| Abstract: | The precision of DEM was analyzed in full detail.A great deal of experiment based on SURFER was performed.The pertinent limition of SURFER was improved.Maps with larger error were interpoated over again,and the precision was improved.The system of DEM precision detection and analysis was developed,which included several functions such as workspace creation,vector browsing,attribute data modification,data format transformation,map border cuting and meeting,DEM precision detection,precision analysis and preci... |
