Find and extract specific objects of interest from all types of imagery and LiDAR with the ENVI Feature Extraction Module (ENVI FX). User-friendly tools enable you to extract features from geospatial imagery based on the object’s spatial, spectral, and texture characteristics and identify them as objects like vehicles, buildings, roads, coastlines, rivers, lakes, and fields.
The inherent flexibility of ENVI FX lets you modify parameters and data at any stage of the process to get the specific information you need from your imagery to make more informed decisions. For example, in the military to find tanks or airstrips; in urban development to determine the extent of housing sprawl; or in local government to track highway assets.
Designed specifically for GIS users and fully integrated with ESRI’s ArcGIS software, ENVI FX includes unique step-by-step workflows that walk you through previously complex image analysis and LiDAR processing tasks.
Remove atmospheric interference from your imagery with the ENVI Atmospheric Correction Module (ENVI ACM). Whether you require an advanced, physics-based technique, or more of an on-the-fly method for real-time data processing, ENVI ACM offers a flexible solution that delivers the accurate and scientific detail you need.
ENVI ACM treats each image and its atmospheric imprint individually to create a unique model that is a true, reliable representation of a specific image scene. The ENVI Atmospheric Correction Module works on both multispectral and hyperspectral data and automatically supports today's most frequently used sensors.
Register imagery to ground coordinates and geometrically correct them to remove distortions that happen during image capture with the ENVI Photogrammetry Module (formerly the Orthorectification Module). This Module delivers a trusted, rigorous orthorectification method with robust capabilities. A wizard-based interface guides users through orthorectification steps to quickly produce expert-level results regardless of experience level. This solution creates a seamless data transition, easily taking you from data ingest through orthorectification with the option to export results for further analysis or inclusion in your GIS products.
This module also generates synthetic 3D point clouds from spaceborne optical imaging platforms via multi-ray photogrammetry techniques that involve feature detector pixel correlation and dense image matching. This functionality produces LAS format output files that can be used with the wide variety of point cloud visualization and processing tools available in ENVI. Users can take advantage of large commercial imagery archives and also use this capability to create point cloud and terrain products where flying airborne LiDAR is not feasible or would be cost-prohibitive.
