| 摘 要： | ArcGIS中文件地理数据库是常用数据格式。经常需要按其所辖单元区域批量裁剪输出地理数据。针对常规的手工操作不仅费时且易出错,本文提出基于ArcGIS ModelBuilder(模型构建器)建立模型工具的方法来实现地理数据库按区域自动批量的裁剪输出。该方法使用模型工具嵌套的方式,利用迭代要素类建立裁剪子模型工具对地理数据库中全部要素类依次进行裁剪,再将裁剪子模型工具嵌套到主模型工具中,使用迭代要素选择按区域逐个选择裁剪要素,直至完成所有区域对地理数据的裁剪输出。

| Abstract: | The file geodatabase in ArcGIS is a common data format.it is often necessary to batch clipping output the geographic data according to the unit region under its jurisdiction.Aiming at the conventional manual operation is not only time-consuming but also error-prone,this paper proposes a method based on ArcGIS ModelBuilder to build a model tool to realize automatic batch clipping output of geodatabase according to the region.The method using the nested model tool,clipping sub-models set up by using the iterative feature class tools for geodatabase by clipping all the feature classes,then the clipping sub-model tool nested to the main model tool,using iteration features in turn by region selection clipping features,until the completion of all regional clipping output of geographical data. |
