This paper based on 4S(GPS, GPRS, GIS and RS technology in a integrated system) and designed a remote sense image calibration system by using a high precise GPS module which is integrated in the handheld client device. This article designed and realized a software architecture and a data storage and transfer model though the GPRS real-time network. The handheld devices based on 4S changed the poor...
