LIU Xu-long, HE Chun-yang, PAN Yao-zhong, et al. Accuracy Assessment of Thematic Classification Based on Point and Cluster Sample[J]. Journal of Remote Sensing, 2006, (3): 366-372. DOI: 10.11834/jrs.20060356.
In order to assure the application of thematic classification
it is very important and necessary to make a rigorous accuracy assessment.In this paper
we use sampling-methods of point and cluster sample to assess the accuracy of the same region’s land-use/land-cover thematic maps
which are derived from different resolution remote sensing data.Here
Sampling designs are consisted of simple random
systematic and stratified sampling.The results are as following.Firstly
the sampling design has great impact on the accuracy of remote sensing classification.There exists great randomicity on the result of points and cluster sample verification on the different Sampling design.On the same sampling design
the stability of point sample verification is higher than that of Cluster sample verification.Secondly
the average accuracy of different sampling designs of multi-point and multi-cluster sample verification can reflect the accuracy characteristic.During the course of point sample verification
stratified sampling’s error is lower than others’.During the course of cluster sample verification
systematic sampling and stratified sampling’s accuracy are prior to simple random sampling’s.
