- ENVI, the Environment for Visualizing Images, is an advanced,
- full-featured remote sensing image processing application. It combines a
- robust suite of image processing functions with state-of-the-art radar
- and spectral analysis routines to provide you with a powerful tool that
- can be used from desktop PCs, Macintoshes, or Unix workstations.
-
- ENVI's open file architecture allows you to read and analyze virtually any
- image type and share the data with others. Its intuitive graphical user
- interface introduces new users to the variety of applications quickly and
- easily. Experienced users can easily customize the interface to accommodate
- specialized analysis requirements.
-
- Custom image processing routines can be rapidly created and run in ENVI
- using IDL, Research Systems' comprehensive data analysis and visualization
- software. With ENVI, you get the unique combination of advanced image
- processing, an intuitive graphical interface, and full extensibility.

- Unique ENVI Features
- --------------------
-
- Efficient, array-based image math:
- Harness IDL's powerful tools for numerical analysis of imagery including
- FFTs, algebraic & trigonometric functions, and spline interpolation.
-
- Innovative visualization tools:
- Take advantage of state-of-the-art methods for representing and displaying
- your imagery, including XYZ profiles, 3D perspective views, image draping
- surface plots, and interactive scattergrams.
-
- Linked windows and dynamic overlays:
- Simultaneously display registered images from different data sets and
- switch among overlays to quickly compare and evaluate your results.
-
- Advanced analysis of spectral data:
- Built-in tools for efficient handling of multispectral and hyperspectral
- imagery can be integrated with spectral libraries and processing techniques
- to create interactive scatter plots, stacked profiles, spectral-curve math,
- and linear spectral unmixing.
-
- Advanced radar tools:
- Process and analyze standard radar data types such as ERS-1/ERS-2, JERS-1,
- and RADARSAT. Synthesize images from synthetic aperture radar data.
- Extract polarization signatures and process the images using a wide suite
- of radar-specific tools.
-
- Versatile annotation:
- With ENVI's advanced annotation functions, you can easily create
- publication-quality images and plots for presentation to your colleagues.
- Annotation features include: multiple fonts, line styles and thicknesses,
- fill patterns, symbol tables, interactive positioning, and resizing.
- Map composition objects include: pixel, latitude/longitude, and map
- coordinate grids; scale bars, declination diagrams and north arrows; map
- keys and classification legends; and image insets.
-
- User extensibility:
- Now you have the power to write your own processing algorithms using the
- powerful IDL language. Custom functions can be added to ENVI's
- comprehensive menus for convenient point-and-click access.
