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 convention for 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
