Le géotraitement dans ArcGIS correspond à l'exécution d'un outil pour créer de nouvelles informations à partir d'informations existantes. En général, les résultats sont utilisés comme entrée dans d'autres outils pour automatiser un workflow mettant généralement en jeu la gestion des données, l'analyse spatiale, la conversion des données ou une combinaison de ces trois types de tâches. Le géotraitement est utilisé depuis de nombreuses années, Workstation ArcInfo étant l'un des premiers produits à fournir une riche collection d'opérations SIG, appelées commandes, et un cadre flexible permettant de les utiliser, appelé langage AML (Arc Macro Language).
ArcGIS 9 comportait un nouvel ensemble d'opérateurs SIG et une nouvelle structure destinée à leur utilisation. Un grand nombre des opérateurs sont familiers à un utilisateur de Workstation ArcInfo, tels que Agréger ou Découpage, car les noms ont été conservés autant que possible. ArcGIS 9.0 intégrait également la prise en charge de langages de script, tels que Python, qui permettaient de rédiger des workflows plus complexes souvent utilisés dans AML, mais faisant appel à des langages non propriétaires qui fournissaient des capacités supérieures à AML.
L'effort de conserver une relation entre les noms des commandes et des outils entre ArcInfo Workstation et ArcGIS 9 a également été étendu au modèle de script, dans lequel de nombreuses procédures restent semblables en nature. Là où cela était possible, la simplicité d'utilisation d'AML a été maintenue dans ArcGIS, comme pour répertorier les données d'un espace de travail ou décrire les propriétés d'un jeu de données. Le but est que tout utilisateur d'AML puisse apprendre rapidement à écrire un script de géotraitement avec ArcGIS.
Pour faciliter cette transition, les équivalents ci-dessous indiquent comment exécuter des fonctions AML, mais en utilisant Python. Toutes les fonctions et les directives AML ne s'appliquent pas nécessairement au nouveau modèle, car certaines étaient directement liées à l'environnement Workstation ArcInfo (telles que la fonction SHOW), tandis que d'autres (telles que LISTFILE) sont mieux prises en charge par Python que par les composants de géotraitement d'ArcGIS. De nombreux exemples utilisent les modules Python généraux conjointement avec la fonctionnalité Python d'ArcGIS.
