Indiana GIS Local Resolution NHD Applications for Surveyors

1. ISPLS State Conference January 18, 2013 (12:45 pm – 3:30 pm) Indiana GIS Local Resolution NHD Applications for Surveyors

2. Agenda Topics Indiana’s National Hydrography Data Accessing NHD Data Software Demonstrations Uses of NHD Data Future Applications Using NHD Stewardship of Indiana’s NHD Presenters Mike Martin, Indiana Dept. of Natural Resources David Nail, United States Geological Survey Dave Knipe, Indiana Dept. of Natural Resources Phil Worrall, Indiana Geographic Information Council

3. Agenda Indiana’s Existing Statewide Hydrography Data –Contents and Status

4. IGIC and the Waters Workgroup IGIC’s - Waters Framework Dataset Workgroup Mission: To develop plans, standards, and technical implementation guidance for the IndianaMap hydrography framework data layers.

5. Advantages of Statewide Framework Data Statewide framework data allow for use at the local, regional, and state levels with no consistency problems sometimes associated with using data from multiple sources. • edgematching, differently catagorized features, different scales, etc. • enables modeling (waterflow) across political boundaries Enables users throughout the state to use the SAME data, regardless of application extent.

6. Surface Waters Framework Dataset IGIC’s - Waters Framework Dataset Workgroup Established National Hydrography Dataset (NHD) as the statewide framework dataset for surface waters

7. National Hydrography Dataset National Hydrography Dataset • Surface water component of the National Map

8. National Hydrography Dataset National Hydrography Dataset • Vector data for mapping and modeling • watersheds • streams, rivers, canals, ditches • lakes, ponds, reservoirs, marshes • streamgages • other features

9. National Hydrography Dataset National Hydrography Dataset • Can be used in GIS for general mapping and analysis of surface-water systems • Can be used in CAD as planimetric basemap data

10. National Hydrography Dataset National Hydrography Dataset • Enables the modeling of water flow in GIS applications

11. National Hydrography Dataset National Hydrography Dataset • Indiana data stewardship is responsibility of State GIO • partnership with IGIC

12. Project to Improve Indiana’s NHD Correct & Upgrade NHD to Local Resolution • Use 2005 and newer Orthophotography and LiDAR to correct 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 or better • Inconsistencies between USGS quadrangles will be removed • Naming of features will be improved • Network connectivity and flow direction will be improved • Result in statewide water flow model of 2005 or later water features, ensuring connectivity and modeling across community boundaries • Statewide stream addressing system with linear referencing

13. Improving Indiana’s NHD Strategy to Correct Errors and Upgrade the NHD • Correct GNIS name errors in High-Resolution NHD (2011) • Create local resolution NHD • Load local resolution data into the national database, includes network topology for modeling • Load flowlines and waterbodies datasets into the IndianaMap for use and download

14. NHD Upgrade Project Status Phase 1, 30 Subbasins • Currently underway • Funded by Office of Community and Rural Affairs, Disaster Recovery Funds • Goal for completion of Phase 1 is Dec 2013

15. Results: Increase in Number of Features High-Res in RED Local Res in BLUE 49% increase in acres of waterbodies 134% increase in acres of areas 409% increase in miles of flowlines

16. Results: Improved Alignment High Res / RED Local / YELLOW

17. Continued Stewardship Maintenance after the Upgrade • Critical to providing a statewide dataset that can be beneficial to users across the state at all levels • Identify individuals and organizations that can help as sub-stewards for their areas of interest • Provide tools for sub-stewards to easily submit corrections • Names of features...may require new names in GNIS • Classifications, e.g. perennial, intermittent, ditch, etc. • Presence or locations of features ….……………………….more from Phil later
