In order to verify the precision of the land surface water areas calculated during this project,we used a two-stage sampling model test for our spatial data.In the first stage,the test model was“frame sampling”,as each sampled unit was a frame,while in the second stage,the the test model was‘element sampling’,as each sampled unit was an element.Thus,80frames were sampled globally in order to evaluate precision(Figure 8,Figure 9),6,438sample points were selected at random.The results of this analysis show that the precision of sample mapping was 82.77%,while user precision was 92.09%.
