3D elevation model of the Ohgaki Region, near Nagoya, Japan, as surveyed by Optech's ALTM (Airborne Laser Terrain Mapper) on February 14, 2002. The upper image shows terrain including vegetation; the lower image shows bare earth. Eroded gullies, hidden by foliage in the upper image, are clearly visible in the center of the lower image with vegetation removed. Data were captured with a 33kHz system at altitudes ranging from 1,000 to 1,500 meters. Optech is the world leader in the development and manufacture of airborne laser mapping systems; for more information, please visit www.optech.on.ca.

581 True Orthophoto Generation of Built-Up Areas Using Multi-View Images
Jiann-Yeou Rau, Nai-Yu Chen, and Liang-Chien Chen

Experimental results indicate that the proposed scheme can significantly reduce hidden and shadow defects.

589 Large-Area Land-Cover Mapping through Scene-Based Classification Compositing
B. Guindon and C.M. Edmonds

A method is described to create large-area land-cover products through the compositing of independently classified Landsat scenes and to assess product accuracies based upon classification consistency analyses of inter-scene overlap regions.

597 Textural and Contextual Land-Cover Classification Using Single and Multiple Classifier Systems
Olivier Debeir, Isabelle Van den Steen, Patrice Latinne, Philippe Van Ham, and Eléonore Wolff

The accuracy of land-cover clasification can be improved not only by the introduction of textural and contextual information but also by the use of a multiple classifier system.

607 Evaluation of Narrowband and Broadband Vegetation Indices for Determining Optimal Hyperspectral Wavebands for Agricultural Crop Characterization
Prasad S. Thenkabail, Ronald B. Smith, and Eddy De Pauw

Twelve spectral bands and their bandwidths that provide optimal agricultural crop characteristics in the visible and near-infrared portion of the spectrum were determined.

623 Predicting Mammal Species Richness and Abundance Using Multi-Temporal NDVI
Boniface O. Oindo

Interannual average NDVI and its variability (standard deviation) were correlated with large mammal species richness and abundance of individuals at a landscape scale in Kenya.
