Satellite Characteristics: Orbits and Swaths - Canada
As a satellite revolves around the Earth, the sensor "sees" a certain portion of the Earth's surface. The area imaged on the surface, is referred to as the swath. Imaging swaths for spaceborne sensors generally vary between tens and hundreds of kilometres wide.

Chapter 2.2 Satellite Characteristics: Orbits and Swaths - Kangwon
As a satellite revolves around the Earth, the sensor "sees" a certain portion of the Earth's surface. The area imaged on the surface, is referred to as the swath. Imaging swaths for spaceborne sensors generally vary between tens and hundreds of kilometres wide.
When a satellite looks down on the Earth from space, it only sees a small part of the surface at a time during each orbit. But after many orbits, it eventually sees all of the surface so that a full map can be put together. This figure shows one ‘swath’ of …
Remote sensing applications generally use near polar, sun-synchronous, near circular orbits. The near polar orientation helps to attain near global coverage, whereas the near circular orbit helps to attain uniform swath for the images.
What Are Swaths? - Florida State University
1999年1月29日 · The most likely data sets to be used for oceanography and meteorology applications are not swath data, but the level 3 data sets, which are gridded on longitude-latitude axes. However, for applications requiring a single image from one or two satellite passes, the swath data provide the finest spatial resolution.
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?
Remote Sensing | NASA Earthdata
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.
Swath Width - an overview | ScienceDirect Topics
'Swath width' refers to the coverage area on the Earth's surface that can be imaged by a remote sensing system in a single pass. It is a key parameter that determines the extent of the area that can be observed at once.
