Smaller ships may be detected with decreasing wind speed, increasing incidence angle, and finer resolution. Narrow Far is expected to be a good compromise between spatial coverage and detection probability. Top of page Use of Landsat Thematic Mapper Thermal Infrared Data to Map Relative Temperature Zones Within the University of Idaho Experimental Forest D. R. Unger, J. J. Ulliman Relative forest ecosystem temperature zones, delineated using a single Landsat Thematic Mapper thermal infrared image, were found to be robust over time. Top of page Value Added Radarsat Products for Geoscientific Applications Th. Value-added products are then key points for their successful and regular use to bridge the gap between the technology and the end user communities.
Depth perception is related either to the water depth or the terrain elevation.
Kalmia angustifolia L . Top of page Using Ortho-Rectified SAR Imagery Acquired Over Rugged Terrain for Thematic Applications in Glacier Hydrology S. Adam, Th. Rectifying geometric errors in radar imagery of mountainous areas is often difficult because of significant distortions arising from the sensor's sensitivity to local topographic relief. The snow line positions and glacier boundary identified on the SAR imagery are within 50 to 75 m of their true locations based on data derived from field work. Satellite derived estimates of common measurements made in glacier hydrology, such as equilibrium line altitude, net mass balance, and accumulation area ratio, illustrate that the restitution accuracy of the ortho-rectification is very reliable.
