    Has anyone experienced locational problems when using ASTER1b or ASTER1a georeferenced data in ENVI? Whatever I try... the imagery appears shifted too far south. Would like to determine if this problem is specific to ENVI software or ASTER products. Thanks, Jessica Mitchell Department of Geosciences Idaho State University

    Hi Jessica, ASTER 1B is typically fairly well georeferenced but if you are noticing a significant displacement, you might try orthorectifying via Map ->Orthorectification->ASTER. ASTER 1A data is not georeferenced at all, so Orthorectification should be performed. -mm
