The C2 NDSI science product is the normalized difference between spectral bands green (G) and the shortwave infrared (SWIR). The NDSI is particularly useful for separating snow from vegetation, soils, and lithology endmembers.

The Normalized Difference Snow Index (NDSI) snow cover is an index that is related to the presence of snow in a pixel and is a more accurate description of snow detection as compared to Fractional Snow Cover (FSC).

2021年9月24日 · NDSI is a measure of the relative magnitude of the reflectance difference between visible (green) and shortwave infrared (SWIR). It controls variance of two bands (one …

NDSI is the normalized difference between spectral bands green (G) and shortwave infrared (SWIR). NDSI is useful for separating snow from vegetation, soils, and other spectral signatures, and is delivered as a single band.

Description of representative images Visualized NDSI over New Zealand, acquired on 2019-09-19. The NDSI script applied to Klagenfurt, Austria returning raw values.

NDSi 是任天堂继NDSL之后的又一款改进机型。 NDSi于2008年11月1在日本地区首发，首发价格为18900日元。

2014年1月1日 · Normalized-Difference Snow Index (NDSI) – normalized difference of two bands (one in the visible and one in the near-infrared or short-wave infrared parts of the spectrum) is used to map snow.

2023年7月25日 · Snow cover area is often estimated using the Normalized Difference Snow Index (NDSI) (Crane and Anderson, 1984; Dozier, 1984). Snow is highly reflective in the visible part of the electromagnetic spectrum and highly absorptive in the near-infrared or short-wave infrared band of the spectrum.

2010年5月6日 · The Normalized-Difference Snow Index (NDSI) has a long history. 'The use of ratioing visible (VIS) and near-infrared (NIR) or short-wave infrared (SWIR) channels to separate snow and clouds was documented in the literature beginning in the mid-1970s.

NDSI Normalized Difference Snow Index (NDSI) describes the Snow cover for any area. NDSI is calculated as a ratio between the visible (VIS) and mid-infrared (MIR). Process of NDSI NDSI …
