Seasat remote sensing observation data matching method and system

The invention relates to the technical field of remote sensing surveying and mapping, in particular to a seasat remote sensing observation data matching method and a seasat remote sensing observation data matching system. The method comprises the steps of setting a time match threshold value, a space match threshold value and a match time length in advance, and dividing the sphere face of the earth into uniform virtual reseaus according to longitude and latitude; inputting time, searching the remote sensing observation data in the match time length by taking the time as the index; and computing the reseaus corresponding to the remote sensing observation data, traversing each reseau according to the row sequence of the reseaus, and computing time difference of the remote sensing observation data of a first satellite and a second satellite, corresponding to the same reseau, judging whether the time difference is smaller than or equal to the time match threshold value or not, and finishing the match according to the judging result. The seasat remote sensing observation data match system comprises a networking module, an index module and a network match module. The seasat remote sensing observation data match method and the seasat remote sensing observation data matching system can greatly reduce the data processing amount and are higher in operation efficiency.
