The invention relates to a 
system to provide local mobile geographic information service based on GPS and mobile terminal. The 
system comprises: a 
wireless communication network, a GPS position apparatus and mobile terminal, and an internet and 
path tracking server. The innovation of the invention is adding the following 
software functional modules in the mobile terminal: a 
wireless communication module, a GPS receiving module, an interface displaying module, an interest point inquiring module, a path planning module, a positioning module, a 
path tracking module, a GIS engine module, a 
database management module and a data layer made up of an interest point 
database, a geographic 
data file, a geographic data index file, a geographic data topological file and a initialization configuration file. The 
system achieves the advantages of simple, practical, smart in data layer design, convenient in inquiring, low in cost and easy to implement. For storing 
geographic space data and integrating many 
software functional modules in the mobile terminal, the system in the invention enable the user to enjoy localized real time 
geographic space position service conveniently at any moment with less dependence on the 
server.
