数字高程模型误差分析及精度评价述评

Comprehensive Review on Error Analysis and Accuracy Appraisal of DEM

从数字高程模型的误差入手,详细阐述了数字高程模型(DE M)的数据采集误差和内插计算及建模误差,并在此基础上进一步比较分析了数字高程模型的精度评价方法。

Starting from errors of DEM, errors in data collection, interpolation calculation and model-setting were compounded. Based on the conclusion drawn above, accuracy appraisal of DEM was analyzed.
