| Abstract: | Although Undo/Redo operation is a familiar operation in software, to GIS, there is a special requirement with doing the Undo/Redo operation. This paper deeply researches on the Undo/Redo operation of GIS software via the foundation of analysis its principle and mechanism. In addition, this paper designs an abstract class for GIS software＇s Undo/Redo operation. At last, the paper gives an applied example of this class. |
