Problems solved by technology

At present, there are many 3D graphics display systems in the industry, but most of them are based on the C / S structure. Users need to download and install the client, which has the limitations of traditional desktop GIS, and there are relatively few systems based on browser access, such as ActiveX. Although the system development of WebGIS is based on browser access, the 3D GIS system based on plug-ins, the installation of plug-ins, and compatibility issues all hinder user access and reduce user experience.

Abstract

The invention relates to a WebGIS three-dimensional model system based on WebGL. The WebGIS three-dimensional model system comprises a webpage Web browser, a webpage Web server, a WebGIS server and abottom layer data library, the webpage Web browser is used for providing an interactive interface, directly displays three-dimensional image information by calling a user-defined vector layer, sends arequest and receives a response request; the webpage Web server is used for the request sent by the webpage Web browser end; the WebGIS server is used for providing management and service work of spatial data; the bottom layer data library includes a three-dimensional model library and is used for storing information data and the vector layer. Through the user-defined vector layer, the WebGIS three-dimensional model system is directly added into 3D GIS to display 3D terrains, feature details and internal information to avoid downloading and installing of a client end and the problem of compatibility, user visiting is more conveniently and rapidly, and user experience is promoted.

Description

technical field [0001] The invention relates to the application field of WebGIS, in particular to a WebGIS three-dimensional model system based on WebGL. Background technique [0002] With the strong support of information technology, advanced hardware and sophisticated software, two-dimensional GIS has developed into an important part of the world's information system. It has applications in research, health management, environmental science, transportation and geospatial industries, urban mapping, public health, sustainable development, climatology and archaeology. On this basis, 3D GIS has also achieved rapid development in technology realization, and 3D GIS has also shown its hidden infinite vitality to people in the process of continuous technological progress. Through the display of the three-dimensional earth, people can not only understand the parallel and vertical relationships between spatial objects, but also provide spatial data display and spatial data analysis...
