水污染在线监测系统的探究

针对传统地形图生产软件不能兼顾制图表达和GIS空间分析的问题,介绍ArcGIS的制图表达功能,并以制作1:2 000地形图制图表达库为例,充分利用ArcGIS制图表达功能,并根据测绘地形图生产的特殊要求,自行研发程序对ArcGIS制图效果进行扩展,完成了 1:2 000制图表达库在ArcGIS中的制作,解决了DLG数据在符号化环节的制图和建库一体化的问题,提高了GIS制图效率和丰富了复杂地物表达能力.

Research on the Map Symbol Library Based on the ArcGIS Representation

Traditional map production software does not take into account the representations and GIS spatial analysis problems,introduced ArcGIS representation function,and to produce 1 : 2000 map representation library as an example, take advantage of ArcGIS representation function,and based on the special requirements of the Representation,develop program to extend ArcGIS representation geometric effects,completed 1 : 2000 representation library,resolve the integra-tion of the DLG data mapping and spatial data,improve the efficiency of the GIS mapping,enrich the expression ability of complex object.
