• Label: Modified normalized difference vegetation index (modified NDVI)
• Entity URI: https://w3id.org/APD/traits/trait_0020815
• Type: numeric
• Definition: A remote sensing [EnvThes:21762] index [NCIT:C25390] of whole plant [PO:0000003] vegetation status, which is a ratio [PATO:0001470] that considers the relative reflectance [EnvThes:21580] of red light versus short-wave infrared radiation (SWIR) [ENVO:21001214] off the plant canopy [ENVO:01001242], where a higher value indicates greater vegetation health. The formula is: (SWIR - Red) / (SWIR + Red).;A remote sensing index of whole plant vegetation status, which is a ratio that considers the relative reflectance of red light versus short-wave infrared radiation (SWIR) off the plant canopy, where a higher value indicates greater vegetation health. The formula is: (SWIR - Red) / (SWIR + Red).
• Additional comments: Modified NDVI is generally measured from Landsat data.
• units: {dimensionless}
• allowable range: 0.1 - 1 {dimensionless}
