Visual Information SolutionsENVI Orthorectification ModuleOrthorectify Your Imagery Quickly and Easily.

Rigorous Orthorectification.Simple Workflow. Trusted Method.The Need for OrthorectificationSatellite and aerial imagery is used increasingly in GIS and scientific applications for the rich information itprovides about a geographic area. If you use imagery as a source of information, you've encountered aneed to perform orthorectification - the process of accurately registering imagery to ground coordinatesand geometrically correcting it to remove distortions that occur during image capture.A Rigorous Solution from ENVIPreviously, methods for orthorectifying imagery requiredextensive knowledge of the process and complex softwaresystems that were not necessarily available to the typicalimage consumer. Now, the add-on ENVI OrthorectificationModule delivers a trusted, rigorous orthorectification methodand robust capabilities, all distilled into an easy-to-use workflow.This solution creates a seamless data transition, easily takingyou from data ingest to orthorectification and furtherexploitation of results using your ENVI software. Designedfor use by non-expert and expert users alike, the wizardbasedinterface guides users through orthorectificationsteps to quickly produce accurate results.Trusted Method for Rigorous OrthorectificationThe method in the ENVI Orthorectification Module is based on the mathematical model for rigorousorthorectification designed by worldwide ortho experts, Spacemetric. Spacemetric's engineers haveworked closely with satellite and aerial providers for many years, optimizing their models to accuratelywork with today's most popular airborne and satellite sensors.This extensive research and development has produced a solid, truly rigorous method that is widelyaccepted as an industry standard in image orthorectification technology. Spacemetric's highly optimizedsoftware allows imagery users to produce high quality results quickly. Since this trusted method is nowcombined with the image processing and analysis capabilities in ENVI, you can trust that yourorthorectification results are scientifically accurate and of the highest quality.Orthorectify your imagery quickly and easily.ENVI
