Embodiment Construction
[0059] Such as figure 1 As shown, the quick drawing situation plotting system of the present invention is divided into 4 layers, which are respectively a display and control terminal, an operating tool set, a data processing layer and a system support layer.
[0060] The display and control terminal is mainly used to display the GIS system and plotting content on the screen and complete the touch operation to draw graphics. The display and control terminal can be a touch operation screen or a mobile touch device.
[0061] The operation tool set mainly completes the key steps of the entire drawing process, including the start and end function buttons, the erase function button and the drawing edge style setting button.
[0062] The data processing layer lists several key plotting processing algorithms and technologies, including mouse event capture algorithms, screen coordinates and latitude and longitude conversion algorithms, GIS plotting algorithms, plot erasure processing algorit...
