  1. Indiana State GIS Conference March 1, 2011 Indiana National Hydrography Dataset Improvement and Application Workshop

  2. Agenda Indiana’s NHD – Current Data Contents and Status Mike Martin, IDNR Improving the NHD Lacey Duncan (IDNR), Dave Nail (USGS), Terri McClean (AECOM), John Hendricks (AECOM) Q & A / Break Using NHD Applications Joanna Wood (IDEM), Mike Martin, Jeff Ehman (Image Matters) Stewardship of the NHD Dave Nail Q & A

  3. Agenda Indiana’s NHD – Current Data Contents and Status Mike Martin, IN Department of Natural Resources IGIC Waters Workgroup

  4. The Waters Framework Data Plan The Waters Framework Data Plan Highlights • Establishes the National Hydrography Dataset for Indiana as the IndianaMap framework data for surface water • Sets a strategy to correct errors and improve the NHD to Local Resolution • Identifies the State GIO as steward of the Dataset • Identifies a Data Maintenance Workflow

  5. Existing National Hydrography Dataset National Hydrography Dataset • Feature-based database of nation’s surface water drainage system, part of the National Map • Network of streams, rivers, and other flowlines; lakes, ponds, and other waterbodies • Other lines, areas, and points • Suitable for modeling water flow • Suitable for addressing local features and events to water features • Maintained at the state level and fed into national geodatabase

  6. Existing National Hydrography Dataset Existing condition of the NHD for Indiana • “High-resolution” NHD Features in current NHD based upon 20+ year-old paper1:24,000 (1” = 2,000’) USGS Topographic Quad Maps • Inconsistencies from quad to quad • Most users require data at better scale • Features have changed since maps were created • Problems with missing or incorrect names

  7. Stewardship of Indiana’s NHD Current Stewardship Workflow, owned by GIO • Download entire sub-basin (8-digit HUC) from USGS website • Edit, using NHD GeoEdit tools • Submit to USGS • Review by USGS • USGS loads into national database • Users need to re-download subbasin *Any names must be in GNIS names

  8. Improving Indiana’s NHD Benefits of NHD Upgrade to Local Resolution • Corrects the existence and the locations of physical features • Data would be at scale of 1:2,400 or 1:1,200 and aligned to 2005 IndianaMap Orthophotography • Inconsistencies between quads will be removed • Naming of features will be improved • Network connectivity and flow direction will be improved • Statewide water flow model of 2005 water features, ensuring connectivity and modeling across community boundaries • Statewide stream addressing system with linear referencing

  9. Improving Indiana’s NHD Improving the NHD will result in additional features added. Existing High-Res NHD in RED Improved NHD using 2005 DOQQ in BLUE

  10. Improving Indiana’s NHD Improving the NHD will result in alignment to 2005 IndianaMap Orthophotography Existing High Res NHD in RED Improved NHD YELLOW

  11. Improving Indiana’s NHD Strategy to Correct Errors and improve the NHD to local resolution • Correct GNIS name errors in High-Resoultion NHD • features missing names, incorrect names assigned to features, names missing from GNIS • workgroup members, IGIC intern • 21 subbasins complete • goal to finish in 2011 ……………………………more from Lacey coming up

  12. Improving Indiana’s NHD Strategy to Correct Errors and Upgrade the NHD • Correct GNIS name errors in High-Resolution NHD • Create local resolution NHD • Create features from 2005 IndianaMap Orthophotography and appropriate local vector data • Add correct attribute information for each feature, using existing NHD and other sources. • Create water flow direction and connectivity • AECOM/Pinnacle/Cripe

  13. Improving Indiana’s NHD Strategy to Correct Errors and Upgrade the NHD • Correct GNIS name errors in High-Resolution NHD • Create local resolution NHD • Create features from 2005 IndianaMap Orthophotography and appropriate local vector data • Add correct attribute information for each feature, using existing NHD and other sources. • Create water flow direction and connectivity • AECOM/Pinnacle/Cripe • pilot study Eel River subbasin, 2nd quarter 2011 • Funded by USGS

  14. Improving Indiana’s NHD Strategy to Correct Errors and Upgrade the NHD • Correct GNIS name errors in High-Resolution NHD • Create local resolution NHD • Create features from 2005 IndianaMap Orthophotography and appropriate local vector data • Add correct attribute information for each feature, using existing NHD and other sources. • Create water flow direction and connectivity • AECOM/Pinnacle/Cripe • Phase 2, 2nd half 2011(?) • Funded by Office of Community and Rural Affairs, Disaster Recovery Funds

  15. Improving Indiana’s NHD Strategy to Correct Errors and Upgrade the NHD • Correct GNIS name errors in High-Resolution NHD • Create local resolution NHD • Create features from 2005 IndianaMap Orthophotography and appropriate local vector data • Add correct attribute information for each feature, using existing NHD and other sources. • Create water flow direction and connectivity • AECOM/Pinnacle/Cripe • remainder of state as funds become available

  16. Improving Indiana’s NHD Strategy to Correct Errors and Upgrade the NHD • Correct GNIS name errors in High-Resolution NHD • Create local resolution NHD • Create features from 2005 IndianaMap Orthophotography and appropriate local vector data • Add correct attribute information for each feature, using existing NHD and other sources. • Create water flow direction and connectivity • AECOM/Pinnacle/Cripe ……………………………more from Terri and John coming up

  17. Improving Indiana’s NHD Strategy to Correct Errors and Upgrade the NHD • Correct GNIS name errors in High-Resolution NHD • Create local resolution NHD • Load local resolution into national database • Flowlines and waterbodies loaded into IndianaMap

  18. Future Maintenance Future Stewardship Workflow • Provide tools for sub-stewards to easily submit attribute corrections • Names • Classifications, e.g. perennial, intermittent • Geosynchronization to allow users to subscribe to areas, be notified of changes, and get feature-based updates. ….……………………….more from Kurt coming up
