The foundation of a grassland 3D-digital model for Xilin Gol

Abstract

Abstract: To promote the further development of information-based management of grasslands, this work established a grassland three-dimensional digital model based on modern information technology, including 3D-GIS technology, remote sensing technology, simulation technology and other related technologies. The foundation of the 3D-digital model is based upon the Xilin Gol grassland as a demonstration area. The establishment of this digital model is based first on screen grassland information data (maps data and attribute data) according to the principles of grassland ecology; second, an overlay of the layer data filtered to establish the association with attribute data. Finally, the grassland information data was embedded in the three-dimensional virtual space model, to realize queries and analysis of grassland information. The research showed that the grassland three-dimensional digital model developed using the C/C++ language to call OpenGL graphics library works fast and steadily with fast rendering speed, and can provide real-time and dynamic queries of grassland information, and supply technical support for further studies on three-dimensional virtual grassland.
