Data Acquisition and Processing
Sensor or Instrument Description
The Multi-angle Imaging SpectroRadiometer (MISR), on board NASA's Terra platform, views Earth at nine widely spaced angles via radiometrically and geometrically calibrated images in four spectral bands at each of the nine angles, to provide global images with high spatial detail. Global spatial sampling is provided at 275 and 1100 meters. These images provide accurate measures of the brightness, contrast, and color of reflected sunlight.
