System for providing local mobile geographic information service based on GPS and mobile terminal

Abstract

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.

Description

technical field [0001] The present invention relates to a communication system for providing geographic information services, to be more precise, relates to a system for providing local mobile geographic location information services (LBS, Location Based Service) using GPS and mobile terminals. Using this system, you can choose to consult, Displaying a local map and performing zoom processing on the map, as well as realizing functions such as positioning, querying points of interest, navigation and path tracking, belong to the technical fields of telecommunication value-added services and computer applications. Background technique [0002] With the advent of the era of knowledge economy, information has become the source of wealth for human society. At present, more than 80% of the information in people's production and life is related to geographic spatial location. The rapid development and wide application of information science and technology have led to the demand of ...
