摘要
文中提出一种基于等高线、高程点、特征地物信息数据的方法进行DEM数据生产,生成的DEM数据利用实测地面数据对其进行质量检测与精度评价。结果表明,生产的DEM数据可以将研究区内的河流、堤坝、山地、居民地等地貌信息较好的表现出来,符合数字测绘成果规范要求。
The paper proposes a method of DEM data production based on the information data of the contour line, elevation point and the features ground object, the quality inspection and accuracy evaluation is carried out for the production DEM data by using the measured ground data. The results show that the DEM data could better display the geomorphologic information of the study area, including river, dams, mountains, residents, and so on, which could meet the digital survey code demand
