摘要
借助GIS强大的三维建模及可视化分析功能,以湖北省崇阳地区1:50 000区域地质成果为例,基于地理矢量数据、地质矢量数据和遥感影像数据,利用地形数据构建数字高程模型(DEM),将DEM与遥感图像叠合生成三维影像图,建立集地形、地质、遥感等数据为一体的三维可视化模型,解决传统二维地质图件用于表示三维地质不直观等问题,提高地质空间分析的能力。
GIS has the function of powerful three-dimensional modelling and visualization analysis.By using areal geology achievement of Chongyang,Huhei Province for example,DEM was created by using terrain data and the three-dimensional terrain map was created by mergeing image with Digital Elevation Model(DEM) based on geographical vector data,geological vector data and image data.The three-dimensional visualization model was created by integrating terrain data,geological data and image to solve the problem that three-dimensional geology couldnot be described intuitionally by two-dimensional geological map and advanced spatial analysis capability.
