GeoTemporal Informatics: A look at a piece of the puzzle
Arie CroitoruThe University of AlbertaDept. of Earth and Atmospheric Sciences
What is “solved”?
• Data collection and access– Spatial data, event logs
• Data storage/management• Understanding the
importance of spatiotemporal dynamics
2NSF GeoInformatics workshop
What is almost solved?
• Spatial/Temporal relations• Trajectory modeling/analysis/mining• Spatial/Temporal granularity• Event detection and conceptualization
3NSF GeoInformatics workshop
What has (failed)?
• Dealing with large amounts of data• Modeling complex spatiotemporal
behaviors• Deriving processes• Multi-scale approaches
not yet succeeded?
4NSF GeoInformatics workshop
What is missing?• Scalability• Spatiotemporal process
mining• “Making sense” of human
observations
