Overview and Current Status of Remote Sensing Applications Based on Unmanned Aerial Vehicles (UAVs)
TL;DR: An overview of different areas of remote sensing applications based on unmanned aerial platforms equipped with a set of specific sensors and instruments is presented, each independent from the others so that the reader does not need to read the full paper when a specific application is of interest.
Journal ArticleDOI
A survey on technologies for automatic forest fire monitoring, detection, and fighting using unmanned aerial vehicles and remote sensing techniques
TL;DR: Technologies related to UAV forest fire monitoring, detection, and fighting are briefly reviewed, including those associated with fire detection, diagnosis, and prognosis, image vibration elimination, and cooperative control of UAVs.

Individual tree detection from Unmanned Aerial Vehicle (UAV) derived canopy height model in an open canopy mixed conifer forest
Midhun Mohan,Carlos A. Silva,Carine Klauberg,Prahlad Jat,Glenn P. Catts,Adrián Cardil,Andrew T. Hudak,Mahendra Dia +7 more
TL;DR: From the results, it can be concluded that ITD can be performed with an acceptable accuracy (F > 0.80) from UAV-derived CHMs in an open canopy forest, and has the potential to supplement future research directed towards estimation of above ground biomass and stem volume from Uav-imagery.
