| Abstract: | As a efficient and practical method, computer-aided mappign is used in calculating area of landuse and flexible to users. This method raises efficieny to 230% and saves the cost more than a half. The study proved that the method is practical and efficient. This paper introduces mainly the following points.1. The working environment of hardware and software in computer-aided mapping.2. The technique graph editing and encoding.3. The methods to digitize graph and to build praph database.4. Inputing,replacing and modifying of the attribute data.5. Inspecting error messages,set up relaion among points,areas and polygons.6. Calculating area and mapping. |
