2. HEM Overview Event Data Tools Application Integration What’s Next? Overview Geospatial 2007 Conference

3. What are the HEM Tools? ArcGIS tools for the creation, management, and refresh of event data that is referenced to stream data in the NHD format Developed by the Pacific Northwest Hydrography Framework Adapted from the Forest Service EventMaker Tools Geospatial 2007 Conference

4. HEM History • PNWHF Partners begin planning for an LLID to NHD transition. Event editing tools recognized as a need for partners. (Late 2005) • Requirements Gathering Phase (Late 2005 – Spring 2006) • Application Development Phase (June 2006 – April 2007) • Additional requirements accepted from NHD Partners (Oct 2006) • Tools released for User Acceptance Testing (March 2007) • First Release of Tools (April 2007) Geospatial 2007 Conference

6. What are Events? “Event tables contain information about assets, conditions, and events that can be located along route features. Each row in the event table references an event and its location is expressed as measurements along named linear features.” ESRI, ArcGIS Desktop Help Geospatial 2007 Conference

7. HEM Event Featureclasses Featureclasses with geometry Records contain route and measure attributes Linear events can span multiple routes (Multi-Route Linear Events) Traditional event tables can be generated from the HEM Event Featureclasses Geospatial 2007 Conference

8. Point Events Data Structure Geospatial 2007 Conference

9. Linear Events Data Structure – Single Route Events Geospatial 2007 Conference

10. Linear Events Data Structure – Multi Route Events * ID links to the “M” table

11. Linear Events Data Structure – Multi Route “M” Table * ID links to the event featureclass Geospatial 2007 Conference

22. Create Multiple Events Upstream • Set Edit Task • Set Edit Target • Activate HEM Sketch Tool • Click at a Point on a Stream • Events will be created from that point upstream

23. Create Multiple Events Downstream • Set Edit Task • Set Edit Target • Activate HEM Sketch Tool • Click at a Point on a Stream • Events will be created from that point downstream to the pour point

24. Measure Tools • Measure Linear Distance • Measures the distance along the flowline between two points. • Optionally converts results to a new linear event • Go X Distance • Displays a graphic a user defined distance up or downstream from a user defined point. • Optionally converts results to a new point event Geospatial 2007 Conference
