Abstract: This paper decribes a experiment study of river flood control information system (FCIS) for remote sensing system of flood control. Through a methodological study of input, output, and processing of graph and remotely sensed image, the microcomputer-based system is established by using a compiler method mixed DBASE-Ⅲ with FORTRAN,BASIC and C.The functions of FCIS include data storage, updating,retrivial,display,mapping; graph and imagc input/output, save/load, edit and processing.
