Abstract

The invention discloses a method for quickly integrating and displaying a three-dimensional geographic information system, manufacturing a three-dimensional scene, establishing a three-dimensional building model and developing a three-dimensional geographic information system platform; a TerraBuilder in SKyLine is adopted to create a three-dimensional bottom surface model which is accurate in geographical registration and has a photograph live-action effect for a terrain visualization application system, the compilation is carried out, and data, images and DEM are added. The invention relatesto the technical field of three-dimensional geographic information systems and discloses a method for quickly integrating and displaying a three-dimensional geographic information system. The problemthat the existing GIS development mode has two modes is solved. According to the first method, professional three-dimensional or 2.5-dimensional software is used as a platform; the other one is to perform three-dimensional secondary development on a professional two-dimensional GIS software platform, but the former is more powerful than the latter in the aspect of three-dimensional model establishment, and the latter has more advantages than the former in the aspect of three-dimensional space analysis function, and how to combine the advantages of the former and the latter together to solve the problem of deficiency.

Description

technical field [0001] The invention relates to the technical field of three-dimensional geographic information systems, in particular to a method for rapid integration and display of three-dimensional geographic information systems. Background technique [0002] Geographical information systems are sometimes referred to as "geoscience information systems" or "resource and environmental information systems". It is a specific and very important spatial information system. It is a technical system that collects, stores, manages, calculates, analyzes, displays and describes the relevant geographical distribution data in the entire or part of the earth's surface (including the atmosphere) space with the support of computer hardware and software systems, and displays spatial information. more intuitive. Since people know how to understand and transform the world through spatial information, spatial information mainly exists in the form of graphics. However, displaying spatial ...
