Abstract

Applicable to the field of electronic maps, the invention provides display method of an electronic map. The method includes: acquiring current display control information, which comprises a current map display scale, a map display view angle as well as display position information; generating and displaying an electronic map according to the current display control information, with the electronic map composed of road information and three-dimensional block information. Specifically, the road information contains abstract roads, which are generated based on center lines formed by connecting each road recording point that can reflect road elevation information; and the three-dimensional block information includes three-dimensional urban buildings. Correspondingly, the embodiment of the invention also provides an electronic map display terminal. Through the embodiment of the invention, electronic map display can be realized, so that users can more visually understand urban geographical environment information.

Description

technical field [0001] The invention belongs to the field of geographical information, in particular to an electronic map display method and a terminal. Background technique [0002] In recent years, with the continuous popularization and development of the Internet and navigation applications, electronic maps have risen rapidly due to the use of the Internet and navigation hardware as the carrier. Maps have gone from paper to the Internet, personal computers, and vehicle and handheld devices. People can easily search for places of interest, driving routes and bus routes in the electronic map, and provide reference suggestions for travel arrangements. As we all know, we live in a real three-dimensional real world, and the traditional two-dimensional map only simplifies the projection of all kinds of geographical objects in three-dimensional space to the two-dimensional plane, resulting in the third-dimensional direction (that is, the vertical direction). The lack of geometr...
