Multiple Representation and a Multidimensional Theory of Geographic Features and Relations

Developing high-level constructs for geographic data and feature representation that capture human cognition of geographic space and are efficiently implemented in computer systems is the objective of this project. The project is focused on multidimensional representation, including three-dimensional and temporal object attributes. The initial focus has been on watershed features for modeling and water-quality applications. A current focus is on feature extraction to support The National Map.
