Estimation of soybean grain yield from multispectral high-resolution UAV data with machine learning models in west Africa by Alabi, T.R., Abebe, A.T., Chigeza, G., Fowobaje, K.R.

“…We acquired multispectral images through a Sequoia® camera aboard a senseFly eBee X UAV from five variety trials during the 2020 growing season in Nigeria. UAV-based spectral bands, canopy height, vegetation indices (VI), and texture features were generated by gray level co-occurrence matrix (GLCM) and integrated to predict crop grain yield using five machine learning (ML) regression models, including Cubist, Extreme Gradient Boosting (XGBoost), Stochastic Gradient Boosting (GBM), Support vector machine (SVM), and Random Forest (RF). …”

Surface runoff estimation over heterogeneous canal commands applying medium resolution remote sensing data with the SCS-CN method by Jayakody, Priyantha, Gamage, M.S.D.Nilantha

“…Land use/Land cover maps for four cropping seasons, Rabi 2004-05, Kharif 2005, Rabi 2006-07 and Kharif 2007 were derived using red and near infrared bands of MODIS 8 day products. The existing soil map was reclassified into hydrological soil groups and rainfall data were interpolated using the inverse distance method to represent the spatial rainfall values of each canal command. …”
