This project originated from a need by GIS technical staff at the Washington State Department of Natural Resources’ (DNR) Information Technologies Division. The DNR has begun converting their statewide hydrographic data to a data model called the Framework Model. It is based on the Environmental Systems Research Institute (ESRI) coverage model of routes and events. More recently, ESRI has released new editing and analysis tools in ArcGIS 8.3 for routes and events using their geodatabase technology. ESRI has also recently publicized the release of a new hydrographic data model called Arc Hydro. Arc Hydro also utilizes the latest ESRI geodatabase technology while modeling rivers, streams, water bodies and watersheds as connected networked features.

With the DNR moving towards conversion to the Framework data model, while developing new tools to maintain the data, they needed to know what the latest technology in ArcGIS 8.3 had to offer. They were also intrigued by Arc Hydro and how it can be applied using their data.

This project implemented editing and analysis techniques using ArcGIS 8.3. While written largely in the style of a software tutorial, it differs from ESRI’s generic tutorial in that it makes specific use of the DNR’s hydrography data and demonstrates a seamless process of data maintenance and editing while meeting the Framework data model requirements. It also steps through the process of building an Arc Hydro geodatabase and provides insight into some analysis possibilities.
