Abstract

The invention provides a method for generating an electronic map. The method includes a data collecting procedure, a data storage procedure and an electronic map displaying procedure, wherein the data collecting procedure includes a step of collecting vector data and additional data corresponding to the vector data; the data storage procedure includes the steps of storing the collected vector data and the collected additional data in a server database, enabling the vector data corresponding to different types of main body elements to be stored in a plurality of layers, and enabling the vector data of each type of main body elements to be stored in one layer; the electronic map displaying procedure includes the steps that an electronic map displaying end obtains the vector data and the additional data from a server, draws vector diagrams corresponding to each layer of vector data layer by layer according to the vector data in each layer, and adds the additional data related to main body element identification data (ID) in the layer of vector data, and consequently the electronic map is generated in a displaying device.

Description

technical field

[0001] The invention relates to a method for generating electronic maps, in particular to a method for generating relatively small-scale electronic maps such as airports, exhibition halls, parks, and shopping malls. Background technique

[0002] Electronic map (Electronic map) is a digital map, which is a map that is stored and consulted digitally using computer technology. The basic flow of the method for generating an electronic map mainly includes steps such as data collection, data storage, data analysis and display.

[0003] The current mainstream electronic map data comes from geographic information system (GIS, geographic information system). GIS includes a series of complex theories such as collection, processing, storage, analysis, display, and spatial analysis of geographic data.
