+- Graduate students and researchers from fields specializing in geographic data including Geography, Remote Sensing, Planning, GIS and Spatial Data Science
 - Academics and post-graduate students working with geographic data --- in fields such as Geology, Regional Science, Biology and Ecology, Agricultural Sciences, Archaeology, Epidemiology, Transport Modeling, and broadly defined Data Science --- who require the power and flexibility of R for their research
 - Applied researchers and analysts in public, private or third-sector organizations who need the reproducibility, speed and flexibility of a command-line language such as R in applications dealing with spatial data as diverse as Urban and Transport Planning, Logistics, Geo-marketing (store location analysis) and Emergency Planning
