Waters Framework Dataset Workgroup Update

Waters Framework DatasetWorkgroup Update

Indiana State GIS Conference

February 23, 2010

Coordination of Indiana GIS through dissemination of data and data products, education and outreach, adoption of standards, and building partnerships

Topics

• The Waters Workgroup• <= 2009: Waters Data Plan• 2009: Project Grants• 2010


The Waters Workgroup

• 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.

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

Topics

• The Waters Workgroup• <= 2009: Waters Data Plan


<= 2009: The Waters Data Plan

• 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 Highlights


The Waters Data Plan—existing data

• 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 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




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



The Waters Data Plan—Strategy

• 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

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

To be done by subbasin as funds allow.



• 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

Benefits of NHD Upgrade to Local Resolution



Existing High-Res NHD in RED

Improved NHD using 2005 DOQQ in BLUE

Improving the NHD will result in additional features added.



Improving the NHD will result in alignment to 2005 IndianaMap Orthophotography

• Strategy to improve the NHD to Local Resolution

• Stewardship of the dataset



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

1. Point of contact for the USGS2. Represent the interests of the

user community 3. Accept updates from other

agencies and organizations4. Respond to proposed updates

within an agreed-upon, reasonable time

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

6. Provide contact information for management and technical issues

7. Provide publicly available information on the status of data stewardship activities

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

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

10. Utilize nationally consistent reach codes

11. Seek funding to support the activities

12. Agree to and adhere to the Quality Control Specifications

13. Actively seek agencies and organizations interested in acting as secondary stewards




• Strategy to improve the NHD to Local Resolution

• Stewardship of the dataset• Data Maintenance Workflow



The Waters Data Plan—Maintenance

Maintenance after sub-basin has been upgraded


Topics

• The Waters Workgroup• <= 2009: Waters Data Plan• 2009 Project Grants


2009 Project Grants

GNIS Corrections for High-resolution NHD

• $25,000 Grant from US Geological Survey

• Critical step prior to upgrading NHD to local resolution

• Correct names in GNIS• Match GNIS names to NHD Features• Add missing names, fix bad names• Submit changes to USGS


2009 Project Grants

IN Dept. of Environmental Management

• $200,000• 8 sub-basins within the

GLI

Development of Local Resolution NHD for the Great Lakes Initiative Area of Indiana

US Geological Survey• $29,000• 1 sub-basin within the

GLI

PHASE 1 OF LOCAL RESOULTION IMPROVEMENT PROJECT


Topics

• The Waters Workgroup• <= 2009: Waters Data Plan• 2009 Project Grants• 2010


Waters Workgroup 2010

1. Complete GNIS Hydrographic Name Corrections Project
