Let's try to find those common band combinations applied to BJ3N (Pléiades Neo 3 & 4)!
試著找出應用於BJ3N (Pléiades Neo 3 & 4)的那些常見波段組合！
BJ3N (Pléiades Neo 3 & 4) is an Earth observation satellite operated by Airbus with a spatial resolution of 1.2 meters in multispectral bands and 30 centimeters in panchromatic band. In this demonstration, the panchromatic data is not used to pansharpen the multispectral image. Working with multispectral images enables us to reveal information that is beyond human vision. For example, the Near Infrared (NIR) wavelength is commonly used to distinguish vegetation varieties and conditions because vegetation gives a strong reflection in this portion of the electromagnetic spectrum.
Let's try the following band combinations and know more about their application: (4,3,2), (6,4,3).
You could also try the following combinations to know more about each band and its application. (1,1,1), (2,2,2), (3,3,3), (4,4,4), (5,5,5), (6,6,6)

BJ3N (Pléiades Neo 3 & 4)是由Airbus操作的地球觀測衛星，可在可見光和NIR波段以1.2米的空間解像度提供圖像，並於全色波段以30厘米的空間解像度提供圖像。本次示範中，全色波段未有用於pansharen多光譜圖像。多光譜圖像使我們能夠揭示超出人類視覺範圍的信息。例如，近紅外(NIR)波長通常用於區分植被種類和狀況，因為植被在這一波段會產生強烈反射。
嘗試以下的波段組合，來了解更多關於這些波段組合的應用。 (4,3,2), (6,4,3)
您也可以嘗試以下的波段組合，來了解更多關於每個波段的功能和應用。 (1,1,1), (2,2,2), (3,3,3), (4,4,4), (5,5,5), (6,6,6)
