Accomplishments 2009• CAP Grant received for data sharing

initiative • Developed the initial criteria needed to

create an official state-wide county boundary layer

• Legislation - Enrolled Act 530 passed. It establishes an Indiana-Michigan Boundary Line Commission. The Commission will oversee a retracement survey of the original 1827 Indiana-Michigan boundary and re-establish the Indiana-Michigan boundary line for the counties along the Indiana-Michigan border.



Accomplishments 2009 County Boundaries –

Compared all existing state-wide county boundary layers for source scale, accuracy currently being used

Identified the IGS county boundary layer as the best available most accurate state-wide county boundary layer

Added attributes to new State-wide County Boundary layer



Accomplishments 2009 County Boundaries –

Began developing list of PLSS corners and lines that define county boundaries (based on legal descriptions)

Identified the Newberry Library as the most current information regarding legal references to County Boundaries at the state level.

The Newberry information contains more current legal references than the County Boundaries Book.



Accomplishments 2009• Tie Card Project

Created a Tie Card Video – includes a summary of IGIC and the process steps to participate in the Tie Card Project

Prepared letter to send to County Surveyors to ask for participation in project

Working with County Surveyors Association



Accomplishments 2009 Updated website to include:

Standards◘ National Cadastral Standards ◘ Jurisdictional Boundaries Standards

County Boundary◘ Boundary legislation ◘ Historic County Boundary information ◘ IN-Kentucky boundary shapefile and all

documentation ◘ Surveyors information

Tie Card Project - Video



Planned for 2010• New State-wide GIS County

Boundary Support the creation of a new

authoritative GIS digital County Boundary shapefile for the IndianaMap (FDGC CAP Grant). Define, collect and document all data

sources (inventory County Boundaries). Design and document the new county

boundary shapefile(s). Develop, document and test a

methodology to create the new county boundary shapefile(s).

Develop, document and test a methodology to update/maintain the new county boundary shapefile(s).



Planned for 2010• New State-wide County

Boundary Develop FGDC compliant metadata

for the new county boundary shapefile(s).

Identify requirements (types of data) needed by Surveyors and the GIS initiatives to be viewed in the INMAP:

◘ County Boundary and PLSS points.

Data Model Data Integration Plan



Planned for 2010• New State-wide County

Boundary Support QA/QC efforts for the

harvested county jurisdictional boundary and parcel data published to the IndianaMap Investigate, define and document

QA/QC issues to report Develop, document and test a QA/QC

methodology



Planned for 2010 Tie Card Project

Send letter to County Survey – invitation to participate in the Tie Card Project

County Boundary Corners a. Identify corners



• Tie Card Pilot Project Summary Created Grid Point and Tie Card GIS layer

Created a state-wide naming convention for the Grid Points

Created a computer generated set of points representing an approximation of the PLSS ¼, ¼, ¼ corners

Created Renaming Software to be used to link a scanned image of Tie Card to a Grid Point

Setup the process to create a State-wide Tie Card GIS layer

Worked with Bartholomew, Newton and Jennings Co during the pilot project to put their Tie Cards on the IndianaMap website



Tie Card Project• Grid Point file naming convention

IN02_T23NR06E03_08

State Name and Prime Meridian – IN02 Township number - T23 Township direction – N Range number – R06 Range direction – E Section – 03 Grid Number – 08 (Grid numbering system

begins with 00 in upper left hand of section and ends in 80, bottom left corner)


Tie Card Project

Grids points were created for ¼, ¼, ¼section corners

New Tie Card Project activities• Created a video

Summary of IGIC and step-by-step instructions on how to participate in the Tie Card Project

• Working with County Surveyor’s Will be sending out a letter to County Surveyor

inviting them to participate in the Tie Card Project

Implement Tie Card Project in interested counties

• Developing a process to link to: County’s Tie Card database Link to County’s Tie Card images on their

website Using Data Sharing initiative processes Similar to the methods being used to harvest

other county datasets



County Boundary • Inventory of County Boundary

sources Census Newberry INDOT IGS 92 Individual County boundaries Southern Indiana Boundary

Court case, coordinates on paper, DNR created shapefile

Northern Indiana boundary retracement survey – ongoing



County Boundaries• Determine which county boundary

should be used as the state-wide County boundary layer County Boundary will be used to compare

harvested county data (needed common boundary)

Selected IGS County Boundary Best scale available at state-wide level Good metadata New attributes will be incorporated as identified

by Surveyors and GIS professionals◘ Legal references◘ Website links: County Surveyor and County GIS ◘ Coordinate, Datum, Zone◘ Source◘ Other



