Geo-Generalist Era: Where Spatial Meets Everything

Today’s geospatial thinkers are increasingly “geo-generalists”—individuals who apply spatial thinking across many disciplines. From public health to marketing, from climate science to logistics, GIS is becoming a core competency for professionals in a wide range of fields. This theme celebrates the expanding influence of GIS and the professionals who bridge disciplines to solve complex, real-world challenges using spatial insight. It goes beyond a GIS person only working in the mapping department.
