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.
