A two-level sampling model was used to ensure the objectivity of the accuracy evaluation on the artificial land surface classification.The first level was termed“frame sampling”,which takes“frame”as the sampling unit.The second level was called“element sampling”,at which we took“the spatial classification element in the frame”as the sampling unit to calculate the quantity of samples of each level that needs to be taken,then the samples were arranged by combining spatial variability analysis.80frames were taken at a global level,4,269 samples were used to conduct a accuracy evaluation on the artificial surf-aces product in 2010.The result showed that the dataset producer’s accuracy was 64.56%,and the users’accuracy was 86.97%.Figure 10 and Figure 11 were two examples.
