The design and implementation of massive map tile storage technology oriented to the mobile terminal

Abstract

According to the statistics of MIIT, at the end of January 2014, China mobile users had reached 1.235 billion. Maps as mobile internet key entrance, whether ordinary users or enterprise customers have unprecedented requirements to user experience of the map, traditional mobile map using online tiles load slowly, and can not meet the needs of the current application. The ability to quickly load map tiles from GIS Servers has become an urgent problem to be solved in mobile mapping applications. This paper analyzes the map tiles implementation principle and the present situation of the mobile terminal maps, and then based on the study, a mobile terminal oriented massive map tiles storage technology is proposed which is based on embedded database, and finally, an index algorithm is employed to the map display. The technology after a full practice verification can effectively improve the loading speed of map tiles, and it can be a good solution for map tiles fast reading and writing. At the same time, the storage technology has characteristics of portability strong and synchronization convenient.
