PE&RS April 2002

Cover Image
This months’ cover depicts Washington, DC, USA, which is the location for the XXII Congress of FIG, held in conjunction with the ACSM-ASPRS 2002 Conference and Technology Exhibition. This vertical image of central Washington, in which the Washington Monument and White House can be clearly seen, is a 61-centimeter, pan-sharpened natural color image acquired by the recently launched QuickBird spacecraft of DigitalGlobe®. The left hand, or western, portion of the image has been color-coded based on digital elevation data obtained from the STAR-3i airborne Synthetic Aperture Radar system of Intermap Technologies. The small image is a perspective view of the same scene created using the 3D analysis and visualization tools of IMAGINE VirtualGIS®. The images are provided courtesy of Leica Geosystems and the image processing was performed using the company’s ERDAS IMAGINE® software.
