[gdal-dev] KMZ Support in OGR?

Thanks - that would seem like a good way to go in the future, though I 
don't have time to work on it myself...

As I understand it, the BSD license allows free distribution and use of 
source code and binaries, with or without modifications. The only 
caveats are that (a) you mustn't remove the copyright notices from the 
source code, (b) you must acknowledge the copyright somewhere in the 
documentation of your library / app that uses the code, and (c) you 
mustn't assert that the author of the original code endorses the derived 
library / application. Is this compatible with the GDAL license? Maybe 
the google people would be flexible if it isn't?

Wouldn't this make a perfect Google Summer of Code project? Can someone 
add it to the GDAL SoC ideas page?

Cheers,

Sy
