| 摘 要： | 选择地形地貌比较复杂、地质构造比较发育的湖南省为研究对象,采用SRTM DEM为DEM数据源,经过数据处理、投影转换和MapGIS、ArcGIS数据格式的相互转换,以及湖南省构造地质图在DEM上的叠加,实现了湖南DEM三维构造地质图的制作。将二维构造地质图转向三维空间,使图件在确保专业性的基础上具备立体感和层次感,并表达出实际的地形地貌特点,从而缩短一般工程技术人员构造地质图的读图时间并提高读图质量,具有较大的应用价值。 |

| Abstract: | Choosing Hunan Province as the research object for its complex topography and well-developed geological structure and using SRTM DEM as the DEM data source, the authors, through data processing, projection conversion, MapGIS and ArcGIS data format conversion, and the superposition of the geological structure map of Hunan on the DEM, compiled the DEM 3D geological structure map of Hunan, realized the conversion of 2D geological structure map into 3D space. The resultant map not only keeps the professional nature but also shows three-dimensional effect and the sense of hierarchy through expressing the actual landform condition. In addition, it can reduce the time for reading the map and ensure the quality of interpreting the images. The results obtained by the authors have remarkable application value. |
