Geodetic, ISPLS, HARN Framework Workgroup/Committee Tie Card Project Lorraine Wright INGISI representative
Participants • INGISI members (state, county, local, private) • Indiana Society of Professional Land Surveyors (ISPLS) • Office of the Indiana State Geodetic Advisor (HARN) • Indiana County Surveyors Association • Private Companies • Indiana University and Indiana Geological Survey
Purpose • Original purpose: to develop a Statewide Framework of Geodetic information • The federal government maintains most of the data • Link to the National Geodetic Control site for Geodetic Control
Surveyors • Survey data is the basis for: • Geodetic Control • Cadastral - PLSS Control • Boundary information
Purpose • Develop a state-wide framework layer of PLSS corner information - Cadastral Framework • The workgroup determined that the Tie Card Project would be the most beneficial project in the absence of coordinate data
Purpose • Develop a process to enable Counties (to link the Tie Cards to a GIS • The Tie Card is the basic building block (documentation) for the PLSS Corner
Pilot Project • Develop a pilot project with a county • Bartholomew County agreed to be the pilot county • Work through the entire process and document it so other counties would benefit from having the process developed
Equipment for the Pilot • INGISI and ISPLS worked together to purchased equipment through a grant • 2 laptops • 2 scanner/printer/copiers were purchased
Pilot Project -Phase I Develop a file naming conventionfor the scanned tie cards that could be utilized State-wide
File Naming Convention • Surveyor use descriptions to describe a Public Land Survey Section corner (ex. NE 1/4, NE 1/4, NE1/4, Section 03,T23N, R06W
File Naming Convention • IN02_T23NR06E03_08 Computer File Name will include – (example) • 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 0 in upper left hand of section and ends in 80, bottom right corner)
Phase II • Develop a Point Grid that could be used to link to the scanned tie cards
Phase II • Develop a method to be able to link the scanned Tie Cards to a map • Renaming Software developed by Brian Wood, Paul I. Cripe, Inc.
Phase II • Develop the GIS Point Grid Map
Phase III • Scan tie cards
Phase IV • Rename scanned tie cards with a meaningful name • file naming convention
Phase V • Link the scanned images to the Tie Card - Point Grid GIS Layer
Cookbook • Develop a cookbook defining process: • Scan tie cards • Rename scanned tie card • Link tie cards to Point Grid map
Pilot Project • Status • Bartholomew County Pilot • Currently data being verified for quality and completeness • Will deliver the project to the County in an ArcReader Project • All the data can be included in their GIS or can be used as an ArcReader Project
Statewide Project • Data Storage – possibly IU Mass Storage • State-wide Tie Card Layer • Combine Tie Card Layer with • Data from Counties that already have data on their website
