三维GIS数据模型之初步探讨 |
|
With the rapid development of science and technology, the application of GIS technology are increasingly being used in all walks of life, while the three-dimensional GIS data technology has accelerated the emergence of GIS-socialization, mass and the enterprise, enabling GIS is now making a stable, strong and vigorous steps towards maturity. This paper describes the basic concepts, the latest research and data structure of the three-dimensional GIS data model, and three-dimensional spatial databases and other related functions of an overview of the content.

地形三维可视化基本研究 |
|
The Geographic Information Visualization plays an important role in the study of geological information and geographic information, the two-dimensional plane in GIS makes the spatial features can be converted to raster images and vector maps, and then makes the relevant analysis has a further simplification in processing, in the meantime, the realization of the three-dimensional topography simulation has maked the geographic research even more fast, convenient, accurate and comprehensive. This paper describes the basic steps in the achieving process of the three-dimensional terrain visualization and a number of issues that need attention during the process of the realization.
