Thirteen subbasins are currently in production for the local resolution NHD. USGS is still working out the kinks to upload the Upper Eel data. Once they are successful with that, Middle Wabash-Deer, Wildcat, and Iroquois should soon follow.

There are nine other subbasins are in various stages of production. Workgroup members Dave Nail, Phil Worrall, Lacey Duncan, and Joanna Wood have been QCing linework after they are reviewed by AECOM.

June 21, 2012

Lots of activity to report for this period. The Waters Workgroup, GIO, AECOM, and USGS continue working together on the NHD Upgrade project. The production process is stabilizing and increasing, but because of the quality of everyone’s efforts, the team has been able to cut back from weekly meetings to holding meetings every other week.

The Upper Eel Pilot subbasin has been successfully upgraded and USGS is waiting on a new tool before loading it into the national geodatabase. The Iroquois, Middle Wabash-Deer and Wildcat subbasins have gone through QC and will soon go through the final conversion steps before submitting to USGS. The Upper East Fork White, Flatrock-Haw, Driftwood, Muscatatuck, and Lower East Fork White subbasins are in various stages of conversion.


April 19, 2012

Progress on Local Resolution NHD Project: Workgroup members have performed QC on three subbasins (Upper Eel, Iroquois, and Wildcat) submitted by AECOM. USGS and AECOM are working to finalize uploading the upgraded Upper Eel geodatabase to the national geodatabase. Once subbasins are completed and available for distribution, it will be important to get feedback from local experts on needed changes to attributes, particularly feature names and whether features are perennial, intermittent, or ephemeral.

NHD Stewardship Conference: Dave Nail, Joel Skalet, and Mike Martin participated in the NHD Stewardship Conference held in New Orleans in March. Mike presented an update on our local resolution project.


February 16, 2012

The Workgroup has developed a set of goals for the upcoming year:

  • Oversee completion of Phases 1 and 2 of the local resolution improvement project
  • Work with IGIC for inventory of local data availability and incorporate into data plan
  • Assist State GIO with identification and pursuit of funding opportunities
  • Assist State GIO with identification and training of sub-stewards for maintenance
  • Sponsor “Using the NHD” workshop
  • Find opportunities to work with other states and federal agencies to advance our mission
  • Develop and maintain the Indiana Map data integration section for the waters framework data

December 8, 2011

AECOM has begun work on the local resolution NHD upgrade. The workgroup has had many teleconferences with AECOM over the past quarter. The priority schedule below is by subbasin, was established based upon needs and the ongoing state Imagery/LiDAR acquisition schedule. AECOM has submitted its line work for the Upper Eel Watershed, which is now under QC Review. As work on each subbasin is completed, including all reviews, the subbasin will be submitted to USGS to replace the high resolution (1:24,000) NHD for that subbasin.

October 20, 2011

At long last, work has begun on the Pilot Project for the NHD Local Resolution Upgrade project. The contract between the GIO and AECOM has been signed and the workgroup held a kickoff meeting with AECOM on October 5th. The target date for completion of the Upper Eel subbasin is February 20, 2012. The Workgroup has scheduled weekly conference calls and will be working closely with AECOM throughout the pilot phase.

April 28, 2011

The Waters Workgroup, specifically Dave Nail, Joanna Wood, Cindy Martin, and Lacey Duncan, continue to work on making corrections to the GNIS for surface water features. These corrections are a critical first step to the NHD Local Resolution project. Thirteen subbasins remain to be corrected and submitted to USGS.

The Local Resolution Upgrade project ran into funding issues regarding an EPA grant to IDEM. Those funds were to be used for Phase 1, the Great Lakes Initiative Area. As a result, the contract work between IOT and AECOM needed to be redone. The current agreement is being finalized for the Pilot Project (Eel River Subbasin), and what was previously designated as Phase 2, the remaining non-Great Lakes Initiative Area subbasins. The Phase 2 subbasins are being funded through a grant from the Office of Community and Rural Affairs (OCRA). It is hoped that the contract will be signed and work will begin within the next month.

