Crop Monitoring And Yield Estimation Using Polarimetric Sar And Optical Satellite Data In Southwestern Ontario, Chunhua Liao

Electronic Thesis and Dissertation Repository

Optical satellite data have been proven as an efficient source to extract crop information and monitor crop growth conditions over large areas. In local- to subfield-scale crop monitoring studies, both high spatial resolution and high temporal resolution of the image data are important. However, the acquisition of optical data is limited by the constant contamination of clouds in cloudy areas. This thesis explores the potential of polarimetric Synthetic Aperture Radar (SAR) satellite data and the spatio-temporal data fusion approach in crop monitoring and yield estimation applications in southwestern Ontario.

Firstly, the sensitivity of 16 parameters derived from C-band Radarsat-2 polarimetric …
