Spot Imagery and 3-D Stereographic Analysis

Spot Panchromatic image of Central Florida. Geographic locals include: Lake Apopka (Upper Center); Orlando, FL ( Upper Right); Walt Disney World (Lower Right). Colored boxes indicate the locations of the 3-D anaglyphs shown below.

3-D Stereo Anaglyphs

The 3-D anaglyphs shown below were produced from a Spot panchromatic stereo pair by performing a registerstration and rotation of the right image (acquired 2/26/96) to the left image (acquired 2/25/96). The right looking image was then displayed in red and the left looking image displayed in green. The anaglyphs may be viewed with standard red-green 3-D glasses.
