What is Global land cover Facility?
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 scales.
How many land covers are there in the world?
The Land Area of the World is 13,003 million ha. 4,889 million ha are classified as ‘agricultural area’ by the FAO (this is 37.6% of the Land Area).

Can humans change land cover and land use?
Changes in land cover can occur in response to both human and climate drivers. Land use is also changed by both human and climate drivers. Land-use decisions are traditionally based on short-term economic factors.
Can different types of land cover have the same land usage?
Land cover refers to the surface cover on the ground, whether vegetation, urban infrastructure, water, bare soil or other; it does not describe the use of land, and the use of land may be different for lands with the same cover type.
How much land on Earth is unused?
They conclude that just over 50% of Earth’s land surface can be classified as having low human influence or being untouched completely, with a range of 48-56% depending on the type of human influence map used.
Which country has the most free land?
Land use statistics by country
| Rank | Country | Arable land (%) |
|---|---|---|
| — | World | 10.6 |
| 1 | India | 52.8 |
| 2 | United States | 16.8 |
| 3 | Russia | 7.3 |
How do I find my land cover?
Land cover can be determined by analyzing satellite and aerial imagery. Land use cannot be determined from satellite imagery. Land cover maps provide information to help managers best understand the current landscape. To see change over time, land cover maps for several different years are needed.
What is the global land cover facility?
The Global Land Cover Facility (GLCF) is an operational research and development project housed in the Department of Geographical Sciences, within the College or Behavioral and Social Sciences, at the University of Maryland.
Where can I find Landsat GeoCover images?
The University of Maryland’s Global Land Cover Facility (GLCF) offers thousands of Landsat scenes and derived data products. The GLCF archive includes all of the Landsat GeoCover data, therefore, the archive contains at least one image from any where in the world (within Landsat coverage boundaries), except for Antarctica.
What is the global forest cover change project?
The Global Forest Cover Change project, funded by the NASA MEaSUREs program, is mapping changes in Earth’s forest cover at sub-hectare resolution using the NASA/USGS Global Land Survey datasets circa 1975, 1990, 2000 and 2005.
What is the dynamic land cover map at 100 m resolution?
The Dynamic Land Cover map at 100 m resolution (CGLS-LC100) is a new product in the portfolio of the CGLS and delivers a global land cover map at 100 m spatial resolution. The CGLS Land Cover product provides a primary land cover scheme.
