I've created an online map containing drive-time layers across approximately 20 locations in Eastern Canada. I'm finding that when I go to download this file as a KML, it's size (approx. 40MB) is far too big for me to handle for my purposes. I'm looking for a way to compress the file significantly - one thing I'd like to find out is if it's possible to reduce the accuracy of the drive-time map (i.e. round off the layer boundaries to reduce the file data required), but all methods of compression/file size reduction are welcome.
Your input is appreciated. Right now this is the single obstacle preventing me from using the output file.
Thank you in advance,
