two color-coded shaded relief maps will be delivered.The shaded relief models will be illuminated from orthogonal directions with a sun elevation no greater than 45 degrees.Data will be gridded at a grid size that is approximately twice the mean horizontal footprint of the beam at nadir(e.g...

Off-nadir angles of 0 to 16掳 were considered for a 25. m diameter footprint diameter.Footprint diameters in the range of 25m to 30m were optimal for estimates of maximum forest height (R2 of 0.95 and RMSE of 3m). As expected, the contribution of vegetation height to the vertical ...
off-nadir using Cloud Absorption Radiometer (CAR) data collected during the Smoke, Clouds, and Radiation-Brazil (SCAR-B) experiment conducted in 1995. For the data analyzed and for the view angles tested, results seem to suggest that the reflectance (rho)0.47 and (rho)0.67 are predictable ...

Off-nadir imagery (captured not directly overhead) is the fastest to acquire post-disaster, making it ideal for disaster management scenarios. However, the changes in viewing angles result in shadows and occlusions, making damage detection more d...
This end-to-end System Performance Model is especially designed for long stand-off airborne detection with large off-nadir viewing angles. It takes into account most of the components within the entire imaging chain. The model divides the end-to-end imaging chain into three parts: the ...
Where viewed at high solar incident angles or emission angles, rough surfaces and those containing mixtures of surface units (e.g., rock and sand, rock and dust) below the pixel resolution of the instrument display varied amounts of sub-pixel anisothermality due to the viewing geometry and ...
