Definición
La anchura de barrido se refiere a la distancia horizontal recorrida por un sensor de satélite al captar imágenes de la superficie terrestre. La anchura de la franja puede variar en función del sensor y de la órbita del satélite, pero suele ser de varios kilómetros.
The swath width is important because it determines the area that can be imaged by the satellite in a single pass. For example, a satellite with a swath width of 10 km can capture an area of 10 km x 100 km (assuming a 10:1 length-to-width ratio) in a single pass.
The swath width can also affect the spatial resolution of the satellite image. For example, a sensor with a resolution of 1 meter per pixel will produce a higher resolution image over a narrower swath width than over a wider swath width.
Swath width can also affect the frequency with which a satellite captures images of a particular area. Satellites with wider swath widths may capture images less frequently than those with narrower swath widths, but they may cover a larger area overall.
The choice of swath width depends on the specific needs of the application. For example, a satellite used for monitoring crops may require a wider swath width to cover a larger area, while a satellite used for urban planning may require a narrower swath width to capture more detail in densely populated areas.
In summary, swath width is an important characteristic of satellite sensors that determines the area imaged in a single pass and can affect the spatial resolution and frequency of image capture.
