Spectral classes generated from image classification are conventional output in land-use and land-cover (LU/LC) mapping with digital remotely sensed data. The spatial composition of these spectral classes within a certain spatial range, or window, can be useful information for image analysis. In this study, the concept of spatial composition of spectral classes (SCSC) was developed and examined. It was found that LU/LC types did exhibit different characteristics of SCSC. Ranges of SCSC were used for post-classification labeling to identify different LU/LC types. Results showed that a 7 by 7 window size was suitable for Hong Kong at Level-II classification. 18 refs.