Jeff Ehman (Image Matters) demonstrated the Geo-synchronization Tool for the NHD to the Workgroup at its April meeting. The tool should prove to greatly improve the efficiencies of approving and distributing approved edits to NHD data.

February 28, 2011

The Waters Workgroup is in somewhat of a “hurry up and wait” mode. The most significant accomplishment for 2010 was to assist workgroup member and State Geographic Information Officer Jim Sparks in the selection of a vendor for the Local Resolution NHD project. AECOM, working with Cripe Architects and Engineers and Pinnacle Mapping Technologies as subcontractors, was awarded the rights to negotiate a contract to upgrade the NHD to local-resolution, as funds are available. The Upper Eel Subbasin is scheduled to be the pilot project area. The remaining 8 subbasins in the Great Lakes Initiative Region were to be Phase 1. However, obstacles in coordinating the IDEM/EPA funding, project timelines, and other factors have put Phase 1 in hiatus. Efforts are currently underway to get paperwork signed to begin the Pilot Project, being funded through a grant from USGS. Meanwhile, AECOM has been provided the datasets that they need to begin the work.

Several members of the Workgroup have been working diligently on checking and correcting errors in the existing NHD feature names. The feature names come from the GNIS (Geographic Names Information System). There are many cases of features not being named, features named incorrectly, and some cases of the correct name not existing within the GNIS. All of these errors must be corrected prior to the NHD upgrade to local resolution. Of the 38 subbasins in Indiana, 21 have been corrected; Dave Nail is currently coordinating this effort.

The USGS provided a 3-day training session for workgroup members, AECOM, and its subcontractors on the conflation process and QA/QC.

Outreach presentations were given by workgroup members at the Indiana Association for Floodplain and Stormwater Management annual conference, Indiana state agency GIS User Group Meeting, and IGIC annual conference.
The USGS/IGIC/Image Matters geo-synchronization tool currently being developed will provide the ability to update individual or small groups of NHD features with corrected names, geometry, or other attribute information. This will significantly improve the efficiency of making such updates.

December 3, 2010

The Waters Workgroup is awaiting the finalization of NHD Local-Resolution contracts between the state and AECOM and IGIC. Phil Worrall has worked with Jim Sparks to develop the pre-conversion, conversion, and post-conversion tasks. The pre-conversion tasks have been completed for the Upper Eel pilot project area. The November and December workgroup meetings were cancelled since the contracts had not yet been signed.

Regarding other projects, the GNIS Names corrections for water features is progressing. Although the grant money has been depleted, workgroup members are assisting with this effort as they can. Development of the NHD Geo-Synchronization tools is underway by Image Matters. A beta release for the workgroup to begin testing is expected before the end of this year.

October 21, 2010

The Waters Workgroup continues to prepare for the NHD Upgrade project.

GNIS Names Project: Several members of the Workgroup have been updating the GNIS (Geographic Names Information System) data for NHD water bodies and flow lines. To date, 15 sub-basins have been completed and submitted to USGS, 3 more are completed and under final review, 5 are in production, and 15 remain to be started. Many thanks go to Dave Nail for coordinating this with Phil Worrall.

Local-Resolution NHD: USGS’s Elizabeth McCartney provided three days of NHD Conflation training to members of what will become IGIC’s project production and QA/QC support team. The 2005 digital orthophotography, DEM and several other reference datasets have been provided to AECOM in anticipation of the contract being signed soon.

Workgroup member Lacey Duncan presented an ‘NHD Upgrade Project’ update to the Indiana Association for Floodplain and Storm Water Management Conference, and will also give the presentation at the GIS Day at the State meeting on November 9th.

August 19, 2010

In preparation for upgrading Indiana’s National Hydrography Dataset to local resolution, former IGIC Intern Geoff Hibbert and members of the Workgroup have been working to correct errors in the GNIS names as they relate to the high-resolution NHD. Of the 38 sub-basins, 13 have been submitted to USGS, and 6 others are currently being corrected. The Waters Workgroup participated in a kickoff meeting with AECOM for the NHD upgrade contract. Once the contract signatures are in place, AECOM and its subcontractors will begin work on the Upper Eel sub-basin. Reference datasets, including orthophotography (thanks to Anna Radue) have been delivered to AECOM. Later this month, several members of the workgroup will be participating in a USGS workshop on NHD conflation.

