Table 2 Advantages and disadvantages of ground-based and aerial-based types of platforms for cotton phenotyping
Platform type | Advantages | Disadvantages | References |
|---|---|---|---|
Ground-based | Structure stability, minimized bias in sample selection, good spatial resolution | Difficulty in maneuvering particularly when the plant row spacing is limited or when the soil is wet, long time to cover a whole experiment | Andrade-Sanchez et al. 2014; Araus and Cairns 2014; Condorelli et al. 2018; McCarthy et al. 2010; Xu et al. 2018b |
Aerial-based | Large coverage of sampling area, data collection can be done in a very short amount of time | Shorter flight time, lower payload, greater sensitivity to weather conditions, and weaker wind resistance, spatial resolution depends on speed and altitude | Han et al. 2018; Herwitz et al. 2004; Shi et al. 2016; Wang et al. 2018; Xu et al. 2019; Zhang and Kovacs 2012; Ziliani et al. 2018 |
