Remote sensing image information issue based on C-S and B-S

Remote sensing image characteristics, bandwidth limitation and security are the most important consideration to remote sensing image issue. For more effectively issue image information, a strategy is adopted to divide Web users into C/S (client/server) mode user and B/S (browser/server) mode user. The complex data operations and system functions, coordinate scope query of area of interest by WebGIS or metadata can be used by C/S mode user; But the B/S mode user which is used by common users can only obtain retrieval service, such as image samples retrieval, image metadata retrieval and other related retrieval or acquiring of relatively little quantity of data. Of course, the framework that DEM, vector, raster and other related data are integrated also are discussed. Then, spatial data sharing and exchanging based on XML are proposed. Finally, a system of B/S mode is designed and implemented.
