利用ArcGIS10建模工具实现放线测量成果的自动处理

Automatic Processing of Alignment Measurement Outcome Based on ArcGIS Modeling Tools

城市地下管线放线测量成果包括放线路由shapefiles数据,放线桩点平面坐标成果和测区范围控制点信息等内容。这部分工作通常是人工操作完成,通过研究发现利用ArcGIS10建模工具ModelBuilder可自动实现上述处理,其主要经过了CAD要素的shapefile格式化和矢量数据的空间分析处理两大步骤。这一自动化处理体现了ArcGIS软件的空间分析功能与CAD图形编辑能力的互补。

Urban underground pipeline alignment measurement outcome includes shapefile data of alignment routing , planar coordinate outcome of alignment pile points and control points information of surveying area .This task is usually completed by manual operation .This paper researches that this process can be realized automatically through using Arc-GIS10 modeling tools ,this method mainly includes CAD features shapefile formatting and spatial analysis process of vec -tor data.This paper reveals complementarity of ArcGIS spatial analysis function and CAD graphics editing ability .
