Bei der Geoverarbeitung in ArcGIS wird ein Werkzeug ausgeführt, um auf der Grundlage von vorhandenen Daten neue Informationen zu erstellen. Die Ergebnisse fungieren i. d. R. als Eingabe für weitere Werkzeuge, um auf diese Weise Workflows zu automatisieren. Typischerweise umfasst dies das Datenmanagement, die räumliche Analyse, die Konvertierung von Daten oder eine Kombination dieser drei Vorgänge. Die Geoverarbeitung findet bereits seit einer Reihe von Jahren Anwendung, wobei ArcInfo Workstation eines der ersten Produkte war, das eine breite Palette von GIS-Vorgängen (als Befehle bezeichnet) sowie eine flexible Umgebung für deren Ausführung, die so genannte AML (Arc Macro Language), bietet.
In ArcGIS 9 wurden neue GIS-Operatoren und eine neue Umgebung für ihre Verwendung eingeführt. Mit vielen der Operatoren sind Benutzer von ArcInfo Workstation bereits vertraut (beispielsweise mit "Vereinigen (Union)" oder "Ausschneiden"), da deren Namen weitgehend beibehalten wurden. Seit ArcGIS 9.0 unterstützt ArcGIS zudem Skriptsprachen wie Python, sodass auch komplexe, häufig in AML verwendete Workflows programmiert werden können, wobei nicht proprietäre Sprachen eingesetzt werden, die einen größeren Funktionsumfang als AML bieten.
Die Beibehaltung einer Beziehung zwischen Befehls- und Werkzeugnamen zwischen ArcInfo Workstation und ArcGIS 9 wurde auch auf das Skriptmodell ausgeweitet, wobei die Merkmale von vielen Prozeduren beibehalten wurden. Die Benutzerfreundlichkeit von AML wurde nach Möglichkeit in ArcGIS beibehalten, beispielsweise beim Auflisten von Daten in einem Workspace oder Beschreiben der Eigenschaften eines Datasets. Damit wurde beabsichtigt, dass AML-Benutzer sich schnell mit dem Verfassen von Geoverarbeitungsskripten in ArcGIS vertraut machen können.
Um diesen Übergang zu erleichtern, wird im Folgenden erläutert, wie AML-Funktionen unter Verwendung von Python ausgeführt werden können. Nicht alle AML-Funktionen und -Direktiven finden sich im neuen Modell, da sich einige von ihnen direkt auf die Umgebung in ArcInfo Workstation beziehen (z. B. die Funktion "SHOW"), während andere (wie "LISTFILE") besser von Python selbst als von den ArcGIS-Geoverarbeitungskomponenten unterstützt werden. In vielen Beispielen werden allgemeine Python-Module in Verbindung mit der ArcGIS Python-Funktionalität verwendet.
