• Bringing together these two communities by using a common geospatial data model
• Arc Hydro design took 3 years from 1999 – 2002. Groundwater phase II 2002 - 2005.

Geographic Data Model
• Conceptual Model – a set of concepts that describe a subject and allow reasoning about it
• Mathematical Model – a conceptual model expressed in equations
• Data Model – a conceptual model expressed in a data structure
• Geographic Data Model – a data model for describing and reasoning about the world
A model is a simplification of reality