County Boundaries• New State-wide County Boundary

(polygon) Attributes being added Will be released onto IndianaMap as

soon as it is completed

• Next step – County Boundary with Point and Line Feature level data based on legal descriptions Acquire County boundary legal

descriptions Define PLSS corners and Section lines

that define boundary Associate the legal information to the

Grid Points and IGS Section line segments to get feature level dataset



Sources for County Boundary Legal Descriptions

• County Boundaries Book Legal references for County boundary

descriptions Published in 1933

• Newberry Library History of Indiana Counties Historical and current Indiana boundary

shapefiles Individual County Boundary Chronologies

through 1981

• Individual County Surveyor Offices



County Boundary Legal Description• Define GIS points and lines that

make up a county boundary using legal description

• Need to be able to change boundary points if GIS data is improved and need to have the common reference corners between counties identified so we are linking the common corners



• Counties boundary changes since 1900 (source Newberry Library)

8 March 1923 Kankakee River boundary of JASPER, LAKE, NEWTON, and PORTER adjusted to match ditching of streambed [not mapped]. (Ind. Acts 1923, 73d sess., reg., ch. 164, secs. 1-3/pp. 464-465)

2 March 1925 Kankakee River boundary of LA PORTE and STARKE adjusted to match ditching of streambed [not mapped]. (Ind. Acts 1925, 74th sess., ch. 41, secs. 1-3/pp. 122-123)

9 March 1931 LA PORTE exchanged small areas with ST. JOSEPH. (Ind. Acts 1931, 77th sess., ch. 115, secs. 1-4/pp. 450-452)

27 March 1979 Boundary between CLARK and WASHINGTON was redefined [no change]. (Ind. Acts 1979, 101st gen. assy., 1st reg. sess., pub. law no. 156/p. 714)

31 August 1981 Boundaries of FULTON, MARSHALL, and ST. JOSEPH clarified [no change]. (Ind. Secretary of State, correspondence, 13 Jul. 1990; Ind. Acts 1980, 101st gen. assy., 2d reg. sess., pub. law no. 212, secs. 1-2/pp. 1682-1685)



County Boundary legal descriptions from 1981• As a result of Public Law number 212: • County surveyors were required to file with

the Indiana Secretary of State accurate legal descriptions of their counties as of 31 August 1981 and to report any later alterations within 30 days of the effective date of change.

• Apparently the county lines have remained stable because no changes were reported to the Secretary of State's office between 31 August 1981 and 1990. (source Newberry)

• Trying to locate 1981 County Surveyors reports with legal descriptions or the most current County boundary legal description



County Boundaries – Feature level data

• Correlate County boundary Section corners with Grid Points

• Correlate County boundary Section lines with IGS section lines

• Create point and line features that define the County Boundaries


Grid points used for locating section cornersthat define County Boundaries

(00, 04, 08,36, 40, 44,72, 76, 80)


Locate the Legal County BoundaryDescription


Copy the PLSS corner referencesto a database


Legal PLSS County corner description Grid point Names

Copy and paste corner descriptionsfrom the counties legal description intotable

Correlate Grid Point namingconvention associated with PLSS corner



• Each section corner can have up to 4 grid points The Grid point description depends

on which section the PLSS corner was surveyed from80 72

08 00Each Grid Pointwould have a different T,R, Section reference


Identify sectionson each side of the IGS Countyboundary line



Marion County

Correlate the legal corners that define the County Boundarywith the Grid Points




Select outthe Grid Points associated with the legal corner references


The Section lines provide a line layer database for the County Boundary

Marion County



Select out the Section line segmentsassociated with the legal references

You now have a point and line layer describing the County Boundary

• Cadastral (Parcel) data Counties are sharing data through

the Data Sharing Initiative Harvested data is being posted to

Indiana Map The New State GIS County Boundary

layer will be used in the support QA/QC efforts for the harvested county jurisdictional boundary and parcel data published to the IndianaMap


County Boundary (red)Parcel data (tan)




• County Boundary’s from Counties Individual County Boundary data

may be more accurate than the New State-wide County Boundary

Plans are being developed on how use the best available boundary information

The Workgroup is putting together a Data Integration plan for the Boundary layers



Indiana Statewide Data Integration Plan

• Public Land Survey System (PLSS) Data

• Boundary Data• Cadastral (Parcel) Data

Overview itemsCurrent HoldingsData StewardsData StandardsData Distribution MethodsStrategic PlanDraft by April 1, 2010



Summary• Most boundaries are defined by PLSS

Township, Range, and Sections (some exceptions)

• Legal PLSS corner coordinates will eventually alter GIS County Boundaries, other jurisdictional boundaries, and parcel lines.

• Identifying the Boundary corners and section lines that define the legal County Boundary will help in aligning the GIS data in the future.

• All GIS data should be tied to the legally surveyed PLSS corners and section lines as described by the legal descriptions and surveyed by Surveyors.



• 2010 Meeting Schedule: Cadastral, Boundary, PLSS Workgroup
