So you have a large KML files, and you want to render portions of it in Google Maps, correct?
If the KML is too large you're going to have problems loading it into either Google Maps Javascript or flash api. As far as I am aware, there is no difference in coordinate systems between Google Earth and Google Maps, what I would recommend is using Google Earth and deleting all the polygons you don't want/need, and then you can use Google Earth to save the new file with only the selected polygons you are looking for. Hope this helps. Jonathan Scribblemaps.com On Jan 17, 1:39 pm, Alexis <[email protected]> wrote: > I acquired a KML file containing polygons of the Regions of the > Philippines.
