Remotely Piloted Aircraft Systems to Identify Pests and Diseases in Forest Species The global state of the art and future challenges FERNANDO COELHO EUGENIO, SALLY DEBORAH PEREIRA DA SILVA, ROBERTA APARECIDA FANTINEL, PABULO DIOGO DE SOUZA, BRUNNO MOREIRA FELIPPE, CASSIMO LACERDA ROMUA, AND EDUARDO MATHEUS ELSENBACH R emotely piloted aircraft systems (RPASs) have versatility of use and allow the attainment of images with high spatial resolution and low acquisition cost. Forestry researchers have a growing interest in developing research related to the use of images obtained by RPASs aimed at monitoring forest health. Digital Object Identifier 10.1109/MGRS.2021.3087445 Date of current version: 27 July 2021 The purpose of this review was to 1) study the temporal trends of the last decade in the use of RPASs in the areas of research on pests and diseases in forest species (PDFS) in terms of number of articles and countries as well as by a bibliometric analysis and 2) identify the main topics faced and keywords used in publications on PDFS with RPASs through a scientific mapping approach. We performed a systematic bibliometric review of published articles and ©SHUTTERSTOCK.COM /MEDIANA 320 0274-6638/22©2022IEEE IEEE GEOSCIENCE AND REMOTE SENSING MAGAZINE MARCH 2022http://www.SHUTTERSTOCK.COM
