This download files consists of two WebEx movies of the step-by-step, click-through process of using the batch tool to change the map model and the projection of multiple images, and the process of reprojecting multiple images. The movies are silent. The .bcf batch command file used in this example is included as well. To play the movies, please use the included WebEx player, atplay.exe.

Use this model to batch-subset using AOIs. You'll have to change the output variable to meet your needs, and you have to specify an AOI file for each input image.

Performing supervised classification on numerous input image files is often a tedious and time consuming process. However, assuming that the input imagery is radiometrically similar (i.e., it is derived from the same sensor type and has been processed to remove atmospheric and other scene to scene variations, such as by running it through the ATCOR 3 for ERDAS IMAGINE module to convert to reflectance) it is a simple task to use the ERDAS IMAGINE 2011 (or later) tools to batch the job of applying a standard signature file (or files) to multiple input image files in order to produce classified / thematic output categorized data layers. This process can even be broken down into jobs which can be parallel processed on a single computer or submitted to a distributed processing environment such as Condor. This document and .bcf file takes you through the steps necessary to create an ERDAS IMAGINE Batch Command File for executing multiple supervised classification jobs.

• -i defines input file, chosen from the batch input file selector
• -o defined output file, change in the Variables Tab of the Batch Tool or text editor before launching
• -cr defined target compression ratio (any integer is appropriate)
• -lossless defines a lossless compression, do not use -cr with this command
