Agenda

Indiana’s NHD – Current Data Contents and Status

Mike Martin, IN Department of Natural Resources

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
