  1. Geodetic, ISPLS, HARN Framework Workgroup/Committee Tie Card Project Lorraine Wright INGISI representative

  2. 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

  3. 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

  4. Surveyors • Survey data is the basis for: • Geodetic Control • Cadastral - PLSS Control • Boundary information

  5. 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

  6. 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

  7. 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

  8. Equipment for the Pilot • INGISI and ISPLS worked together to purchased equipment through a grant • 2 laptops • 2 scanner/printer/copiers were purchased

  9. Pilot Project -Phase I Develop a file naming conventionfor the scanned tie cards that could be utilized State-wide

  10. 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

  11. 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)

  12. Phase II • Develop a Point Grid that could be used to link to the scanned tie cards

  13. 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.

  14. Phase II • Develop the GIS Point Grid Map

  15. Phase III • Scan tie cards

  16. Phase IV • Rename scanned tie cards with a meaningful name • file naming convention

  17. Phase V • Link the scanned images to the Tie Card - Point Grid GIS Layer

  18. Cookbook • Develop a cookbook defining process: • Scan tie cards • Rename scanned tie card • Link tie cards to Point Grid map

  19. 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

  20. 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
