EARTH RESOURCES MGMT. & GEOSCIENCES CATEGORY

The title of this scene is "The City of Guelph from a Bird's eyes." The scene was created using GEOREF GIS software by Minglin Li of GEOREF Systems Ltd. The digital aerial imagery was collected using the MEIS (Multispectral Electro-optical Imaging Sensor) camera which was originally developed by the Canadian Center for Remote Sensing (CCRS). The imagery was corrected to the geodetic control points on the ground and then wrapped onto the digital evaluation model (DEM).

The entire process was done on a Silicon Graphics R4000 Indigo XS24 workstation. The GEOREF GeoIMAGE software was used to perform the geometric and radiometric correction. The corrected image was then mapped onto an exaggerated DEM in the 3D rendering tool GoeTIN (another GEOREF product). As a final touch, the sky was created using Silicon Graphics Showcase software.
