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 ...
Google Earth is a web and 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 ...
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 ...
The different spectral bands used on satellites in the Landsat program provide many applications, ranging from ecology to geopolitical matters. Land cover determination is a common use of Landsat imagery around the world. [ 23 ]
One of the first large scale Google Earth Engine projects was a study of global forest change. Researcher Matthew Hansen had been mapping global land cover since the mid-1990s, first at South Dakota State University, then at the University of Maryland, but lacked sufficient high-resolution data.
[58] 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.
CLUE model. CLUE (Conversion of Land Use and its Effects) model is a spatially explicit land-use change model developed to simulate future land-use and land-cover changes, including urban expansion, deforestation, land abandonment, and agricultural intensification. [1][2][3] CLUE model is a dynamic modeling framework which simulates land-use ...
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.
