Unlock the information in your imagery quickly and easily

We understand that just making an image processing and analysis solution available to you as a GIS user is only part of the answer – you also need a software solution that integrates seamlessly with your current workflow. ENVI EX was specifically designed around the needs of GIS users, and made to be fully interoperable with ArcGIS data and layers. This tight integration with ArcGIS allows you to:

• Easily exchange data files and layer files between ArcGIS and ENVI EX by simply selecting an image in ArcGIS and dragging and dropping it into ENVI EX.
• View and interact with ArcGIS layers in ENVI EX while viewing vector information with the same symbology, styling and rendering as ArcGIS.
• Execute image processing tasks in ENVI EX, make changes to the parameters on the fly, and see the changes as you move between the two products.
• The GeoLink to ArcMap feature links the ENVI EX display to the ArcMap Data View so that the center geolocation in both products remain the same while panning through imagery.

ENVI EX. The image processing software choice for GIS users. Now you can easily add information from imagery to your GIS with a product designed specifically with your needs in mind, and with seamless integration to the tools you already trust. Allowing you to:

ENVI EX supports imagery types gathered from today’s popular satellite and airborne sensors including panchromatic, multispectral, hyperspectral, radar, thermal, LiDAR and more. ENVI EX can read over 70 data formats and includes J2K, GeoTIFF, and optional JITC-compliant NITF support. ENVI EX also allows you to easily drag and drop files from Windows® Explorer, search results, and ArcGIS, making it easy to access and integrate information into ENVI from other desktop applications.

Display and View Your Imagery and Data

The desktop toolbox and layer manager in ENVI EX give you the tools you need to visualize your imagery and data, and to create representations that are clear and easily interpreted. Advanced manipulation tools allow you to stretch, sharpen, blend, rotate, adjust brightness, transparency and contrast, create histograms, and add annotations to your imagery.

The ENVI EX unique portal view allows you to display an image or an ArcGIS layer, select an area of interest, and quickly visualize that selected area using the manipulation tools. ENVI EX even gives you access to vector editing tools, such as a rectangulator and smoother, to “clean up” your visualizations and make features in your image more true to life.

We work closely with GIS professionals to determine the image processing and analysis procedures that are most needed for you to add important information to your GIS applications. ENVI EX now delivers the methods that have been trusted by image scientists for years in easy to use image processing routines and image analysis workflows that produce results you can count on.

Image Processing Tools

ENVI EX provides image processing routines to prepare your imagery and data for further advanced analysis. These routines allow you to:

• Pan Sharpen an Image: The process of taking low resolution multispectral data and combining it with high resolution panchromatic data to get a spatially sharpened, multispectral result.
• Detect Anomalous Features: Find features in an image that differ from the overall image scene.
• Suppress Vegetation: Minimize the visual effects of vegetation in your imagery to highlight non-vegetation materials.

Image Analysis Workflows

ENVI EX automated image analysis workflows are easy to use, stepping you through each stage of image processing and analysis with intuitive dialog boxes and predetermined parameters based on typical desired outcomes. The workflows also offer enough flexibility to allow you to interactively modify parameters and data at various stages of the process. ENVI EX automated workflows allow you to:

• Extract Features from an Image
  The Feature Extraction Workflow automatically isolates and extracts features of interest in an image for further analysis or output as a layer to your GIS.
• Detect Change in an Area Over Time
  The Change Detection Workflow compares images taken at different times or with different sensors, and allows you to visualize change over time in an area of interest.
• Classify Materials or Land Cover
  The Classification Workflow provides supervised and unsupervised methods for grouping pixels in an image into categories in order to identify and extract materials or land cover.
• Orthorectify Images for Analysis
  The RPC Orthorectification Workflow accurately registers imagery to a digital elevation map and geometrically corrects it to remove distortions that happen during image capture.

Preview the results of these workflows in the flexible portal, where you can easily view results before processing the entire image. And, the portal will update dynamically and quickly with processing results as you move it over your image.

Once you’ve completed your image analysis workflow, ENVI EX makes it easy to output and share your results. The output capabilities are seamless with your GIS workflow, giving you a variety of ways to share the information from your imagery including:

• Chip to print, to a file, or to PowerPoint: Easily capture any screenshot of your processed data and send it to the printer, to a file for future use, or to a Microsoft® PowerPoint® file.
• Save to the geodatabase or to a shapefile: With ENVI EX you can easily save directly to the geodatabase, or save your results as a new shapefile for use in other applications.
• Output Using ArcGIS Print Dialog: The ENVI EX solution gives you complete integration between printing and viewing. With its tight integration with ArcGIS, ENVI EX results can be output as map products, using the popular ArcGIS map templates and printing dialogs directly from the ENVI interface.
