The application of small unmanned aerial systems for precision agriculture: a review
Chunhua Zhang,John M. Kovacs +1 more
TL;DR: To provide a reliable end product to farmers, advances in platform design, production, standardization of image georeferencing and mosaicing, and information extraction workflow are required and the farmer should involve in the process of field design, image acquisition, image interpretation and analysis.
Journal ArticleDOI
Ethnobiology, socio-economics and management of mangrove forests: A review
Bradley B. Walters,Patrik Rönnbäck,John M. Kovacs,Beatrice Crona,Syed Ainul Hussain,Ruchi Badola,Jurgenne H. Primavera,Edward B. Barbier,Farid Dahdouh-Guebas,Farid Dahdouh-Guebas +9 more
TL;DR: There is growing research interest in the ethnobiology, socio-economics and management of mangrove forests as discussed by the authors, with harvesting efforts and impacts concentrated in stands that are closer to settlements and easiest to access (by land or by sea).
Journal ArticleDOI
Large-scale dieback of mangroves in Australia’s Gulf of Carpentaria: a severe ecosystem response, coincidental with an unusually extreme weather event
Norman C. Duke,John M. Kovacs,Anthony D. Griffiths,Luke Preece,Duncan J. E. Hill,Penny Van Oosterzee,Jock Mackenzie,Hailey S. Morning,Damien Burrows +8 more
TL;DR: The most severe and notable instance ever reported of sudden and widespread dieback of mangrove vegetation was reported in Australia's remote Gulf of Carpentaria in 2015 and 2016 as mentioned in this paper, where the cause was not fully explained but the timing was coincident with an extreme weather event; notably one of high temperatures and low precipitation lacking storm winds.
Journal ArticleDOI
Assessment of red-edge vegetation indices for crop leaf area index estimation.
Taifeng Dong,Jiangui Liu,Jiali Shang,Budong Qian,Bao-Luo Ma,John M. Kovacs,Dan Walters,Xianfeng Jiao,Xiaoyuan Geng,Yichao Shi,Yichao Shi +10 more
TL;DR: In this paper, the authors explored the potential of vegetation indices (VIs) for crop leaf area index (LAI) estimation, with a focus on comparing red-edge reflectance based (RE-based) and the VIS-based VIs.
Journal ArticleDOI
Object-oriented crop mapping and monitoring using multi-temporal polarimetric RADARSAT-2 data
Xianfeng Jiao,John M. Kovacs,Jiali Shang,Heather McNairn,Dan Walters,Baoluo Ma,Xiaoyuan Geng +6 more
TL;DR: In this paper, an object-oriented classification of polarimetric Synthetic Aperture Radar (PolSAR) data to map and monitor crops using 19 RADARSAT-2 fine beam polarIMetric images of an agricultural area in North-eastern Ontario, Canada.
