Nine Tiles Model Construction and Cache of CGML in Mobile

Nine Tiles Model Construction and Cache of CGML in Mobile

Document management is a usual way to organize spatial data in mobile terminals. And the compressed CGML spatial data has been widely used in location based services. Referring to the thoughts of map set in cartography, nine closely connected and equal sized rectangles are used as the scope for requ...
