LandsatSARBilderanalysen

LandsatSARBild is a designation for imagery acquired by the Synthetic Aperture Radar (SAR) instrument onboard the Landsat 8 satellite. Landsat 8, launched in 2013, is a joint NASA and USGS mission that provides continuous global data for land use and land cover mapping, as well as for monitoring environmental changes. While Landsat 8 is primarily known for its optical and infrared sensors, it also carries the Landsat SAR-B (Synthetic Aperture Radar) instrument. This instrument operates in the C-band microwave spectrum, allowing it to penetrate clouds and acquire imagery regardless of weather conditions or time of day.

The SAR data collected by Landsat 8 offers unique capabilities beyond optical imaging. It is sensitive to surface roughness, moisture content, and geometric properties of the terrain. This makes LandsatSARBild valuable for applications such as flood mapping, deforestation monitoring, soil moisture estimation, and disaster assessment, especially in regions prone to cloud cover. The data is processed and made available to researchers and the public through various archives, contributing to a broader understanding of Earth's surface dynamics.
