线状地物快速图斑化方法研究
Study on Rapid Mapping Method of Linear Features

线状地物转化为面状图斑是第三次全国土地调查中的主要任务之一，第三次土地调查中明确要求宽度超过2米的线状要素，通过建立缓冲区的形式进行线转面，确保不同等级线状地物的压盖关系、拓扑关系和不同宽度线性要素接边处平滑处理。基于此，本文提出了一种快速自动化处理的线状地物转图斑的方法，着重分析不同等级线状地物的重叠部分接边处理技术，并在ArcGIS平台上进行二次开发实现。
The transformation of linear features into planar maps is one of the main tasks in the third national land survey. The third land survey explicitly requires linear elements with a width of more than 2 meters. The line-turning surface ensures the gland relationship, topological relationship and smoothing of the linear elements at different levels of linear features. Based on this, this paper proposes a method for quickly and automatically processing the linear object maps, focusing on the analysis of overlapping edge joint processing techniques for different grades of linear features, and implementing secondary development on the ArcGIS platform.
