Below in conjunction with accompanying drawing, the present invention is further described.
Shown in Figure 1, be system software block diagram of the present invention.
In the drawings, the data of core and pattern management system process and display the signal by data acquisition system (DAS), graphic plotting system, graphic display system and four subsystem inputs of image editing system, finish every work of mapping content.Wherein, data acquisition system (DAS) is by being provided with dialog box, measuring dialog box and the computer dialog frame is gathered relevant data, the acting as of each dialog box:
(1) dialog box is set, in order to type, the communications parameter that the input data information instrument is set, for example baud rate, data bit and position of rest etc., and instrument height, Geographic Information System GIS interface, Global Positioning System (GPS) GPS interface, sampling interval etc. are set.
(2) measure dialog box: be used for the input of angle, distance and elevation data information.
(3) calculate dialog box: be used to carry out the various results' of measuring calculating.
By relevant interface connection for what data acquisition system (DAS) provided data message can be with communication
(1) total powerstation comprises that the guest gets, Suo Jia, opens up instrument of surveying and mapping system both at home and abroad such as Pu Kang, Nikon, come card;
