Satellitmätning

Satellitmätning, also known as satellite remote sensing, is a scientific method used to collect data about the Earth's surface and atmosphere from space. This technology involves the use of satellites equipped with various sensors and instruments to measure and record different types of electromagnetic radiation reflected or emitted by the Earth. The data collected can be used for a wide range of applications, including environmental monitoring, climate research, agriculture, forestry, urban planning, and disaster management.

Satellitmätning provides several advantages over traditional ground-based measurements. It allows for the collection of data over large areas and in remote or inaccessible regions, enabling comprehensive and consistent monitoring. Additionally, satellite data can be acquired repeatedly over time, facilitating the detection of changes and trends. The technology also offers the advantage of being able to measure parameters that are difficult or impossible to observe from the ground, such as sea surface temperature, atmospheric composition, and vegetation health.

The data collected by satellites are processed and analyzed using specialized software and algorithms to generate maps, images, and other visualizations. These products can be used to support decision-making processes in various fields, such as identifying areas at risk of natural disasters, assessing the impact of climate change, and optimizing resource management practices. Satellitmätning plays a crucial role in our understanding of the Earth system and its dynamics, contributing to the development of sustainable solutions for a changing planet.
