Indiana’s NHD – Current Data Contents and
Status

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

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

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

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

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

Improving Indiana’s NHD
Improving the NHD will
result in additional features
added.

Improving Indiana’s NHD
Strategy to Correct Errors and improve the NHD to
local resolution
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

Improving Indiana’s NHD
Strategy to Correct Errors and Upgrade the NHD
1. Correct GNIS name errors in High-Resolution NHD
2. 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

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.
