  1. USGS Perspective on The Ele-Hydro Concept Adapted from a presentation by Jeff Simley USGS National Hydrography Data Manager

  2. Erosion and Resistance

  3. Integration and registration

  4. Heads-up Digitizing Contours integrated with Hydro http://letters-sal.blogspot.com/2011/05/digitizing-wacom-way.html

  5. How we think and collect now. . . Separate funding mechanisms $$$ Indiana LiDAR $3.3million Indiana Hydro $2.6million Managed separately Hydro Elevation Stovepiped Empires Turfs • National Hydro Data • 100k • 24k • Local Data • Watersheds • Vector National Elevation Data PointCloud DEM Raster Separate data standards Data housed separately (raster vsvector) Separate collection methods

  6. High Resolution lidar DEM

  7. Indiana’s National Hydrography Data Update Project Illinois - Indiana

  8. Hydro Drainage features Wetlands DEM Hydro-Flatten Hydro-Enforced Watershed Boundaries LiDAR Point Cloud Catchments Subbasins Floodplains Infra- structure Building footprints Utilities Roof analysis Transportation signage Veg Forest Canopy Forest Health Crop Health Grasslands Soils

  9. How we think now - Some integration occurring. . . Hydro USGS Apps: StreamStats NHDPlus U.S. Topo Combined Elevation Forcing integration by “burning” the Hydro data into the Elevation data

  10. U.S. Topo

  11. Packaging the Data NHD Wetlands Catchments Landcover Vegetation Elevation

  12. Derive hydrography from the terrain

  13. Indiana’s Local-Resolution NHD streams and lidar DEM

  14. Integration – What does it mean? Alignmentof elevation and hydrography such that streams flow in channels Interoperabilitysuch that a levee can be connected to a river Data Modelthat links elements and features Synthesissuch that streamflow can be estimated Derivativessuch that gradient, channel dimensions, etc. can be calculated Programwhere a DEM and Hydro can be jointly produced and funded Synchronizationso that data are temporally coincident Productin a way that both elevation and hydro can be packaged together Deliveryof data to be accessed in unison

  15. Integration – Why? Reduce cost Provide improved credibility Produce accurate data Increase the value of the data Empower science-based decisions Challenge and drive research

  16. An Integrated Landscape “All geospatial software is moving to 3D. It is now an expectation.” Steve Snow, ESRI Imagingnotes.com, http://www.imagingnotes.com/go/article_freeJ.php?mp_id=292
