Abstract & Keywords
Abstract: As one type of plane grid data, remote sensing image can reflect the earth surface with map projections. Normal standard remote sensing data are divided into scenes based on certain rules. Satellite data vary by framing and coding rules. The scenes of remote sensing data do not correspond to the geographical coordinates of the earth. The Ready-to-Use (RTU) geogrid product of remote sensing data is introduced in this paper in order to make the long-time sequence image easier to query, analyze and manage. 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 subdivision and encoding methods of remote sensing image according to longitude-latitude grid and Cartesian coordinate grid, and RTU geogrid products, which are applicable to subdivision and encoding of remote sensing images with different resolutions based on different projected geographic grids , and the production of RTU geogrid products. RTU geogrid products are flexible, and geographical coordinates are consistent with geocoding. Data cubes can be built according to spatial and temporal dimensions to create products that provide continuous information flow in space and time, which is easier for users to carry out spatial analysis and apply . This specification provides spatial reference based on geographic grid for remote sensing image sharing and remote sensing information integration, which can be used for analysis and application of remote sensing images with long-time sequence and different spatial resolution.
