摘　　要：以东北林业大学帽儿山试验林场航片和地形图为资料,采用数字微分纠正理论与技术制作1∶10 000数字立体正射影像,其精度满足林业用图需要。制图过程中,对地形图配准结果和DEM结果进行了精度检验,并提出了一种对DEM精度进行检验的方法———重合度法。最后就立体正射影像图的应用作了一些探讨。A digital three-dimensional orthophotomap with a scale of 1∶100 00 was made by adopting the theory and method of digital differential rectificat ion based on the aerial photos and relief maps of Maoershan Experimental Forest Farm of Northeast Forestry University, and its precision could be accepted by fo restry using map. During the process, the precision of results of geographic rec tification and DEM for relief map was verified, and a method of superposition de gree was put forward in order to verify the DEM precision. In the end, the appli cation of digital three-dimensional orthophotomap was discussed.
