  3. Cadastral, Boundaries, PLSS Workgroup Projects Tie Card Project – GIS PLSS Surveyor Tie Card Layer (INMAP) State-wide naming convention enables uniform look and feel across the state Helps in identifying corners to use in revising GIS PLSS layers New GIS County Boundary - Point, Line, and Polygon Layers Pilot – Five Counties: Allen, Gibson, Noble, Wayne, Marion Government Land Office (GLO) Records IGIC Workgroup focusing on GLO state records Eventually like to have GLO federal, state, & county Records linked to GIS IGIC Cadastral, Boundaries, PLSS Workgroup Lorraine Wright, IDEM May 7, 2014

  4. IGIC Cadastral, Boundaries, PLSS Workgroup Tie Card Pilot Project Components • Grid Points – (approximate ¼ section. Sec, T,R) • Statewide Grid Point Naming Convention • IN02_T23NR06E03_08 • Scanned Tie Cards • Renaming Software (need PDFs & Adobe Reader) • Database Table (Access) provided with software • Automatically created when using Renaming Software • Database should include Tie Card hyperlink • Click on map hyperlink and see scanned Tie Card pop-up • Training materials on website along with a video step by step instructions • OR (next page) Lorraine Wright, IDEM May 7, 2014

  5. IGIC Cadastral, Boundaries, PLSS Workgroup Tie Card Pilot Project • The County • FiveCounties created databases with county hyperlinks to Grid Points/or County corners • Added the state-wide file naming convention to county data (hyperlinked Tie Card to Grid Point) and posted on IndianaMap • Next step: New Counties can share their info on county’s Data Sharing WMF/WSF website • County data can be included on IndianaMap on the “PLSS Surveyor Tie Cards” Layer Lorraine Wright, IDEM Mary 7, 2014

  6. Tie Card Project Layer

  7. IGIC Cadastral, Boundaries, PLSS Workgroup Building New Authoritative GIS County Boundary Layer for Indiana Based on County Data and County Participation Developed a disclaimer for layer Location of the points in this GIS County Boundary Layer are approximate and should not be used for surveying and are NOT APPROVED by a COUNTY SURVEYOR for surveying purposes. Contact the County Surveyor’s Office when conducting research for surveying. Lorraine Wright, IDEM May 7, 2014

  8. IGIC Cadastral, Boundaries, PLSS Workgroup New GIS County Boundary - Why? • Need to match GIS data across counties by using a common boundary • Federal GIS data mandates (use standards) • State GIS data efforts are to have seamless data across county boundaries • County 911 calls – across adjacent counties • Match Boundaries – across adjacent counties • Civil Township • County Boundary • Parcel Boundary (adjoining counties) • PLSS Boundaries • Street/Centerlines • Other Lorraine Wright, IDEM May 7, 2014

  9. County Boundary – Who is responsible for what • State Land Office - State Boundary • County Surveyor - County Boundary • Census • National Data Steward, NSDI • BLM & Census working together (PLSS and Boundaries) • Indiana Certification Officer (certifies boundaries) • Indiana Geographic Information Council (new GIS County Boundary) Lorraine Wright, IDEM May 7, 2014

  10. Census - BackgroundBoundary & Annexation Survey (BAS) Census collects boundaries as of January 1 each year annexations, de-annexations, incorporations, mergers Survey counties, MCDs (townships) & places (cities, towns, villages) and AIAs: Indiana: 568 Places Nation: 19,519 Places 1,008 Townships Townships: 16,360 92 Counties Counties: 3,031 Two “parts” to BAS: 1)provide geospatial changes (change polygons in BAS TIGER file, not just submitting your file) 2) provide legal documentation for changes Can also provide boundary corrections, not just the legal changes (more on this shortly) Gail A. Krmenec & Lorraine Wright, IDEM May 7, 2014

  11. Census - What is County ConsolidatedBoundary & Annexation Survey (C-BAS)? • County responds to BAS for governments within the county (entities must agree) • Not all entities in county have to agree to consolidation for county to be part of County Consolidated BAS universe

  12. Census - County Consolidated BASBenefits • (Most) counties can participate digitally • Counties may already collect and maintain the most up-to- date boundary information for entities in county (if not, this is a great way to get it) • Provides a service to the entities in the county • Provides continuity of BAS contacts and response as administrations, staff change in local governments • Counties know BAS program, requirements, what to do!

