A content based MAP retrieval system for land cover data

In this paper, we design a Content-based map retrieval (CBM-R) system for land cover/land use (LCLU). The main contributions of our work are listed below. First, our system could allow the user to select region of interest as reference scene with variable shape and size. Whereas in traditional CBIR/CBMR systems, the region of interest is usually with fixed size of which is equal to the size of the analyse window for extracting features. In addition, the user could acquire various retrieval results by specifying corresponding parameters. In the end, by using combination of the feature library, the user could acquire the retrieval result faster.
