Cover Image

This cover image, courtesy of ERDAS®, Inc. Stereo Analyst, is the first practical and affordable solution for collecting 3-D data and viewing stereo imagery. Applications, including forestry, geology, local government planning, and telecommunications, can use Stereo Analyst in a variety of ways to generate accurate and precise 3-D GIS data and information from stereo imagery. Stereo Analyst seamlessly integrates with other ERDAS products, including IMAGINE OrthoBASE, a new Windows-based digital photogrammetry product for GIS users (see product review on page 567), and IMAGINE VirtualGIS, for 3-D visualization and analysis.

In this scene of Louisville, Kentucky, Stereo Analyst was used to collect the building features from stereo imagery. The 3-D features were then displayed in IMAGINE VirtualGIS and combined with an orthorectified image and high-resolution elevation data. A model layer was added to simulate tree placement in the image. The .15-meter resolution (6 inches) data were generated by a Zeiss RMK TOP15 aerial camera, and provided courtesy of Photo Science, Inc.
