Remote Sensing

Remote sensing involves acquiring information about the Earth's surface without physically touching it. This is typically done using sensors mounted on satellites, aircraft, or drones. These sensors capture data about the Earth's surface in the form of electromagnetic radiation, which is then processed to create images and other types of data products. Remote sensing is used for a wide range of applications, including environmental monitoring, agriculture, urban planning, and disaster management.

For example, satellite imagery can be used to monitor deforestation, track changes in land use, and assess the health of crops. Aerial photography can be used to create detailed maps of urban areas and monitor construction progress. Drones equipped with thermal cameras can be used to detect heat signatures and identify areas where energy is being lost. The data collected through remote sensing provides valuable insights into the Earth's surface, enabling us to make informed decisions about resource management, environmental protection, and urban development. Remote sensing data is often integrated with GIS to provide a comprehensive view of geographic information, allowing users to analyze spatial patterns and trends in a more holistic way. Open source tools like GRASS GIS (another OSGeo project) can be used for processing and analyzing remote sensing data.

Global Positioning System (GPS)

GPS, or Global Positioning System, is a satellite-based navigation system that provides precise location information anywhere on Earth. GPS receivers use signals from a network of satellites to determine their position, velocity, and time. GPS technology is used in a wide range of applications, including navigation, surveying, mapping, and tracking. From helping you find the nearest coffee shop to guiding airplanes across the ocean, GPS has become an integral part of modern life.
