ArcGIS支持下的海岸带DEM构建与精度评估分析

以福建九龙江口海岸带DEM数据构建为实例,介绍了基于ArcGIS软件综合陆域、海域以及海陆交界处干出滩数据,构建海岸带DEM并进行精度评估的方法。精度评估结果显示所构建的数字高程模型是满足国家DEM构建相关标准精度要求,从而为GIS在海岸带资源信息化综合管理中应用提供了技术支撑。

Coastal DEM Construction and Accuracy Assessment Based on ArcGIS

Taking the building of Fujian Jiulong River coastal DEM data for example, the paper introduced a method of Coastal DEM construction and accuracy assessment based on ArcGIS through integrated the land, marine and foreshore flat areas data. The accuracy assessment result shows that the Jiulong River area Coastal DEM of Fujian meets national standards of DEM production. So, this paper provides a technical support for the application of GIS in the coastal resource integrated management based on information.
