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 MODIS has now been replaced by the VIIRS ...
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 ...
A remote sensing software is a software application that processes remote sensing data. Remote sensing applications are similar to graphics software, but they enable generating geographic information from satellite and airborne sensor data. Remote sensing applications read specialized file formats that contain sensor image data, georeferencing ...
In current usage, the term remote sensing generally refers to the use of satellite - or aircraft-based sensor technologies to detect and classify objects on Earth. It includes the surface and the atmosphere and oceans, based on propagated signals (e.g. electromagnetic radiation ).
The mapping of glaciers is facilitated by remote sensing in contrast with carrying heavy equipment to dangerous icy land. Some notable applications include mapping of clean-ice and debris-covered glaciers, glacier fluctuation records, mass balance and volume change studies to aid generating topographic map and quantitative analysis.

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 ...
Sci. The Journal of Photogrammetry, Remote Sensing and Geoinformation Science (formerly Photogrammetrie, Fernerkundung, Geoinformation - PFG) is an academic journal published by Springer on behalf of the German Society for Photogrammetry, Remote Sensing and Geoinformation [ de] about photogrammetry, remote sensing, and geoinformation science.
