NASA Image2000 is an image processing software package available on multiple platforms, designed to bring high-end scientific image processing capabilities to the standard desktop computer. (See Minimum Specifications in Section 1.2 for limitations for Mac and Unix operating systems.) Developed to meet the needs of educators, NASA Image2000 supports the display, analysis and processing of satellite imagery.

NASA Image2000 Functionality
The functionality built into NASA Image2000 was designed to provide the capability for the display and analysis of geo-coded satellite imagery. Users can perform standard image processing tasks, similar to those available in general graphics packages. In addition, the system provides other less common functions, including (but not limited to) the following:
Display pixel intensity, pixel location relative to the image, latitude and longitude values and their corresponding projected coordinates (for geo-coded images only)
Non-destructive image annotation including text, symbols, lines and polygons,
Processing based on a region of interest (ROI),
Image math using scalars and other images,
Compute image statistics,
Generate a histogram,
Measurement options including distance, area, perimeter, and angle,
Apply map projections,
Create, edit, and animate a stack of images, and
Create a montage from a stack or from open images
