GEOG 581 is a graduate seminar for students who are concerned about the ethical implications and social impacts of geospatial technologies and methods. It traces the roots of Spatial Data Science Ethics in moral philosophy, professional ethics frameworks, and critical studies in the geospatial field. Students analyze ethical case studies and compare and critique relevant legal and policy issues. They evaluate the organizational ethics of firms and agencies (including current or potential employers) that provide spatial data science products and services, and they discuss a proposed “ethics of digital care” for leading balanced digital lives. Finally, they develop Term Projects that conceptualize and interrogate ethical issues related to their own research. Course activities include readings, case study analyses, presentations, discussions, and scholarly Term Project reports.
