DEM data coordinate transformation and quality inspection method of transformation results
In response to the demand for three-dimensional(3D)coordinate transformation and quality inspection of transformation results based on digital elevation model(DEM)data,this paper studied the technical methods for implementing plane coordinate transformation and elevation coordinate transformation of DEM data based on the ArcGIS development engine platform.At the same time,according to the characteristics of DEM data,reasonable quality inspection contents and indicators for DEM data transformation results were studied and formulated,solving the practical production application problems of quality inspection standards for DEM data transformation results.The research results of this paper can ensure the application of DEM data in Beijing under a unified benchmark,promoting planning,construction,and management related to geographic information surveying and mapping.
