Use ENVI Modules to quickly and easily perform highly-specialized tasks that require advanced image analysis tools.
Feature Extraction Module
Find and extract specific objects of interest from all types of imagery with the ENVI Feature Extraction Module (ENVI FX). User-friendly tools enable users 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.
3D point cloud feature extraction is also available in this module. Feature identification can be performed on an entire point cloud scene or a user-defined subset of a scene – providing accurate information in a fraction of the time. Features users can extract include buildings, trees, and power lines.
The inherent flexibility of ENVI FX lets users modify parameters and data at any stage of the process. Designed specifically for GIS users and fully integrated with ESRI’s ArcGIS® software, ENVI FX includes unique step-by-step workflows to walk through previously complex image analysis tasks.
DEM Extraction Module
The ENVI DEM extraction module is used to quickly and easily create spatially accurate DEMS of geospatial imagery. A step-by-step, guides users through the process, producing accurate and robust models from virtually any airphoto or stereo satellite images with RPCs, including those from pushboom sensors such as WorldView 2, ASTER, IKONOS, OrbView-3, QuickBird and SPOT 1-5. These tools let users view anaglyph images, measure building or mountain heights, edit DEM values, and extract 3D features.
Atmospheric Correction Module
Remove atmospheric interference from imagery with the ENVI Atmospheric Correction Module (ENVI ACM). The ENVI ACM module delivers accurate, scientific details creating a true, reliable representation of a specific image scene. This flexible solution offers either advanced, physics-based techniques or more of an on-the-fly method for real-time data processing and works with both multispectral and hyperspectral data.
Register imagery to ground coordinates and geometrically correct them to remove distortions that happen during image capture with the ENVI Photogrammetry 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 GIS products.
This module also generates synthetic 3D point clouds and a DSM 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.
Read, edit, and deliver NITF files using the ENVI NITF Module, certified by the Joint Interoperability Test Command (JITC). The ENVI NITF/NSIF Module was tested by the JITC and recommended for full compliance and registration to complexity level 7 for NITF 2.1 and complexity level 6 for NITF 2.0 – the highest awarded for each format.
Digital Surface Model generated from SPOT-7 stereo-data and corresponding land displacements derived from SAR differential interferometry.
ENVI Opticalscape generates Digital Surface Models (DSMs) and orthorectified images from spaceborne and UAV data while giving users the industry leading tools for imagery preparation and data fusion.
Opticalscape UAV processes multiple stereo images to create orthorectified mosaic images while correcting for sensor orientation. The DSM generation is based on the most advanced algorithms and automated ortho image mosaicking. To facilitate the image orientation, images must include a coarse platform position, however, attitude data are not mandatory.
Opticalscape Spaceborne processes optical stereo and tri-stereo images acquired from satellites for the generation of DSMs and ortho images. The DSM generation is based on the most advanced algorithms and takes into account new sensor characteristics.
Fusion of Opticalscape and SARscape Products
High-resolution spaceborne or UAV DSMs can be ingested into SARscape Interferometric Stacking module to derive precise land displacement maps. Opticalscape and SARscape fuse DEM data generated from SAR and optical sensors. This data fusion is unique to ENVI Opticalscape and greatly improves the accuracy of the DEM product. Futhermore, the fusion considers the sensor characteristics rather than simply averaging the different heights (top).
Minimize Losses to Maximize Yields
ENVI CROP SCIENCE
Agricultural operations work on razor thin margins. One key to profitability is being able to use the minimum amount of crop inputs while simultaneously maximizing yields. This is often easier said than done since conventional field inspection methods are time consuming and inefficient. Missing a small area of pest or insect infestation can result in a big loss come harvest, and over fertilizing can be just as costly as using too little fertilizer over the long term.
Satellite and UAV imagery offers an efficient and effective way to survey small to large scale farming operations to assess overall crop health. Remote sensing techniques can then be used to analyze aerial imagery to pinpoint areas of crop stress and determine exactly what is needed to remedy the situation. This type of analysis provides actionable information to determine when, where, and how much water, pesticide, and fertilizer is needed to produce a healthy crop.
