在 ArcGIS 中,地理处理是执行某种工具以根据现有信息创建新信息的过程。结果通常用作后续工具的输入以实现工作流的自动化,而工作流通常包括数据管理、空间分析、数据转换任务或这三者的某种组合。从 ArcInfo Workstation 成为第一批能够提供一组丰富的 GIS 操作或命令以及一个灵活的框架(即 Arc 宏语言 (AML))来使用这些操作和命令的产品之一开始,地理处理已流行多年。
ArcGIS 9 引进了一组新的 GIS 运算符及一个使用这些运算符的新框架。由于尽量保留了名称,因此很多运算符都是 ArcInfo Workstation 用户所熟悉的,如“联合”或“裁剪”。ArcGIS 9.0 还新增了对 Python 等脚本语言的支持,从而使用非专有语言(具有比 AML 更强的功能)便可编写通常采用 AML 编写的比较复杂的工作流。
在 ArcInfo Workstation 和 ArcGIS 9 之间保留命令名称与工具名称之间的关系这一作法也已扩展到脚本编写模型中,因此许多过程实际上也是相似的。可能的话,在 ArcGIS 中保留了 AML 的易用之处,例如在工作空间中列出数据或描述数据集的属性等。目的是使所有 AML 用户都能快速掌握使用 ArcGIS 编写地理处理脚本的方法。
为协助过渡,以下等效语句概括了使用 Python 执行 AML 函数的方式。未必所有 AML 函数和指令都适用于新模型,因为某些函数与 ArcInfo Workstation 的环境直接相关(如 SHOW 函数),而其他函数(如 LISTFILE)只有 Python 自身可以更好地支持,而 ArcGIS 地理处理组件则无法支持。许多示例均结合 ArcGIS Python 功能来使用通用的 Python 模块。
