Abstract

The invention provides a map data acquisition method, a computer readable storage medium and a terminal device. The map data acquisition method comprises the following steps of acquiring a boundary ofa target area; according to the boundary of the target area, determining a crawling area of the web crawler, wherein the crawling area is a closed area composed of a plurality of line segments, and the crawling area comprises the target area; aiming at a straight line corresponding to any line segment in the plurality of line segments, determining a linear function of the straight line in a map coordinate system corresponding to the third-party map; establishing a boundary constraint condition for crawling map data of a third-party map by the web crawler according to the linear function corresponding to the plurality of line segments; calling an interface of the third-party map, and crawling map data of the third-party map through the web crawler according to the boundary constraint condition. The latest map data is crawled through the web crawler, so that the real-time performance of obtaining the map data is improved, the situation that the crawler crawls a large amount of invalid data is avoided by determining the boundary of the crawling area of the web crawler, and the calculation amount of the server is reduced.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a map data acquisition method, a computer-readable storage medium and a terminal device. Background technique [0002] With the rapid development of computer network technology and geographic information technology, geographic information data, as an important basic information data resource, has been widely used not only in urban planning, traffic navigation, disaster monitoring, national defense and military, etc. Moreover, it is more and more closely related to people's daily life. For example, from mobile phone maps and car navigation maps used in people's daily travel, to high-speed railways, airports, urban planning and construction in infrastructure construction, etc. Do not open support for geographic information. [0003] In many scenarios, it is necessary to obtain map data with high real-time performance. However, in the existing technology, geographic i...
