Electronic map drawing method and device

Abstract

The invention provides an electronic map drawing method and device. The electronic map drawing method includes: acquiring an original image and administrative division information of a target drawingarea; based on the original image, collecting elevation information of terrain factors in the target drawing area to acquire corresponding elevation information; based on the original image, performing vectorization collection on classified information of the surface factors in the target drawing area to acquire corresponding vectorization data; according to the elevation information correspondingto the terrain factors and the vectorization data corresponding to the surface factors, drawing a map frame of the target drawing area and performing information association on the map frame on the basis of the administrative division information to acquire an initialized map; performing data check on the initialized map and subjecting the initialized map to map modification according to a checkresult to acquire a corresponding electronic map. The method has the advantages of small resource consumption, low in drawing difficulty and high in drawing efficiency, and the electronic maps with high accuracy can be provided for users.

Description

technical field [0001] The present invention relates to the technical field of electronic map surveying and mapping, in particular to an electronic map drawing method and device. Background technique [0002] With the continuous development of science and technology and the continuous improvement of people's living standards, electronic maps have the advantages of accurate data, short update cycles, and the ability to intuitively display land features, road information, housing construction and other information. The position occupied in daily life is also becoming more and more important. Therefore, how to improve the drawing efficiency and drawing accuracy of the electronic map is an extremely important issue for the electronic map surveying and mapping technology used for surveying and drawing the electronic map. [0003] For now, the mainstream of the industry usually uses manual field surveying and mapping to measure the relevant data of each building in the target map...
