Agenda
Indiana’s NHD – Current Data Contents and Status

IGIC Waters Workgroup
Coordination of Indiana GIS through dissemination of data and data products, education and outreach, adoption of standards, and building partnerships
The Waters Framework Data Plan
• 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
The Waters Framework Data Plan Highlights
Coordination of Indiana GIS through dissemination of data and data products, education and outreach, adoption of standards, and building partnerships
Existing 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

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
Coordination of Indiana GIS through dissemination of data and data products, education and outreach, adoption of standards, and building partnerships
Stewardship of Indiana’s NHD
• 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
Current Stewardship Workflow, owned by GIO
Coordination of Indiana GIS through dissemination of data and data products, education and outreach, adoption of standards, and building partnerships
Improving Indiana’s NHD
• 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
Benefits of NHD Upgrade to Local Resolution

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

Improving Indiana’s NHD
1. 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
Strategy to Correct Errors and improve the NHD to local resolution
Coordination of Indiana GIS through dissemination of data and data products, education and outreach, adoption of standards, and building partnerships
Improving Indiana’s NHD
1. Correct GNIS name errors in High-Resolution NHD2. 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

Future Maintenance
• 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
