| Abstract: | For the need of mapmaking,the passage discusses some of the mathematical basis of oblique coordinate system,including the concept of constitution,calculating formular and the transformation with coordinate system in right angle etc.From the angle of applying of mapping the authors deeply analyse the distortion of the oblique coordinate net,which makes the basis for selecting the angle of the axes,and properly designing of the oblique coordinate system when plots the graph.All these make the graphs visual easily reading and strongly contrasting. |

| Keywords: | the oblique coordinate system mathematical basis analysis of distortion selection of angle of the axes |
