IGIC and the Waters WorkgroupIGIC’s - Waters Framework Dataset Workgroup

Mission: To develop plans, standards, and technical implementation guidance for the IndianaMap hydrography framework data layers.

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 boundariesEnables users throughout the state to use

the SAME data, regardless of application extent.

Surface Waters Framework Dataset

IGIC’s - Waters Framework Dataset WorkgroupEstablished National Hydrography Dataset (NHD) as the statewide framework dataset for surface waters

National Hydrography Dataset

• Surface water component of the National Map

National Hydrography Dataset

National Hydrography Dataset

• Vector data for mapping and modeling • watersheds• streams, rivers, canals,

ditches • lakes, ponds, reservoirs,

marshes • streamgages• other features

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

Project to Improve Indiana’s NHD

• 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

Correct & Upgrade 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 NHD (2011)

2. Create local resolution NHD 3. Load local resolution data into the

national database, includes network topology for modeling

4. Load flowlines and waterbodies datasets into the IndianaMap for use and download

Strategy to Correct Errors and Upgrade the NHD

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

Results: Increase in Number of FeaturesHigh-Res in REDLocal Res in BLUE49% increase in acres of waterbodies

134% increase in acres of areas

409% increase in miles of flowlines

Continued Stewardship

• 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 correctionso Names of features...may require new names in

GNISo Classifications, e.g. perennial, intermittent, ditch,

etc.o Presence or locations of features….……………………….more from Phil later
