COTTON CROP MONITORING USING MULTISPECTRAL OPTICAL SATELLITE IMAGERY

摘要

This paper details the validity of utilizing a color-based approach to monitor cotton crop readiness. By harnessing the TripleSat Constellation's 0.8m resolution multispectral imagery, this paper introduces how the maturing of cotton plants can be captured through non-conventional methodologies: employing the usage of the visible spectral bands to detect the change in the plantation's surface reflectance. Through the experiment, it was discovered that the red wavelength band (600-670nm) responded most significantly to cotton's phenological changes during the maturing phase. A hypothetical index is thus constructed to detect this physical change in cotton plantations. This allows for stakeholders to better monitor cotton readiness, and also to pre-empt incoming harvesting seasons over large areas simultaneously. This paper constitutes a portion of 21 AT's engagement with agricultural research, using high-resolution imagery to further improve this field of study, be it in enhanced crop monitoring, crop health management, soil studies, or land suitability evaluations.
