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. 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 ...
It is a joint NASA / USGS program. On 23 July 1972, the Earth Resources Technology Satellite was launched. This was eventually renamed to Landsat 1 in 1975. [1] The most recent, Landsat 9, was launched on 27 September 2021. The instruments on the Landsat satellites have acquired millions of images. The images, archived in the United States and ...
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.

Fields are shaded yellow and brown, water blue, and urban surfaces red. Land cover is the physical material on the land surface of Earth. Land covers include plant communities, buildings and structures, pavements, agricultural fields, and temporary waterbodies such as detention ponds. Earth cover is the expression used by ecologist Frederick ...
Keyhole Markup Language ( KML) is an XML notation for expressing geographic annotation and visualization within two-dimensional maps and three-dimensional Earth browsers. KML was developed for use with Google Earth, which was originally named Keyhole Earth Viewer. It was created by Keyhole, Inc, which was acquired by Google in 2004.
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 MODIS has now been replaced by the VIIRS ...
