1 Indiana GIS Local Resolution NHD Applications Indiana State GIS Conference May 7, 2013

2 Agenda Topics I. Indiana s National Hydrography y Data II. Accessing NHD Data III. Demonstrations Using Local NHD Data IV. Stewardship of Indiana s NHD Presenters, Waters Workgroup Members Mike Martin, Indiana Dept. of Natural Resources David Nail, United States Geological Survey Dave Knipe, Indiana Dept. of Natural Resources

3 Indiana s Existing Statewide Hydrography Data Contents and Status Part I

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

5 National Hydrography Dataset Surface water component of the National Map

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

7 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 National Hydrography Dataset

8 National Hydrography Dataset Enables the modeling of water flow in GIS applications National Hydrography Dataset

9 National Hydrography Dataset Indiana data stewardship is responsibility of State GIO partnership with IGIC National Hydrography Dataset

10 Project to Improve Indiana s NHD Correct & Upgrade NHD to Local Resolution Correct the existence and the locations of physical features using 2005 and newer Orthophotography and LiDAR Align features to the orthophotography, good at scale of 1:2,400 or 1:1, Remove inconsistencies between USGS quadrangles Improve naming of features Improve etwork connectivity and flow direction 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

11 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

12 Results: Improved Alignment High Res / RED Local / YELLOW

44 Part III Software Demonstrations Using Local- Resolution NHD Dave Knipe, IDNR

45 Using Utility Network Analyst with NHD NHD geodatabase network topology allows for analyzing waterflow Utility Network Analyst is Tool in ESRI ArcMap ArcView (Basic) license, no extension required Requires NHD geodatabase hydrography dataset, not just feature classes/vector graphics Hydro_Net_Junctions NHDFlowline

46 Analyzing Water Flow with NHD Tools in the Utility Network Analyst Toolbar Show Flow Direction Determine common ancestors Find connected flowlines Trace downstream or upstream Find path upstream or downstream Find upstream accumulation Results can be saved as a feature class

47 Using Utility Network Analyst with NHD Add data from the NHD geodatabase to the Map Hydrography dataset HYDRO_NET HYDRO_NET_Junctions NHDFlowline Add Other data as needed (not required)

48 Using Utility Network Analyst with NHD

49 Turn on the Utility Network Analyst Toolbar in ArcMap Set Network to HYDRO_ NET Using Utility Network Analyst with NHD

50 Using Utility Network Analyst with NHD Show Flow Direction From Flow menu, select Display Arrows High Resolution Local Resolution

56 Part IV NHD Stewardship and Maintenance

57 National Hydrography Dataset Indiana data stewardship is responsibility of State GIO partnership with IGIC Continued Stewardship

58 Continued Stewardship Maintenance after the Upgrade Critical to providing a statewide dataset that can be beneficial to users across the state at all levels Names of features Classifications of features Presence or location of features Help wanted

59 Workflow of Future Maintenance Continued Stewardship

60 Continued Stewardship Proposing Names for Un-Named Features All names in NHD must first be in the national Geographic Names Information System, GNIS 1. Local reviewer proposes a new name 2. Local Name Authority is notified of submitted name and reviews the request/proposal. 3. Indiana NHD reviews approved local submission. 4. The Indiana BGN meets to review and approve or reject the new name. If the name is rejected, the Actors in steps #1 - #3 are notified of the decision. 5. If approved, the Indiana BGN, or other party, submits the proposed name change to the US BGN.

61 Continued Stewardship Web Application to Submit Names

62 Continued Stewardship For more information: 4:00 Today, Prairie Creek Room Project to Enable Locals to Propose New Names for Local-Resolution NHD Streams and Water Bodies in Indiana
