| Abstract: | At present,DEM has a large development at both theory and practice.DEM has been applied in many fields such as surveying and mapping,geology and engineering.Therefore,it is necessary to enhance the precision of DEM and to check the quality of DEM.This paper introduced how to control the quality during producing DEM using VirtuoZont system and method of error detection,and introduced the how to check the quality of DEM. |
