Google recently released new vector cartography for their mobile maps. I'm curious if anyone here has any insight into the wire format they use for transmission? I've experimented with a few formats over the years, including bencode, bson, variants of WKT and WKB, and gzipped, limited-precision geojson which I've found to be the best trade-off in comprehensibility and file size. I'd love to know what Google decided on, but I don't have an Android device to test with.
