Evaluation of pre/post-fire differenced spectral indices for assessing burn severity in a Mediterranean environment with landsat thematic mapper [PDF]
, 2011 In this study several pre/post-fire differenced spectral indices for assessing burn severity in a Mediterranean environment are evaluated. GeoCBI (Geo Composite Burn Index) field data of burn severity were correlated with remotely sensed measures, based ...

Normalized difference vegetation index for drought monitoring
MAUSAM, 1987 In this study remote sensing technique has been adopted to monitor changes in vegetation cover during the crop growing season and assess the drought conditions. Normalized difference of Landsat Multispectral Scanner (MSS) near Infrared (NIR) band (0.8-1.1 um) and red band (0.6-0.7 um) spectral data has been found useful to monitor the change in crop ...

Chlorophyll fluorescence, photochemical reflective index and normalized difference vegetative index during plant senescence [PDF]
Journal of Plant Physiology, 2016 The relationship between the Photochemical Reflectance Index (PRI), Normalized Difference Vegetation Index (NDVI) and chlorophyll fluorescence along senescence was investigated in this work. Reflectance and radiance measurements were performed at canopy level in grass species presenting different photosynthetic metabolism: Avena sativa (C3) and Setaria

Omni-Akuatika, 2022 Mangrove ecosystem in Segara Anakan Lagoon (SAL) Cilacap as a typical and specific semiclosed estuary. SAL is dominated by many species like as Rhizophora spp., Sonneratia spp., Bruguiera spp., Avicennia spp., and other species. The normalized different vegetation index (NDVI) and dominant vegetation index (DVI) are a suitable method to support the ...
