Compilation method and system for electronic map

Abstract

The invention discloses a compilation method and a system for an electronic map, wherein the defect that an electronic map cannot meet the inquiry requirement of the land utilization information in the prior art can be overcome. The method comprises the steps of collecting the relevant data of the land utilization information, wherein the relevant data of the land utilization information are composed of graphic data and statistical data; pre-processing the graphic data; subjecting the statistical data and the preprocessed graphic data to the layering and partitioned storage treatment; determining the multi-stage catastrophe-scale of the electronic map, and determining data content and a to-be-displayed level of detail at different measuring scales and under different data layering and partitioned structures; according to a land category classification system and the multi-stage catastrophe-scale, subjecting the preprocessed graphic data to the cartographic generalization, semantic translation and geographic information visualization treatment so as to obtain the multi-scale data of the electronic map of land utilization; subjecting the statistical data to data spatialized treatment based on a land utilization status vector diagram so as to form a thematic analysis diagram layer matched with a land utilization diagram; and generating the electronic map.

Description

technical field [0001] The invention relates to the technical field of geographic information mapping, in particular to a method and system for compiling an electronic map. Background technique [0002] In recent years, with the development of the Internet and communication technology, electronic maps play an increasingly important role in people's lives. Compared with paper maps, electronic maps, especially online electronic maps, have the advantages of strong up-to-dateness, rich information, intuitive display and easy query. Existing electronic maps such as Yahoo Maps, Google Maps, Baidu Maps, etc. integrate massive data such as geographic basic information, image data, traffic information, and service facilities, which greatly facilitates people's work, life, transportation, and entertainment, and is therefore widely used . [0003] However, there is still a lack of electronic maps related to land use that are shared with the public under the WEB environment. The exist...
