This demo theater session will provide an introduction to the Image Management Workflows, a collection of documentation and sample Python scripts designed to automate the process of creating, populating, and configuring mosaic datasets. These methods and samples have been applied to build and maintain large image collections, such as the LandsatLook catalog of all Landsat scenes (more than 2 million records), and the Landsat 8 image services which are updated with up to 300 GB of new imagery, in a fully automated process, every 24 hours.
