摘　　要：在地理数据处理中,裁剪数据是常见操作。当有多个矢量数据裁剪多个栅格数据时,常规的数据裁剪工具耗时费力。为了解决这一问题,本文采用ArcMap中的ModelBuilder构建了多矢量多栅格批量裁剪工具。该工具应用镶嵌功能,将构建的子模型工具添加到主模型中,实现了多个迭代过程的运行。经过试验对比研究,当处理的数据相同时,先迭代矢量数据后迭代栅格数据模型工具用时最短,调用次数最少。这表明,该工具可解放人力,大大提高生产作业效率。Clipping data is a common operation in geographic data processing.When we use multiple vector data to clip multiple raster data,conventional data clipping tools are time-consuming and laborious.In order to solve this problem,this paper uses ModelBuilder in ArcMap to build a multi-vector and multi-raster batch clipping tool.The tool applies the mosaic function,adds the constructed submodel tool to the main model,and realizes the operation of multiple iterative processes.After experimental comparison and research,when the data to be processed are the same,iterating the vector data first and then iterating the raster data model tool takes the shortest time and calls the least number of times.This shows that the tool can liberate manpower and greatly improve the efficiency of production operations.