June 17, 2010

The Waters Workgroup has been very active working on GNIS Updates to Indiana’s High-resolution NHD, as well as working with the State GIO on the NHD Local-Resolution RFP and vendor selection process. Our last meeting was held on June 2nd with the GIO’s office and served as the NHD Local-Resolution project kickoff meeting with the selected vendor AECOM.

April 15, 2010

The Waters Workgroup met in early March and teleconferenced in late March. One subcommittee reviewed the RFP proposals and provided recommendations to the Department of Administration (IDOA). IDOA then added scoring based upon Buy Indiana, and Minority and Women-owned Businesses factors. They (IDOA) have not finalized the selection. Meanwhile, a second workgroup subcommittee has been working to correct the Geographical Names Information System (GNIS) names for streams, rivers, lakes, ponds, and reservoirs in the high-resolution National Hydrography Dataset (NHD). These changes are necessary prior to beginning the NHD Improvement process. Phil Worrall and Dave Nail have combined efforts to submit grant proposals to USGS for extending the NHD Improvement project beyond the Great Lakes Initiative Area. One proposal has been deferred and a second is under review.

February 22, 2010

The request for proposal (RFP) for the NHD local resolution project selection had been completed. There were four proposals presented. The selection is now waiting for approval and should be finalized at the end of February. The target for having and starting the project is March.

December 3, 2009

The Waters Workgroup is excited to report that the Local Resolution NHD RFP will be posted very soon. The tentative timeline is as follows:

RFP Notice Date: November 30, 2009
Deadline for Questions Date: December 11, 2009 – 3:30 pm
Question Responses Published Date: December 18, 2009
Deadline for Receipt of Proposals Date: December 30, 2009 – 3:30 pm
Notification of Award Date: January 15, 2010
Contract Start Date: February 1, 2010

The NHD Stewardship MOU has been forwarded to USGS for signature. Jim Sparks will be the state signatory and he will be looking for sub-stewards. The GNIS update project has begun with IGIC hiring an intern to assist. The goal is to complete at least the Phase 1 local-resolution sub-basins by February, as they will be needed for the NHD upgrade. A few members of the Workgroup will assist with the work once the update process is firmly established.

October 15, 2009

The Waters Workgroup is working to finalize two major documents: Phil Worrall is finalizing an RFP for work to improve the NHD to local resolution, and Jim Sparks is finishing a Stewardship Agreement with the USGS. Several members of the workgroup participated in a one-day workshop with USGS’s Elizabeth McCartney. The workshop focused on updating the geographic names, updating the NHD, and conflation. The Waters Data Plan draft has been updated and will be available on the workgroup’s website.

August 20, 2009

The Waters Workgroup is working toward finalizing language for two major documents: the MOU with the US Geological Survey (USGS) for stewardship of the National Hydrography Dataset (NHD) for Indiana, and the Request for Proposal for upgrading the NHD to local resolution. A $25,000 grant from USGS to update the Geographic Names included within NHD has been signed by IGIC and sent to USGS for their signature. The $29,000 grant from USGS for the Upper Eel Watershed NHD upgrade has also been signed and sent back to USGS.

June 18, 2009

The Workgroup met on May 6th to finalize the workflow and MOU. David Nail presented a USGS National Hydrography Dataset (NHD) video and demonstrated NHD edit tools.

A Request for Proposal document is being prepared for the Great Lakes NHD Updates, and the consensus is to create a Request for Proposal for the entire state, with work orders prepared for priority areas as money becomes available. It was also suggested that a vendor be required to be certified by US Geological Survey for updating NHD.

Next Steps

  • Complete RFP for vendor bid process
  • Stewardship MOU – Jim Sparks, GIO to sign
  • Local data availability survey – Phil Worrall, Jim Sparks to follow up

April 16, 2009

A draft of the workflow, data update/maintenance, and recommendations for data stewards has been developed. These draft components will be completed in early 2009. Once completed, the plan will be submitted to the IGIC Board at the next board meeting.

