The waters workgroup

The Waters Workgroup

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

  • Made up of members who are able to participate in meetings in person or via phone and members who follow the activities and review documents via the ListServ.

  • Scheduled meetings 1st Wednesday/month, in Indianapolis, with phone-in option.

  • Currently, active members represent mostly state and federal agencies and IGIC.

  • Members of the Waters ListServ include the above and also representativies of local agencies, universities, and private entities.

Topics

  • The Waters Workgroup

  • <= 2009: Waters Data Plan


2009 the waters data plan

<= 2009: The Waters Data Plan

The Waters Data Plan Highlights

  • Establish the National Hydrography Dataset for Indiana as the IndianaMap framework data

  • Strategy to correct errors and improve the NHD to Local Resolution

  • Stewardship of the Dataset

  • Data Maintenance Workflow


The waters data plan existing data

The Waters Data Plan—existing data

National Hydrography Dataset

  • Feature-based database of nation’s surface water drainage system

  • Network of streams, rivers, and other flowlines; lakes, ponds, and other waterbodies

  • Other lines, areas, and points

  • Suitable for modeling water flow

  • Suitable for geocoding local features and events to water features

The waters data plan existing data1

The Waters Data Plan—existing data

Existing condition of the NHD for Indiana

  • “High-resolution” NHD Features in current NHD based upon 20+ year-old paper 1:24,000 (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


2009 the waters data plan1

<= 2009: The Waters Data Plan

The Waters Data Plan Highlights

  • Establish the National Hydrography Dataset for Indiana as the IndianaMap framework data

  • Strategy to correct errors and improve the NHD to Local Resolution


The waters data plan strategy

The Waters Data Plan—Strategy

Strategy: Correct errors and improve the NHD to local resolution.

To be done by subbasin as funds allow.

  • Correct GNIS name errors in High-Resoultion NHD

  • Create features from 2005 IndianaMap Orthophotography and appropriate local vector data

  • Assign correct NHD feature code to each feature.

  • Edgematch features to best available NHD data in adjacent subbasin

  • Create water flow direction and connectivity

  • Conflate to those features the NHD attributes from High-Res


The waters data plan strategy1

The Waters Data Plan—Strategy

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 1:2,400 layers of 2005 streams and lakes/ponds.

  • Statewide water flow model, ensuring connectivity and modeling across community boundaries

  • Statewide stream addressing system with linear referencing

Improving the NHD will result in additional features added.

2009 the waters data plan2

<= 2009: The Waters Data Plan

The Waters Data Plan Highlights

  • Establish the National Hydrography Dataset for Indiana as the IndianaMap framework data

  • Strategy to improve the NHD to Local Resolution

  • Stewardship of the dataset


The waters data plan stewardship

The Waters Data Plan—Stewardship

Indiana State Geographic Information Officer to serve as official Steward

  • Partnership with the US Geological Survey

  • Coordinate all NHD maintenance activities for Indiana

    • assisted by other agencies and organizations as secondary stewards


Waters data plan stewardship duties

Point of contact for the USGS

Represent the interests of the user community

Accept updates from other agencies and organizations

Respond to proposed updates within an agreed-upon, reasonable time

Maintain an awareness of the activities of other agencies and organizations involved

Provide contact information for management and technical issues

Provide publicly available information on the status of data stewardship activities

Perform activities defined in the IndianaMap NHD Local Resolution Update and Maintenance Workflow as funding allows.

Provide metadata that clearly describe the sources used in updates and the process

Utilize nationally consistent reach codes

Seek funding to support the activities

Agree to and adhere to the Quality Control Specifications

Actively seek agencies and organizations interested in acting as secondary stewards
