Multidimensional arrays naturally match the structure of spatio-temporal satellite data and can provide a clean modeling process for complex spatio-temporal analysis over large datasets. ...
We use arrays as a unified data structure for the modeling process, R to execute the analysis, and an array database management system to scale computation. ...
Thus we "tidy data" (Wickham, 2014) by organizing data as multidimensional arrays, and use array data to provide a clean, communicable, and scalable way for spatio-temporal data analysis. ...
