  • Remote Sensing

Vegetation monitoring has been one of the main focal points of remote sensing study since remote sensing research began. Many vegetation indices, using red and infrared reflectance, have been devised. The Perpendicular Vegetation Index (PVI), Ratio Index and Normalized Vegetation Index are among the well known indices of this type. The Perpendicular Vegetation Index, proposed by Richardson and Wiegand (1977), was defined as the distance from the soil line on a scatter plot of near infrared (NIR) versus red reflectance. The pixel vectors of bare land in such plots vary with soil moisture content. The PVI was developed as a vegetation index to effectively monitor the vegetation biomass without being affected by differences in soil background.
