【Abstract】 The data management of various remote sensing platforms or sensors and the implementation of associating data of various scales are the key points in building the national standard spectral database for typical land surface objects which involves the processing of mass data, the correlation among images of different scales and the transfer of compressed data in network environment, etc. This story puts forward a solution based on spatial segmentation and areal image data link. Through incising data according to topographic maps and adopting standardized processing, standardized image data is formed from that of different scales, which provides a platform to the scale investigation and model implementation supported by the spectral database.更多还原
