Nov 2, 2014 · You can try a quadkey. Translate the coordinate to a binary and interleave it. Treat it aa base-4 number. Then use gzip or a statistical compression.

This paper addresses a combined method of simplification and lossless compression to reduce the data quantity while preserving the map quality and to cope with ...

Mar 18, 2014 · The Google Map developer libraries make use of an encoded polyline format that churns out an ASCII string representing the points making up the polyline.

This scheme perfectly depicts the global characteristics of each polyline, and has complementary robustness for simplification, compression attacks and geometry ...

The goal of vector map compression is a compact repre- sentation of map data, with possibly some limited sacrifice of spatial accuracy. Lossy compression ...
