Esta secuencia de comandos de Phyton de ejemplo publica una carpeta de imágenes en forma de servicio de imágenes.
En primer lugar, la secuencia de comandos crea un dataset de mosaico a partir de las imágenes. A continuación, se genera y se analiza un archivo de definición de servicio (SD) de borrador. El borrador de SD se crea usando la función arcpy.CreateImageSDDraft().
Si no se detectan errores en el análisis del borrador del SD, la secuencia de comandos continúa con la publicación del servicio.
