Software system for making three-dimensional city map

Abstract

The invention discloses a software system for making a three-dimensional city map. The system comprises a three-dimensional vector establishment module, a three-dimensional city map establishment information display module and a data updating module. The output end of the three-dimensional vector establishment module is connected with the input end of the three-dimensional data simplification module. The output end of the three-dimensional data simplification module is connected with the input end of the three-dimensional vector information conversion module and the input end of the three-dimensional information establishment analysis module, and the output end of the three-dimensional vector information conversion module is connected with the input end of the information import system. The invention discloses a software system for manufacturing a three-dimensional city map. The three-dimensional map can be automatically established through cooperation of the three-dimensional vector establishment module, the three-dimensional city information analysis module and the three-dimensional city map establishment information display module, the problem that the three-dimensional map is difficult to establish is solved, the three-dimensional maps can be established in batches, and workers can plan cities conveniently.

Description

technical field [0001] The invention relates to the technical field of three-dimensional electronic maps, in particular to a software system for making three-dimensional city maps. Background technique [0002] A three-dimensional electronic map, or 3D electronic map, is a three-dimensional, abstract description of one or more aspects of the real world or a part of it based on a three-dimensional electronic map database. The network 3D electronic map not only provides users with map retrieval functions such as map query and travel navigation through the intuitive representation of geographical real scene simulation, but also integrates a series of services such as life information, e-government, e-commerce, virtual community, and travel navigation. While bringing convenience to people, the three-dimensional electronic map of the network also brings threats to national security, social stability and people's privacy. As a form of graphic language for recording geographic inf...
