Land cover maps are tools that provide vital information about the Earth's land use and cover patterns. They aid policy development, urban planning, and forest and agricultural monitoring. [ 1][ 2] The systematic mapping of land cover patterns, including change detection, often follows two main approaches: Remote sensing satellite image ...
The Moderate Resolution Imaging Spectroradiometer ( MODIS) is a satellite-based sensor used for earth and climate measurements. There are two MODIS sensors in Earth orbit: one on board the Terra ( EOS AM) satellite, launched by NASA in 1999; and one on board the Aqua (EOS PM) satellite, launched in 2002. MODIS has now been replaced by the VIIRS ...
Global Forest Watch. Global Forest Watch (GFW) is an open-source web application to monitor global forests in near real-time. GFW is an initiative of the World Resources Institute (WRI), with partners including Google, USAID, the University of Maryland (UMD), Esri, Vizzuality and many other academic, non-profit, public, and private organizations.
Land use. Global distribution of land used for agriculture. Land use involves the management and modification of natural environment or wilderness into built environment such as settlements and semi-natural habitats such as arable fields, pastures, and managed woods. Land use by humans has a long history, first emerging more than 10,000 years ...
Google Earth. Google Earth is a computer program that renders a 3D representation of Earth based primarily on satellite imagery. The program maps the Earth by superimposing satellite images, aerial photography, and GIS data onto a 3D globe, allowing users to see cities and landscapes from various angles. Users can explore the globe by entering ...
WRI has partnered with Google Earth Engine to develop Dynamic World, a near real-time (NRT) application that uses high-resolution satellite images to do land use land cover (LULC) classification. Dynamic World identifies areas of land and water such as wetlands, forests, trees, crops and urban areas.
Land use, land-use change, and forestry ( LULUCF ), also referred to as Forestry and other land use ( FOLU) or Agriculture, Forestry and Other Land Use ( AFOLU), [ 3] [ 4]: 65 is defined as a " greenhouse gas inventory sector that covers emissions and removals of greenhouse gases resulting from direct human-induced land use such as settlements ...
Land cover is the physical material at the land surface of Earth. Land covers include flora, concrete, built structures, bare ground, and temporary water. Earth cover is the expression used by ecologist Frederick Edward Clements that has its closest modern equivalent being vegetation. [1] : 52 The expression continues to be used by the United ...
