Embodiment Construction

[0036] The present invention will be further described below in conjunction with specific embodiments, but not limited thereto.

[0037] A digital city generation method, the typical steps are as follows.

[0038] Step A, obtaining geographical information data of a predetermined area, and establishing a three-dimensional basic database of the area:

[0039] Step A1, obtain a map of a predetermined area, and calculate the length data and coordinate data of each region and object in the predetermined area through a detection algorithm;

[0040] Step A2, obtaining the height information of the predetermined area, and calculating the height data of various regions and objects in the predetermined area through a detection algorithm;

[0041] Step A3, according to the length data, coordinate data and height data of each region and object in the predetermined area, establish a three-dimensional basic database of the area;

[0042] Step B, obtaining the type and shape data of each ...

Abstract

The invention relates to a digital city simulation system, belonging to the virtual technology, in particular to generation method and system in the city plan and construction design field. The system is a professional assisted decision system and a management platform oriented to the government departments, and is also a multimedia propaganda platform with internet and professional server colonygenerality showing the government plan construction fruits. The system is in gapless connection of fusion of planes, positive image mapping and three-dimensional map technology, the double-accuracy of positioning and logic can be implemented totally based on a GIS (Digital Geographic Information System) and a city coordinate system in accordance with the technical data of a total plan, blue linesand red lines and the like provided by the plan departments, and the system can be used as a decision tool.

Description

technical field [0001] The invention relates to a digital city simulation system belonging to virtual technology, in particular to a generation method and system in the fields of urban planning and architectural design. Background technique [0002] The 3D digital city is one of the basic symbols of the transition from the industrial age to the information age. It generally refers to the intelligent recognition of massive data that can be effectively acquired, classified and stored, and automatically processed in the category of urban "natural, social, and economic" systems, with high resolution and high intelligence, capable of both virtual reality and direct Participate in an integrated project of urban management and services. The 3D digital city demonstration involves surface landforms, river waters, urban core commercial streets, urban landmark buildings, main buildings, residential buildings, key enterprises and institutions, road network streets, landscaping, street ...
