Remote sensing is the acquiring of information from a distance. NASA observes Earth and other planetary bodies via remote instruments on space-based platforms (e.g., satellites or spacecraft) and on aircraft that detect and record reflected or emitted energy.

2023年8月2日 · A graphic depiction of the International Space Station performing remote sensing. Remote sensing instruments are of two primary types— active and passive . Active sensors, provide their own source of energy to illuminate the objects they observe.

1999年9月17日 · Remote sensing is the science and art of identifying, observing, and measuring an object without coming into direct contact with it. This involves the detection and measurement of radiation of different wavelengths reflected or emitted from distant objects or materials, by which they may be identified and categorized.

2025年2月10日 · NASA radar imagery revealed that the active area of a decades-old landslide has grown following periods of heavy rainfall in 2023 and early 2024. Evaporite minerals from Searles Lake have similarities to minerals found on the asteroid Bennu.

Get a better idea of what we mean when we use basic Earth data terms like remote sensing or data processing level. Find all of the resources we have available for the Geographic Information Systems (GIS) community. Data in Action demonstrates Earth science data applications with interactive explanations as to how the work was accomplished.

NASA’s Applied Remote Sensing Training Program 38 Disadvantages of Remote Sensing • It is very difficult to obtain high spectral, spatial, temporal, and radiometric resolution all at the same time. • Large amounts of data in a variety of formats can lead to more time and processing.

Remote sensing is obtaining information about an object from a distance. There are different ways to collect data, and different sensors are used depending on the application. Some methods collect ground-based data, others airborne or spaceborne. What information do you need? How much detail? How frequently do you need the data?

The Earth Science and Remote Sensing Unit provides operations and science team functions for handheld camera crew photography of Earth from the ISS, interacts with other ISS sensor teams and working groups, coordinates ISS remote sensing response to natural disasters and other dynamic events through interaction with the United States Geological ...

2024年10月21日 · Learn how the science of remote sensing helps to increase our understanding of atmospheric and oceanic processes on Earth. In this STEMonstration, NASA astronaut Michael Barratt explores two remote sensors installed on the space station: the Earth Surface Mineral Dust Source Investigation (EMIT) and Global Ecosystems Dynamics Investigation (GEDI).
