The Global Land Cover Facility (GLCF) provides earth science data and
products to help everyone to better understand global environmental systems.
In particular, the GLCF develops and distributes remotely sensed satellite
data and products that explain land cover from the local to global
Primary data and products available at the GLCF are free to anyone via FTP.
Online datasets may be accessed electronically through the Earth
Science Data Interface (ESDI).
The majority of users accessing GLCF datasets (certainly not all) come from
the following communities:
Computer Science: data mining, data fusion, computer vision
GLCF research focuses on determining land cover and land cover change
around the world. Land cover is the discernible vegetation, geologic,
hydrologic or anthropogenic features on the planet's land surface. These
features, such as forests, urban area, croplands and sand dunes, can be
measured and categorized using satellite imagery. Land cover change can be
assessed by comparing one area with two images taken at different dates.
Determining where, when, how much and why change occurs with land cover is a
crucial scientific concern. It is imperative that appropriate tools be made
available to better manage and adapt to change.
