In a similar study, Zhang, Niu [23] noted that curled water stressed maize leaves saw an increase in the proportion of sunlit soil and higher temperature; thus, when Tc was extracted from thermal images, the Tc values were higher due to the influence of sunlit soil. During the reproductive...
Given that the cameras were not GPS-enabled, geotagging of the images was done with Field Extractor (Agribotix, Boulder, CO, USA) post-flight using time synchronization between the cameras and the internal clock of the GCS which is set to atomic time. This internal clock of the GCS is ...
