This presentation describes the idea of spatialSTEM for teaching map analysis and modeling fundamentals within a mathematical/statistical context that resonates with science, technology, engineering and math/stat communities.  The premise is that “maps are numbers first, pictures later” and we do mathematical things to mapped data for insight and better understanding of spatial patterns and relationships within decision-making contexts …from Where is What graphical inventories to a Why, So What and What If problem solving environment.

This map-ematical approach focuses on analytical tools used in spatial reasoning by a non-GIS community instead of traditional “GIS mechanics” of data acquisition, storage, retrieval, query and display of map features directed toward GIS specialists.  The goal is to get the STEM communities to “think with maps” and infuse direct consideration of spatial patterns and relationships into their endeavors, as an alternative for spatially-aggregated math/stat procedures that assume uniform or random distribution in space.
