The workgroup held a joint meeting with the Data Sharing Committee to work on the County Boundary pilot project.

June 21, 2012

The Workgroup got a jump start through the Data Sharing Committee Meeting on June 5th. Participants wanted to hear about the County Boundary Project and Cadastral Data Standards. Lorraine Wright gave webinar presentation detailing past Workgroup activities regarding the County Boundaries and how it will be built on the Tie Card Project Grid Points and the PLSS layers in the IndianaMap. The data standards portion of the discussion was tabled until the next meeting. Several people volunteered to help out on the County Boundary Project: Dave Estes – Allen County, John Howe – Gibson County, Steve Hook – Noble County, Shaun Scholer – Wayne County, and Bob Mueller – State Land Office.

Bob Mueller volunteered to collect some legal descriptions from the Indiana Acts. The descriptions will be accessible to Counties upon request until we get them posted on the IGIC Boundaries, Cadastral, PLSS Workgroup website.

County Boundary Pilot Project volunteers meet via phone conference on June 12th. Lorraine Wright and Bob Mueller stepped the volunteers through the legal description information available to them. Bob pointed out that counties should start with the 1852 Indiana Act to determine which corners define the boundary, because at the time it was the current description for all Counties. Once the points are extracted from that document and entered in a spreadsheet, Counties are to find any other legally binding descriptions, post them, and enter other corners from those descriptions into a spreadsheet. Once the corners are identified, the grid points that define the County Boundary can be selected out of the Grid Layer based on the legal descriptions. A discussion ensued regarding whether to use all grid points (approximate locations) or use the best available coordinates (geodetic coordinates in State Plane if available) in the County Boundary layer. Some counties want the best available coordinates and others want a static boundary that defines the county boundary so that all GIS layers could be snapped to the boundaries. Two main issues were discussed:

1. County Boundary maintenance of GIS layers becomes a major problem trying to keep up with changes as County Boundaries are revised with better coordinates.
2. County Surveyor’s maintain the geodetic coordinates for the County. County Surveyor’s would not want the geodetic coordinates (probably State Plane) mixed with approximate UTM Grid Points when defining the County Boundary.

Dave stated we all need to be in agreement as to how to proceed with this project and define why we are developing the County Boundary layer. Since there was some disagreement in determining the coordinates to be used, we did all agree that in these initial steps we would define the County boundary using the corners from the legal description and identify them by using the State Corner naming convention. There will be more discussions regarding coordinates.

The Marion County Tie Card layer for the IndianaMap is in the process of being updated with the Statewide grid point naming convention. Lorraine Wright also received a request asking if there are any right-of-way standards that have been developed. She is researching the question and will provide the information to the requestor and the Workgroup.

February 16, 2012

The Workgroup developed its goals for the upcoming year:

  • Link the State Tie Card Naming Convention to scanned County Tie Cards
  • Add new county data to the Surveyor Tie Card Layer on the IndianaMap
  • Locate County legal descriptions
  • Develop point and line County Boundary shapefiles for Counties using County legal descriptions cited in legal references

December 8, 2011

The Workgroup did not meet during this period.

October 20, 2011

The Workgroup did not meet during this period.

April 28, 2011

There were no Workgroup meetings in March or April, 2011. Some members continue to work on the new GIS County Boundary file development and the Tie Card Project.

Lorraine Wright, Chair, gave a presentation to the County Surveyors Association on March 9, 2011 at the Purdue Road School Conference in Lafayette, Indiana. The title of the presentation was “Corner Stone Ties Project” (also referred to as the Tie Card Project). She also provided a demonstration of how to use the Renaming Software created for the project.

December 6, 2010

The Workgroup met on November 10, 2010. The State Land Office has a new Director, Robert Mueller. Robert attended the November 10th Workgroup meeting and volunteered to work with the Workgroup as much as possible.

Tie Card Project – Marion and Wayne County Tie Card layers were completed September 30 and October 13, 2010 respectively and posted on the IndianaMap October 26, 2010. Hamilton and Hancock Counties are nearing completion.

County Boundary GIS file – The new State Land Office Director, Robert Mueller has volunteered to work on creating the new GIS digital county boundary layer using the County Boundary legal descriptions. The Workgroup has already developed the process of creating the boundary layer. Lorraine will provide Robert with the training and information he needs to proceed.

Presentations – Lorraine gave a presentation, “A State-wide View of Section Corner Data”, about the Tie Card Project at the State of Indiana GIS Day, November 9, 2010. The power point presentation is available on the Workgroup website.

