Abstract
Building a Geodatabase for Watershed Management
Track: Database Design, Automation, and Management
Author(s): Mark Joselyn
Object-oriented data models have significantly altered how geographies are represented in a GIS. The geometry of a feature is carried as an attribute. Spatial relationships are not imbedded within the underlying data structure. This new, more abstract data model has benefits for built environments. Leveraging object-oriented data models in the context of natural environments presents real challenges. This presentation will explore these issues in the context of the City of Seattle's Cedar River Municipal Watershed, a 91,000-acre ecological reserve that provides drinking water for more than 1.2 million people in the Puget Sound region. Strategies for transitioning to object-oriented database technology and modeling the natural environment will be discussed.
