for FWtools with 
Python 2.4 that would help? If there is a 2.4 version coming out it may 
be best to wait! Depending on what Frank says we can follow-up off the list.

Best wishes,


p.s. The ASTER images are spectacular! I can provide you with some hand 
generated example KML files if that helps.
