Dataset Description:
- SAR — synthetic aperture radar
- 2007-2010
- 42 sites in North and South America, and Greenland
- Monitoring networks include FLUXNET, Ameriflux, LTER, and the Greenland Climate Network (GC-Net)
- GeoTIFF format in Universal Transverse Mercator (UTM) projection and 15-meter resolution
Data File Information
Each scene is available in GeoTIFF format with a XML file containing metadata. A PDF document file is also available for each site and contains image-specific metadata, image analysts notes about channel assignments and colors, and a thumbnail of the SAR image. For sites with multiple images, only one thumbnail is included as images are quite similar in appearance.
Example PDF File:
Site Name: Baltimore Ecosystem Study (BES1)
GeoTIFF: Baltimore_Ecosystem_Study_20090728.tif
Imagery Date: 28-Jul-2009, 03:32:51
Location: Maryland
The SAR image has greens, pinks, blacks and some gray colors. By assigning the HH to the red and blue channels
and the HV polarization to the green, we get these slightly more intuitive colors. Green is tree canopy. Black is water.
Polarization: FBD 34.3 HH+HV
Bands: HH (red and blue)
Bands: HV (green)
