The Need for Orthorectification

Satellite and aerial imagery is used increasingly in GIS and scientific applications for the rich information it provides about a geographic area.   If you use imagery as a source for information, you’ve encountered a need to perform orthorectification -  the process of accurately registering imagery to ground coordinates and geometrically correcting it to remove distortions that happen during image capture.

A Rigorous Solution from ENVI

Previously, methods for orthorectifying imagery required extensive knowledge of the process and complex software systems that were not necessarily available to the typical image consumer.  Now, the ENVI Orthorectification Module delivers a trusted, rigorous orthorectification method and robust capabilities, all distilled into an easy-to-use workflow.

This solution creates a seamless data transition, easily taking you from data ingest to orthorectification and further exploitation of results using your ENVI software. Designed for use by non-expert and expert users alike, the wizard-based interface guides users through orthorectification steps to quickly produce accurate results.

Trusted Method for Rigorous Orthorectification

The method in the ENVI Orthorectification Module is based on the mathematical model for rigorous orthorectification designed by worldwide ortho experts, Spacemetric. Spacemetric’s engineers have worked closely with satellite and aerial providers for many years, optimizing their model to accurately work with today’s most popular airborne and satellite sensors.

This extensive research and development has produced a solid, truly rigorous method that is widely accepted as an industry standard in image orthorectification technology.  Spacemetric's highly optimized software allows imagery users to produce high quality results quickly. Since this trusted method is now combined with the image processing and analysis capabilities in ENVI, you can trust that your orthorectification results are scientifically accurate and of the highest quality.
