Abstract

The invention relates to the field of intelligent terminal electronic maps, and in particular provides an intelligent terminal call system. The intelligent terminal call system comprises a network server and an intelligent terminal, wherein the network server comprises a map acquisition module for acquiring an electronic map picture, a picture dividing module for dividing the electronic map picture into map blocks, a vehicle information acquisition module for acquiring vehicle information, and a downloading module for downloading the map blocks and the vehicle information to the intelligent terminal; and the intelligent terminal comprises a computing module for computing a map area, an uploading module for uploading coordinates of the map area to the network server, and a receiving module for receiving the map blocks and the vehicle information downloaded from the network server. Accordingly, the invention also provides a method for downloading and buffering the electronic map. The system and the method can increase the downloading speed of the electronic map and the displaying, updating and operating speed on the intelligent terminal.

Description

technical field [0001] The invention relates to the field of call systems, in particular to an intelligent terminal call system and an electronic map downloading and buffering method thereof. Background technique [0002] More than 80% of the information in people's production and life is related to geographic spatial location. Geographic Information System (GIS for short), as an important tool, technology and discipline for acquiring, processing, managing and analyzing geospatial data, has received extensive attention and rapid development in recent years. [0003] The geographic information system based on Internet technology is called Web-GIS. In Web-GIS, GIS is extended through the functions of the World Wide Web (i.e. Web), and has truly become a tool used by the public—from any node of the World Wide Web, Internet users can browse the spatial data in the Web-GIS site and make thematic maps. , Carry out various spatial retrieval and spatial analysis, etc. One of the ...
