Forest, Crop and Grassland Leaf Area Index Estimation Using Remote Sensing: A Review of Current Research Methods, Sensors, Estimation Models and Accomplishments

Leaf area index (LAI) is an important parameter in plant ecophysiology; it can be used to quantify foliage directly and as a measure of the photosynthetic active and, thus, subject transpiration vegetation. The aim this paper was review work on remote sensing methods estimating LAI across different forest ecosystems, crops grasslands terms platforms, sensors models. To achieve aim, scholarly articles with title or keywords “Leaf Area Index estimation” “LAI were searched Google Scholar Web Science date range between 2010 2020. study’s results revealed that during last decade, use estimate map increased for natural forests. However, there still need more research concerning commercial forests grasslands, number studies remains low. Of 84 related forests, 60 24 In model types, empirical models most often followed by physical
