What is NDVI (Normalized Difference Vegetation Index)?
https://gisgeography.com/ndvi-normalized-difference-vegetation-index/
WEBMar 10, 2024 · NDVI always ranges from -1 to +1. But there isn’t a distinct boundary for each type of land cover. For example, when you have negative values, it’s highly likely that it’s water. On the other hand, if you have an NDVI value close to +1, there’s a high possibility that it’s dense green leaves.

WEBNov 27, 2018 · NDVI values range from +1.0 to -1.0. Areas of barren rock, sand, or snow usually show very low NDVI values (for example, 0.1 or less). Sparse vegetation such as shrubs and grasslands or senescing crops may result in moderate NDVI values (approximately 0.2 to 0.5). High NDVI values (approximately 0.6 to 0.9) correspond to …

Normalized difference vegetation index - Wikipedia
https://en.wikipedia.org/wiki/Normalized_difference_vegetation_index
WEBThe index is easy to interpret: NDVI will be a value between -1 and 1. An area with nothing growing in it will have an NDVI of zero. NDVI will increase in proportion to vegetation growth. An area with dense, healthy vegetation will have an NDVI of one. NDVI values less than 0 suggest a lack of dry land. An ocean will yield an NDVI of -1.

Landsat Normalized Difference Vegetation Index
https://www.usgs.gov/landsat-missions/landsat-normalized-difference-vegetation-index
WEBNDVI is used to quantify vegetation greenness and is useful in understanding vegetation density and assessing changes in plant health. NDVI is calculated as a ratio between the red (R) and near infrared (NIR) values in traditional fashion: (NIR - R) / (NIR + R) In Landsat 4-7, NDVI = (Band 4 – Band 3) / (Band 4 + Band 3).

WEBAug 30, 2019 · In most cases, NDVI values between 0.2 and 0.4 correspond to areas with sparse vegetation; moderate vegetation tends to vary between 0.4 and 0.6; anything above 0.6 indicates the highest possible density of green leaves.

Normalized Difference Vegetation Index (NDVI)
https://www.landscapetoolbox.org/remote-sensing-methods/normalized-difference-vegetation-index-ndvi/
WEBValues of NDVI can range from -1.0 to +1.0, but values less than zero typically do not have any ecological meaning, so the range of the index is truncated to 0.0 to +1.0.

A Guide to Normalized Difference Vegetation Index (NDVI)
https://www.arable.com/blog/a-guide-to-normalized-difference-vegetation-index-ndvi/
WEBThis vegetative index is commonly used as both a crop status monitor and a decision-making tool. NDVI plots visually represent a plant’s canopy cover and growth cycle, allowing you to easily compare NDVI values between fields and seasons to ensure your crop is healthy and reaches the expected growth milestones.
