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.

FAQ

How do I convert an HDF/HDF-EOS file into binary format?
To convert HDF or HDF-EOS files into binary format you can use the hdp utility, which is part of the HDF4 distribution available from the HDF Group. How you install HDF4 depends on your operating system. Full instructions for installing and using hdp on Mac/Unix and... read more
