应用ArcGIS软件缩编1:5万土地利用现状图方法的探讨

Discussion on the Contracted Compilation Methods of 1:50000 Land-use Map based on ArcGIS

1:5万土地利用现状图缩编主要是对第二次全国土地调查数据的面状要素和线性要素进行合并或改变其表现方式,利用制图综合的方法将小于规范要求上图面积的图斑合并到相邻图斑或将宽度小于规范要求的道路、河流等线性要素改用线状符号表示,在上述数据处理过程中需要较多的人工操作,因此本文针对1︰5万土地利用现状图数据缩编过程中如何运用ArcGIS软件,从提高缩编工作效率方面进行讨论,提出针对面状要素和线性要素处理的两种方法,从而提高工作效率。

The contracted compilation of 1 ： 50000 land-use map is mainly focus on the merging or changing the expression complication of planar and linear elements from the second national land survey data. This process would depend on large manual operations such as substitution of linear symbols for the narrow roads or rivers that less than the rules which based on the cartographic generalization. This paper discusses how to improve the efficiency of contracted compilation and introduces two contracted compilation methods of 1 ： 50000 land-use map based on ArcGIS.
