Geospatial semantics represent interrelated concepts and reasoning based on theoretical and applied perspectives. Concepts behind geographic knowledge representation are rooted in various disciplines, including language, logic, visual analytics, social theory, geospatial analysis, programming, and the humanities. The Commission on Geospatial Semantics (CGS) aims to advance research on this subject.

AutoCarto 2020 Workshop


An introductory tutorial on modeling aspects of geospatial semantics using Protégé design software


Presentations on current research by members and interested participants


Building a community by discussing plans for Commission activities

The CGS invites abstracts for its first annual workshop on theoretical and applied aspects of geospatial and cartographic ontologies to be held in conjunction with AutoCarto 2020. This half-day workshop will bring together expert and newly interested specialists and technologists to network and advance the broad study of geospatial informatics in geographic information. A range of potential topics are appropriate for the workshop and opportunities will be provided for those interested in the day’s agenda to register an interest or an issue to be included for discussion.

Scholars interested in presenting their research or participating in the session as a discussant are invited to submit their abstract or position paper at the web site linked on the workshop home page.
