Analyze spatial relationships with explicit coordinate, geometry, data-provenance, and join assumptions.
Build a careful workflow for querying and joining geographic features, then connect desktop GIS operations with a spatial database. Learners distinguish geometry predicates, coordinate reference systems, and the grain of joined records; they also examine how boundary choices and source provenance shape an analysis. The assignments use invented or appropriately licensed geographic examples, require checks for invalid or mismatched geometries, and avoid treating a map or spatial association as causal evidence. Verify source terms and coordinate metadata before reusing any real dataset.
Plan a spatial query or join by naming its geometry predicate, coordinate reference system, and expected output grain. Identify projection, geometry-validity, boundary, and duplicate-match checks needed before interpreting a spatial result. Document spatial-data provenance and communicate limits of geographic aggregation and association.
Basic familiarity with tables, maps, and either a GIS interface or introductory Python is helpful. No specific software is required for the written activities. Use geographic data whose license and terms permit your intended use, and avoid exposing precise locations of vulnerable people or sensitive sites.
