Beschreibung
Zusammenfassung:	The invention relates to the technical field of surveying and mapping, in particular to a geographic information surveying and mapping system which comprises a fixing seat, a protection mechanism is arranged on the upper end face of the fixing seat, a surveying and mapping instrument is movably connected in the protection mechanism, and three supporting mechanisms are annularly and fixedly hinged to the edge of the lower end face of the fixing seat at equal intervals. A transmission mechanism is arranged in the center of the lower end face of the fixing base, a fixing mechanism is arranged at the lower end of the transmission mechanism, the transmission mechanism drives the fixing mechanism to operate, the whole device is fixedly connected with the ground in cooperation with a supporting mechanism, the measurement stability of the surveying instrument is improved, and the measurement numerical value accuracy is improved. By designing the supporting mechanism and the fixing mechanism, the supporting mechanism
