2 May 9, 2007Geospatial 2007 Conference HEM Overview Event Data Tools Application Integration Whats Next? Overview

3 May 9, 2007Geospatial 2007 Conference 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

4 May 9, 2007Geospatial 2007 Conference 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) HEM History

6 May 9, 2007Geospatial 2007 Conference 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

7 May 9, 2007Geospatial 2007 Conference 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

14 May 9, 2007Geospatial 2007 Conference Managing Data - ArcCatalog Tools Editing Data - ArcMap Tools The Tools

15 May 9, 2007Geospatial 2007 Conference { { Event featureclasses in the selected geodatabase Interface for creating new event featureclasses ArcCatalog: Event Table Manager

16 May 9, 2007Geospatial 2007 Conference Selection Tool Sketch Tool Edit Tasks Edit Targets Edit Tools ArcMap: HEM Toolbar

17 May 9, 2007Geospatial 2007 Conference 1.Activate HEM Sketch Tool 2.Set Edit Task – Create Point – Create Line 3.Set Edit Target 4.Click on stream to define endpoint(s) Click for downstream point, then shift + click for upstream point Create Events

18 May 9, 2007Geospatial 2007 Conference Mouse Information Current route location displayed in the lower left- hand corner of the ArcMap window

19 May 9, 2007Geospatial 2007 Conference 1.Set Edit Task – Update Point – Update Line 2.Activate Select Event Tool 3.Select Event to Update 4.Define new endpoint(s) Click for downstream point, then shift + click for upstream point Update Events

20 May 9, 2007Geospatial 2007 Conference 1.Set Edit Task 2.Set Edit Target 3.Activate Select Event Tool 4.Select an Existing Event 5.Event record is copied Copy Events Identify results after an existing record is copied.

21 1.Set Edit Task 2.Activate Select Event Tool 3.Select an Existing Event 4.Selected event record is deleted Delete Events

22 1.Set Edit Task 2.Set Edit Target 3.Activate HEM Sketch Tool 4.Click at a Point on a Stream 5.Events will be created from that point upstream Create Multiple Events Upstream

23 1.Set Edit Task 2.Set Edit Target 3.Activate HEM Sketch Tool 4.Click at a Point on a Stream 5.Events will be created from that point downstream to the pour point Create Multiple Events Downstream

24 May 9, 2007Geospatial 2007 Conference 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 Measure Tools

25 Synchronize Events Can be run on one or more event featureclasses Works off of the selected set of records Compares ReachSMDate Opens a user interface to facilitate update Update: Auto-Match or Manual Edit

26 May 9, 2007Geospatial 2007 Conference Check Continuous Events Checks events for gaps and overlaps between records Provides an output report

27 May 9, 2007Geospatial 2007 Conference Clear HEM Elements Snap Environment Select by Selected Import Points Additional Edit Tools
