| Abstract: | The author has already made elementary experimental research for data collection and edition pmeess in GIS. During the experiment, the author adopts dinitalizer s conection program on arc segtnent in real time edition to conect original data. On the basis of the otiginal arc segtnent data files. the arc segment index files polygon index files and sequential polygon index files employing topological relation can be established. thus, it greatly increases data search efficiency and enhances display effect. |
