密云县密云水库上游微机水土保持地理信息系统研究

The Research on Microcomputer Water and Soil ConservationGeographic Information System in Upper Reaches of Miyun Reservoir

介绍微机水土保持地理信息系统，着重讨论了图形数据的检查、整饰和索引，以及多图幅数据的管理，提出排序后人工引导的方法解决了图幅的接边问题。最后探讨了水土保持地理信息系统的制图问题。

To introduce microcomputer Water and Soil Conservation Geographic InformationSystem (WSCGIS),specially the check,modification and index of grapltic data,and manage-ment of multi一sheets of map data were discussed.Then a methed that is manually navigatingafter soring has been proposed to solve merge of adjacent sheets of maps.Finally,the mappingof soil erosion has been illustrated.
