Equivalentes Python a las funciones AML
El geoprocesamiento en ArcGIS es la ejecución de una herramienta para crear información nueva a partir de la información existente. Por lo general, los resultados se utilizan como entrada en herramientas posteriores para automatizar un flujo de trabajo, que comúnmente incluye tareas de administración de datos, de análisis espacial, de conversión de datos o una combinación de las tres. El geoprocesamiento existe desde hace muchos años y ArcInfo Workstation fue uno de los primeros productos en proporcionar un gran conjunto de operaciones o comandos SIG y un marco flexible para su utilización, el Lenguaje de macros ARC (AML).
ArcGIS 9 introdujo un nuevo conjunto de operaciones SIG y un nuevo marco para su utilización. Muchos de los operadores son conocidos para cualquier usuario de ArcInfo Workstation, como Combinación o Recortar, ya que se mantuvieron los nombres cada vez que fue posible. ArcGIS 9.0 también agregó soporte para lenguajes de secuencia de comandos, como Python, para que los flujos de trabajo más complejos utilizados a menudo en AML también se pudieran escribir utilizando lenguajes no propietarios que proporcionaran más capacidades que AML.
El esfuerzo para mantener una relación entre los nombres de comando y herramienta entre ArcInfo Workstation y ArcGIS 9 también se extendió al modelo de secuencia de comandos, y la naturaleza de muchos procedimientos se mantuvo similar. Cuando fue posible, se mantuvo la facilidad de uso de AML en ArcGIS, como la enumeración de datos en un espacio de trabajo o la descripción de propiedades de un dataset. El objetivo es que cualquier usuario de AML pueda aprender rápidamente a escribir una secuencia de comandos de geoprocesamiento con ArcGIS.
Para ayudarlo en esta transición, los siguientes equivalentes señalan cómo realizar las funciones AML con Python. No todas las funciones y directivas AML se aplican necesariamente al nuevo modelo, ya que algunas se relacionaron en forma directa al entorno de ArcInfo Workstation (como la función SHOW), mientras que otras (como LISTFILE) tienen mayor compatibilidad con Python que con los componentes de geoprocesamiento de ArcGIS. Muchos ejemplos utilizan los modelos generales de Python junto con la funcionalidad de Python de ArcGIS.