As the State Geographic Information Officer (GIO), Jim Sparks he is willing to serve as the official steward for the NHD. As such, he will serve as the point of contact for the State and the formal resting point for stewardship activities. However, he will need resources to manage the stewardship activities. He will work closely with and rely on the Workgroup for assistance. Jim will review examples of MOUs between the US Geological Survey and states, and draft an Indiana version for the Workgroup to review. Dave Nail and Cindy Martin will assist as needed. The Watershed Boundary Dataset (WBD) will likely be integrated into the NHD, and its stewardship should also be included in the MOU.

Cindy Martin, Dave Nail, and Bruce Nielsen are attending the National Hydrography Dataset (NHD) Stewardship Conference in Colorado this month. They will report on the conference at the May Workgroup meeting.

February 16, 2009

A draft of the workflow, data update/maintenance, and recommendations for data stewards has been developed. These draft components will be completed in early 2009. Once completed, the plan will be submitted to the IGIC Board at the next board meeting.

January 15, 2009

The Waters Workgroup met on October 30th and December 10th. The Stakeholder Survey Report was approved and the Data Plan draft has been updated to include its summary. A document addressing the group’s recommendation for “Improving the NHD” was drafted and reviewed, and the second draft has been distributed. One of the data stewards for the Minnesota NHD addressed the group at the 12/10 meeting via WEBX. Mark Olsen (Minnesota Pollution Agency) shared how Minnesota adopted, updates, and distributes NHD data as the state’s water layer.

A subcommittee is currently drafting a report addressing workflow, including the following items: source data acquisition, prioritization of watersheds, incorporating non-NHD attributes needed for the Indiana Map, QA/QC, data distribution, and ongoing data maintenance. The entire workgroup will reconvene when the draft is completed.

2008 Project History

The Waters Framework Dataset Workgroup began 2008 with USGS training on maintenance of the National Hydrography Dataset. Several members of the workgroup participated. The training focused on edits needed to correct topological and network errors in the high-resolution NHD. Those who participated felt that the maintenance tasks will require ArcGIS editing skills and an inherent knowledge of Hydrography principles. Since the time of the training, USGS completed the ‘Maintenance Lite’ on Indiana’s sub basins.

The Stakeholder Requirements section of the data plan was completed in 2008. An online survey tool was used to gather information from stakeholders over the course of four months. Conclusions drawn from the survey:

  • Users of Waters Framework Data are a diverse group with diverse needs, but with a consensus that a variety of NHD and water-related data is a necessity for work being completed across the State.
  • Data from the NHD would seem to meet the needs of most users seeking the Waters Framework Data, if available at higher resolutions.
  • While the 1:24,000 scale of the high’resolution NHD meets the needs of many, most need data at a larger scale. Data at a scale of 1:6,000 would meet the needs of most, but a large percentage need data at a scale of 1:2,000 or better.
  • Needs for mapping can be met by providing shapefiles of statewide NHD lines, areas, water bodies, and points which can be downloaded from a state or IGIC website. These will be projected (UTM, NAD83) with a projection file included. Additionally, users will also be provided with how to work with projected data combined with non-projected data (e.g., using statewide shapefiles with USGS geodatabases in Geographic Coordinate System).
  • Needs for in-depth analysis and modeling could be met by the topology-based feature classes for watersheds which can be downloaded from the USGS NHD website.

Data Enhancement Services, Inc. (DES) ran a pilot project on using 2005 digital orthophotography and local Hydrography vector data to improve the NHD. The process involved creating hydrographic data from the orthophotography and local vector data, conflating to it the attributes of the high-resolution NHD, creating the geometric network, and uploading it to the USGS NHD website. The test area was a section of Hamilton County. Results suggest that such a process would successfully upgrade Indiana’s NHD to a local resolution (1:2,400 scale) and significantly improve feature naming. Estimated cost is $1.2 million for the entire state. The Workgroup recommends that the process of using local resolution vector data, feature extraction, and conflation be implemented to improve and update the high resolution National Hydrography Dataset.

