A Spatiotemporal GIS Framework Applied to the Analysis of Changes in Temperature Patterns
Abstract This research develops a new temporal Geographic Information System (GIS) framework and applies it to compare General Circulation Model (GCM) products and reanalysis datasets in order to discern differences in patterns and locations of change as a proof of concept. The proposed framework in...
