摘要

By GIS, the various natural factors and social and economic factors of the plan area can be expressed different coverages that are in the same geodetic coordinate system. By qualitative and quantitative overlaying analysis of these relational coverages, many middle results and positive results can be yielded. The jobs of Area measuring and statistic are easy. The work efficiency and the reliability of programming data will improve greatly.
