Satellitenkarten

Satellitenkarten, also known as satellite imagery or satellite maps, are digital representations of Earth's surface or other celestial bodies captured by satellites. These images are acquired using sensors onboard spacecraft that orbit the planet. Different types of sensors can detect various parts of the electromagnetic spectrum, allowing for the creation of imagery that goes beyond what the human eye can see. This includes visible light, infrared, and microwave radiation.

The resolution of satellite maps varies greatly, ranging from very low resolution that shows broad geographical features to very high resolution that can identify individual buildings or objects. This resolution is determined by the capabilities of the satellite's sensors and the altitude of its orbit. Satellitenkarten are used for a wide array of applications. They are crucial for geographical information systems (GIS), urban planning, environmental monitoring, disaster management, agriculture, and scientific research. For instance, they help track deforestation, monitor ice caps, assess crop health, and aid in navigation.

The data collected by satellites can be processed and enhanced to create different types of maps, such as true-color images that resemble natural photographs, false-color images that highlight specific features like vegetation or water, and thematic maps that display particular data layers. Publicly accessible satellite imagery, such as that provided by Google Earth or Bing Maps, has made these powerful tools readily available to a broad audience for exploration and informational purposes.
