基于ArcGIS Representation的地形图制图表达库研究

Research on the Map Symbol Library Based on the ArcGIS Representation

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Arc GIS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Arc GIS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Arc GIS制图效果进行扩展,完成了1∶2 000制图表达库在Arc GIS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。

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