Abstract & Keywords
Abstract: Remote sensing image is a kind of plane grid data, which reflects the surface of the earth in a certain map projection way. Normal standard remote sensing data are divided into scenes according to certain rules. Different satellite data have different framing and coding rules. The scene of remote sensing data does not correspond to the geographical coordinates of the earth. The Ready To Use (RTU) geogrid product of remote sensing data is proposed in this paper in order to make the long-time sequence image easier to query, analyze and manage. That is, the global image is divided into data grids with resolution, corner coordinates, grid size, product type and other attributes according to the defined grid system. This specification specifies the division and encoding methods of remote sensing image according to longitude and latitude grid and Cartesian coordinate grid, and RTU geogrid product, which are applicable to different resolution remote sensing images, according to the different projection geographically dissecting and encoding, and the production of RTU geogrid products. RTU geogrid products are flexible in use, and the geographical coordinates is consistent with geocoding. Data cubes can be built according to spatial and timely dimensions to form continuous products in space and time, which is convenient for users to directly carry out spatial analysis and application. This specification provides spatial reference based on geographic grid for remote sensing image sharing and remote sensing information integration, which can be used for comprehensive analysis and application of remote sensing images with long time sequence and different spatial resolution.
