GLCF editions of MODIS products differ from DAAC editions by coming in GeoTIFF format, geographic coordinates,
WGS84 datum, and a tiling
system designed to fit well with Landsat imagery.
|
| Overview |
|
MODIS (or Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard NASA's
Terra (EOS AM) and Aqua (EOS PM) satellites.
Terra's orbit around the Earth is timed so that it passes from north to south across the equator in
the morning, while Aqua passes south to
north over the equator in the afternoon. GLCF provides access to imagery collected from the Terra MODIS sensor,
in a product that is a composite of sixteen days worth of images. This composite has the benefit of eliminating most cloud cover
found in daily images. Note: the Collection 3, 32-day composites will remain online until replaced by the
Collection 4 and Collection 5 edition, 16-day composites.