An updated draft of the Data Plan was posted in December.

October 16, 2008

DES, Inc. presented their findings on their pilot project to create hydrography data from the 2005 orthophotography and conflate to it the NHD attributes. The sample included an area within Hamilton County. Cost for a statewide project is estimated at $1.2 million using the 2005 DEMs and Orthophotos, and $1.5 million if statewide LiDAR data were available. The latter would improve completeness, positional accuracy, and currency. The pilot review, pilot report, and pilot qc design documents are available on the workgroup’s activities webpage,

The new NHD Maintenance Procedures Sub-group (Dave Knipe, Dave Nail & Phil Worrall) met on September 25th. They discussed creating a procedures document to help define the workflow for the full project. A basic outline of the workflow was defined and it will be presented to the full workgroup at the next meeting scheduled for October 30th.

August 21, 2008

The Waters Workgroup will be meeting on September 17th to discuss the stakeholders survey and the conflation pilot project.

June 19, 2008

The Waters Workgroup is working with Data Enhancement Services (DES), Inc. on a pilot project to enhance a portion of the high-resolution National Hydrography Dataset for Hamilton County. DES will conflate the high-resolution NHD to a combination of the 2005 digital orthophotography products (orthophotos, color infra-red, digital elevation model, digital surface model) and local Hydrography data from Hamilton County. The project should lead to a ballpark estimate for a statewide conflation project and also provide examples of differences between using the various data sources. Also, a subcommittee of the workgroup will be formed to analyze and report on the stakeholder survey results (71 respondents).

April 17, 2008

The Waters Workgroup is continuing its work toward updating the Waters Framework Data Plan. Several in the group participated in US Geological Survey (USGS) Training on Maintaining the National Hydrography Dataset. The training focused on repairing topology errors, and inconsistent naming issues. As a result of the training, fixes were made to several of the sub-regions, and USGS is working to verify and complete changes. A few sub-regions still need repairs. Further, long-term maintenance will involve repairing geographic and attribute errors.

As a result of the training, fixes were made to several of the subregions, and USGS is working to verify and complete those changes. A few subregions still need repairs. Further, long-term maintenance will involve repairing geographic and attribute errors. The group has also posted a web-survey to evaluate the needs of stakeholders. All who use water-related data are encouraged to complete the survey.

January 17, 2008

The Waters Workgroup is focusing on two key elements: creating the stakeholder survey and the US Geological Survey training for maintaining the National Hydrography Dataset. The latter is scheduled for January 15-17 at The Polis Center at IUPUI. Participants will include representatives from State agencies (Departments of Natural Resources and Environmental Management), local government (Hamilton County), watershed groups (St. Joseph River Basin Commission), universities (IUPUI), and IGIC. The workgroup also held a stakeholder survey subcommittee meeting focusing on both what information to gather and how to gather it.

November 15, 2007

The Waters Framework Data Workgroup is working on setting up a hands-on training session on National Hydrography Dataset Stewardship. The US Geological Survey will be conducting the training, likely to be held in January. The group is also working collecting information regarding water data user needs. The draft data plan will be available on the Workgroup website.

The Waters Framework Data Workgroup met on October 23rd to continue drafting the data plan. David Nail, US Geological Survey, presented an excellent review of the National Hydrography Dataset, including its feature classes and event themes. The group will now be focusing on identifying stakeholders and their needs. The next meeting is scheduled for November 30th in Indianapolis.

September 20, 2007

The Waters Workgroup held its first meeting on September 17th. The consensus was to adopt the high-resolution National Hydrography Dataset (NHD) for Indiana as the “starting point” for Indiana’s waters framework dataset. However, topics that need to be addressed are which of the high-resolution NHD layers to include, which attributes, and whether other layers need to be added. That topic will be one of the items for the next meeting. The group is now drafting updates to the 2001 plan. The next meeting is scheduled for 10:00 AM on Tuesday, October 23rd, at the NRCS Office in Indianapolis.
