GLCF: Landsat Tree Cover Continuous Fields (GLCF/GLS_TCC)

The Landsat Vegetation Continuous Fields (VCF) tree cover layers contain
estimates of the percentage of horizontal ground in each 30-m pixel covered
by woody vegetation greater than 5 meters in height. The data represent
three nominal epochs, 2000, 2005 and 2010, compiled from the NASA/USGS
Global Land Survey (GLS) collection of Landsat data. The product is derived
from all seven bands of Landsat-5 Thematic Mapper (TM) and/or Landsat-7
Enhanced Thematic Mapper Plus (ETM+), depending on the GLS image selection.

Tree cover, the proportional, vertically projected area of vegetation
(including leaves, stems, branches, etc.) of woody plants above a given
height, affects terrestrial energy and water exchanges, photosynthesis and
transpiration, net primary production, and carbon and nutrient fluxes. Tree
cover also affects habitat quality and movements of wildlife, residential
property value for humans, and other ecosystem services. The continuous
classification scheme of the VCF product enables better depiction of land
cover gradients than traditional discrete classification schemes.
Importantly for detection and monitoring of forest changes (e.g.,
deforestation and degradation), tree cover provides a measurable attribute
upon which to define forest cover and its changes. Changes in tree cover
over time can be used to monitor and retrieve site-specific histories of
forest change.

The dataset has been produced for three year epochs: 2000, 2005, 2010, with
an image in the collection for each available WRS2 path/row.
