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

hydrologic information system

Analysis, Modeling,

Decision Making

Arc Hydro

Geodatabase

Hydrologic information system

A Synthesis of geospatial and temporal information that a which supports hydrologic analysis and modeling

arcgis features
ArcGIS features

GIS uses features and tables to describe a simplification of a “system” in this case the hydrological description.

3D features: 3D points, 3D lines and 3D polygons

2D features: Points, lines and polygons

Points - Wells

Polygons - Aquifers

3D points

Lines-

River network

3D lines -Wells

key points
Key points
  • Arc Hydro is a geographic data model – basis for hydrological information system
  • Extended to include the main features of groundwatersystems
  • Provide a data interface between ArcGIS and commonly used groundwater modeling programs
  • Integration of models through the data model.
