ENVI

ENVI 4.4 streamlines your image analysis workflow, and allows you to quickly and efficiently perform common routines, such as working with vector layers, pan sharpening images, conduct change detection, and much more.

And, ENVI 4.4 gives you additional spectral processing and analysis capabilities - the core capabilities that make ENVI the choice of geospatial professionals worldwide.

A More Efficient Image Processing Workflow

Capabilities in ENVI 4.4 keep the image analysis workflow in mind, introducing new tools that allow you to perform both basic and advanced image processing routines easily and quickly, regardless of your experience level.

Advanced Spectral Image Processing

Introducing the new vegetation suppression algorithm for ENVI, allowing you to:

• Interpret geologic and urban features
• Perform linear feature enhancement
• Identify items hidden under open and closed vegetation canopies
• Detect vehicles or encampments underneath vegetation

SPEAR Tools
ENVI 4.4 introduces SPEAR Tools – a set of tools that allow defense and intelligence image analysts to perform both common and advanced image processing routines easily and quickly.

SPEAR tools allow you to easily:

• Pan-sharpen images
• Detect lines of communication
• Find watercraft
• Measure relative water depth
• Conduct TERCAT (Terrain Categorization)
• Perform change detection
• Assess vegetation delineation and stress detection

Produce spectral analogues to find similar materials.

Vector Layers in ENVI Zoom
ENVI 4.4 makes performing common vector layer tasks faster and more convenient by allowing you to access functionality through the intuitive ENVI Zoom interface to:

• Import vector layers from virtually any source
• Edit vector layers based on project requirements
• Export vector layers to an ESRI Shapefile

Additional Visualization Tools in ENVI Zoom
The ENVI Zoom optional interface now includes several new tools designed that help make your workflow more efficient, including:

• "Up is Up" button - Rotates an image so that buildings are aligned vertically with your monitor
• "Go To" tool - Takes you automatically to an area defined by the coordinate locations you enter
• Path history - Turn your view box path history on or off, and clear it on demand
• Crosshair tool - See exact locations of a particular pixel or area of interest

ENVI Feature Extraction Module
ENVI 4.4 introduces support for the new ENVI Feature Extraction Module. This object-based, add-on functionality to ENVI allows you to quickly, easily, and accurately find and identify features of interest in high resolution geospatial imagery. Now, you can conveniently find particular features across large images, extract vector layers for further analysis, and classify images as outputs to be used in reports or analyses.

Introducing the ENVI Feature Extraction Module

Quickly and easily extract features from imagery with this object-based tool.

Today you need to find and identify features of interest within geospatial imagery. But, the process of manually locating and digitizing these features can be complex and time consuming, and spectral content is often limited, reducing the accuracy of standard classification methods.

The new ENVI Feature Extraction Module allows you to quickly, easily and accurately extract features from high resolution imagery. This add-on module to ENVI uses object-based image analysis technology so you can extract features from readily available pan and multi-spectral imagery and data.

Fast & Repeatable

Save time over traditional feature extraction methods:
• Segment an image and quickly view the results in a Preview Window to assess the accuracy of the segmentation, rather than waiting for the full image to process,
• Quickly adjust the segmentation scale and preview your product as many times as needed prior to full image processing

Accurate

Get the accurate results you need:
• Unlike traditional pixel-based approaches to feature extraction, which use the spectra of each pixel to accurately classify imagery, the ENVI Feature Extraction Module uses an object-based approach to identify and define features, providing you with accurate results even with limited bands.
• The method makes it an accurate tool for use with all kinds of imagery and data types, including pan and multi-spectral imagery.

Easy-To-Use

The ENVI Feature Extraction Module makes it easy to find what you need in your imagery:
• Intuitive workflows and preview screens for ingesting images, performing segmentations, and initiating processing.
• The new Preview Window allows you to quickly see processing results and readily allows for adjustments and changes.
• In most cases you will only need to interact with a single parameter and the tool will automatically take care of the rest.

Convenient

The ENVI Feature Extraction Module:
• Allows you to extract features from pan and multi-spectral imagery - the most widely available imagery today, and
• Because it is an add-on module to the ENVI product, users can perform all feature extraction, image processing, analysis and visualization tasks in a single product.

Application

The ENVI Feature Extraction Module replaces manual digitization processes and is ideal for:
• Finding particular features across large images
• Adding new vector layers to your geodatabases
• Classifying images as outputs to be used in reports or analyses
