The Advanced ENVI for GEOINT course is a scenario-based follow-on to the ENVI Basics for GEOINT. It is designed for geospatial engineers, geospatial analysts, image analysts, or anyone wanting to produce advanced products to support various defense and intelligence operations. Each course represents a real-world scenario in which students use ENVI and IDL tools to solve a geospatial problem and to generate an output product.
