摘要
针对岷江上游山区地理信息离散度高、可变参数多等现状,本文应用GIS技术,基于Geodatabase数据模型,建立了岷江上游山区地理信息数据库;在此基础上,以1∶1000 000和WGS_1984_UTM_Zone_48N坐标作为基准,利用GIS软件数据符号化功能,创建多用途专题图。岷江上游山区地理信息的数字化和集成化对协调岷江上游山区人地关系具有理论指导意义和实用价值,同时数据库支撑下的GIS制图,能够使地图制作便捷、美观,并实现区域专题图的标准化和规范化。
There are problems of high dispersion and variable parameters in the geographic information of mountain areas in the upper reaches of Min River. Geographical information database of mountain areas in the upper reaches of Min River was established by GIS based on Geodatabase data model in this paper. On this basis, 1 ： 1000 000 and WGS_ 1984_ UTM_ Zone_ 48N coordinates were treated as reference to create a thematic map through using the function of data symbolization from GIS. Practice has proved that the application of GIS technology could make the information of mountain areas in the Upper Reaches of Min River digitalization and integration, which has theoretical significance and practical value for coordina ting mountain man-land relationship. Meanwhile, supported by database, GIS mapping makes drawing easy, fast and elegant and achieves the standardization and normalization of regional thematic map.