October 21, 2010

The Workgroup met on September 8, 2010. There was no meeting in October. Lorraine Wright is working with the County Surveyor and GIS staff to complete Tie Card integration on the IndianaMap for Wayne, Marion, and Hancock counties. Lorraine has sent the Tie Card layer for Wayne County to IGS last week for posting to the IndianaMap.

Lorraine is also working with workgroup members from Marion, Hancock and Hamilton County Surveyor department to prepare a pilot of IGIC’s new County Boundary GIS layer. This pilot will be demonstrated late this year in a special presentation to our County GIS Coordinators.


August 19, 2010

The Workgroup met on June 9th and July 14th to set the direction of the work that is being done on several different projects:

Tie Card Project – Currently working with data received from Marion, Hancock and Wayne Counties as well as data from the Hamilton County website to get the Tie Cards linked to the Grid Point layer. Once all are linked, the layers will be pushed to IGS so they can add the counties to the IndianaMap Tie Card layer. The goal is to get the four new county Tie Card layers sent to IGS for posting by September 8th.

The Grid Point Layer – The layer is being updated to incorporate points that were missing in Wayne County. Lorraine Wright is testing a way to make it easier for the county to update the Tie Card layer by adding the Counties naming convention to the grid point layer. It is more time consuming up front but should be more efficient for updating their layer on IndianaMap.

County Boundaries – IGS is currently incorporating the Court Ordered Indiana-Kentucky boundary line into the Section, Township/Range, County and State Boundary layers. IGS identified an error in the Court Ordered Boundary line. Bob Wilkinson is working with the appropriate parties to see if the line should be officially changed.

Government Land Office (GLO) Records Project – Marion County is the pilot for this project. One Township with Federal GLO records and all of the Marion County GLO records were linked to the appropriate points. The Workgroup determined it would be best to link the GLO records to the Township polygons. Work is ongoing to revise how the GLO records are linked.


June 17, 2010

The Workgroup conducted meetings on April 14th, May 18th, and June 9th.

Tie Card Project – There are 8 counties participating and 21 counties interested in participating in the Tie Card Project. The eight participants counties are the original pilot counties (Newton, Bartholomew, Jennings) plus Delaware, Hancock, Marshall, Marion, and Wayne.

New County Boundary Polygon Layer for IndianaMap – IGIC and IGS meet on June 3, 2010 to discuss logistics of the various layers the Workgroup is working on for the IndianaMap. IGS volunteered to revise the IGS County Boundary Polygon Layer to include the court ordered, geodetically described, boundary between Indiana and Kentucky (Indiana’s southern boundary). Bob Wilkinson, DNR created a shapefile using court ordered coordinates. IGS will use the shapefile and court documents as needed to revise the IndianaMap layer. The IndianaMap southern County boundary polygon layers for Posey, Vanderburgh, Warrick, Spencer, Perry, Crawford, Harrison, Floyd, Clark, Jefferson, Switzerland, Ohio, and Dearborn will be revised. The revisions will begin in July. IGS will be revising the County, Township/Range, and Section layers. The revised County Boundary layer will include a few additional attributes. The layer names will remain the same and the original layers (currently on the IndianaMap will be archived for historic reference).

New County Boundary Point and Line Layers for IndianaMap – Lorraine Wright is using the legal descriptions of the counties to identify the corners and lines that make up the county boundary. The second county is nearing completion.

Government Land Office (GLO) – Original Indiana Surveying Notes and Plats will be linked to the IGS Township/Range layer. These include: GLO National Archives, GLO State Archives and GLO County Archives.


April 15, 2010

The Workgroup conducted meetings on February 16th and March 17th, and:

  • Completed the Cadastral, Boundaries, PLSS Worklgroup Report, February 11, 2010, summarizing the 2009 Workgroup accomplishments and the work proposed for 2010.
  • Developed a Data Integration Plan dated April 1, 2010 and provided it to the IGIC Director and the GIO.
  • Continues to work on the new Statewide County Boundary polygon, point and line layers. The Marion County legal description was used to define the first county boundary by PLSS corners and section lines. The boundary is mapping grade quality.
  • Lorraine Wright gave a presentation, ‘IGIC Cadastral, Boundaries, PLSS Workgroup Update’ on February 24, 2010 at the IGIC 2010 Annual GIS conference.

February 22, 2010

The Workgroup is creating a new statewide county boundary layer that includes legal references to the boundary attributes, county website links and other relevant attributes. Harvested County data will be compared to determine if counties boundaries match. The new statewide county boundary layer will be used as a tool in comparing the data. The group will be also be working with County Surveyors on the Tie Card Project and identifying PLSS corners that define county boundaries.
