State of Major Vegetation Indices in Precision Agriculture Studies Indexed in Web of Science: A Review

Vegetation indices provide information for various precision-agriculture practices, by providing quantitative data about crop growth and health. To a concise up-to-date review of vegetation in precision agriculture, this study focused on the major with criterion their frequency scientific papers indexed Web Science Core Collection (WoSCC) since 2000. Based topic “precision agriculture” combined “vegetation index”, found that United States China are global leaders total research application indices, while analysis adjusted country area showed much more homogenous development agriculture. Among these studies, based multispectral sensor frequently adopted studies than low-cost alternatives RGB sensor. The normalized difference index (NDVI) was determined as dominant index, 2200 year With existence improved shortcomings NDVI, such enhanced (EVI) soil-adjusted (SAVI), recognized potential enabling superior results to those NDVI future studies.
