Abstract:
Aiming at the problems of safety shot chart mapping， the automatic cartographic algorithm is proposed, which is based on spatial reference, spatial analysis, cartographic expression. According to the location of the station，the accurate space reference coordinate system is adopted. Distance circles and azimuth rays are generated by analysis tools, and the generative process of the safety shot sector zone is derived from the set theory. On account of derivation results，the tools such as SymDiff_analysis, FeatureToPolygon_management, and SelectLayerByLocation_management were integrated to the completed spatial analysis process.The application shows that users just need input the related data，and the drawing process is without humancomputer interaction, which can guarantee the accuracy of the drawing elements and put an end to the possibility of leakage.