  13. Census - County Consolidated BASBenefits (con’t) • Reduces duplication of effort (with no C-BAS agreement in place, Bureau still surveys all entities, must rectify discrepancies) • Saves $$$ (i.e., taxpayer $) because Bureau has to engage fewer entities • Provides “Roll-Up” of boundaries to county (maybe State?) • Contributes to more accurate NSDI (Under OMB Circular A-16, Census Bureau is boundary steward for the Nation) • Can reduce inaccuracies (boundary corrections) Gail A. Krmenec & Lorraine Wright, IDEM May 7, 2014

  14. Census - Additional Datasets Desired with BAS Submission (new!) Parcel Dataset PLSS Dataset Both of these data sets can help the Bureau improve the overall boundary quality in TIGER. Note: used as reference for boundary alignment; parcel and PLSS data not inserted in TIGER; not released in public Census products Gail A. Krmenec & Lorraine Wright, IDEM May 7, 2014

  15. Census BAS • Interested in Consolidated BAS? Contact: Gail A. Krmenec U.S. Census Bureau gail.a.krmenec@census.gov (630) 288-9258 Gail A. Krmenec & Lorraine Wright, IDEM May 7, 2014

  16. IGIC Cadastral, Boundaries, PLSS Workgroup IGIC - New GIS County Boundary • Developed Pilot • Allen, Gibson, Marion, Noble, and Wayne • Designed Template • With disclaimer not to be used for surveying purposes • Attributes and Structure • Tested Gibson, Noble and Wayne via Data Sharing WFS • Maintenance - Developing processfor new GIS County Boundary layer for the IndianaMap Lorraine Wright, IDEM May 7, 2014

  17. County Boundary With Point Features Developed First Counties can use their best available data to create boundary points or use the Grid Points - County decides Use County Boundary Template (available to counties) Allows for documenting data collection process or County attributes mapped to Template attributes and then loaded into Template Acquire County Boundary legal descriptions Identify PLSS corners and section lines that define boundary Associate the legal description corners to boundary points in template Best available OR Grid Points Develop line and polygon layers from point layer New GIS County Boundary Share county best available data (points, lines, & polygon) through County Data Sharing WMF/WFS County Layers would be accessible on IndianaMap as County Boundaries become available IGIC Cadastral, Boundaries, PLSS Workgroup IGIC - New GIS County Boundary Design/Process Lorraine Wright, IDEM May 7, 2014

  18. Process for New GIS County Boundary • County Legal Description • Historical descriptions in Dropbox folder • Talk with county surveyor to see if there is a newer description (if so, send copy to Lorraine) • Used as attributes in the template • Identifies the original corners used to define county boundary Lorraine Wright, IDEM May 7, 2014

  19. Wayne County Legal Description Information In Template

  20. Process/Documents for Reference(Dropbox) • Grid Point Layer provides State-wide Naming Convention (PLSS) • Located in Dropbox Folder • Still developing Statewide Name Convention for counties containing Non-PLSS data Lorraine Wright, IDEM May 7, 2014

  21. County Web Feature Service (Data Sharing Agreement) • Currently contains: • Local governmental unit boundary data • Boundary Type (municipality, precinct, fire, school, tax districts, etc.) • Boundary Name (name/identifier of municipality, precinct, fire, school, tax districts, etc.) Lorraine Wright, IDEM May 7, 2014

  22. Process/Documents for Reference(Find in Dropbox) • County contact needs access to Dropbox • Send Phil Worrall email to request access to folder • Identify County Name, Contact name , and Dropbox County Boundary access in email subject line Lorraine Wright, IDEM May 7, 2014

  23. Access the Template and Guidance Documents Dropbox - https://www.dropbox.com/ ‎ Lorraine Wright, IDEM May 7, 2014

  24. Dropbox – IGIC County Boundary https://www.dropbox.com/home#!/home/IGIC%20-%20County%20Boundary

  25. Process/Documents for Reference(Dropbox) • Attribute Description Document (in Word) • Explains types of information and choices • Attribute Description Table • Name • Field type • Field length Lorraine Wright, IDEM May 7, 2014

  26. Process • Locate and download Geodatabase Template or Template Table format (Dropbox) • Extract County Grid Points for County • GridPt layer provides naming convention • Used in Template Lorraine Wright, IDEM May 7, 2014

  27. Process • Map County Attributes to Template Attributes • See Reference Documents • ArcGIS users - Import County Data into Geodatabase • Other GIS software users – Import County Data into Template Table format Lorraine Wright, IDEM May 7, 2014

  28. IGIC Cadastral, Boundaries, PLSS Workgroup New GIS County BoundaryDesign/Process • Common boundary lines • Both adjacent County’s to determine best • common boundary line • Communication • Between the county surveyor, GIS staff and • others county offices important part of this • process Lorraine Wright, IDEM May 7, 2014

  29. County Web Feature Service (Data Sharing Agreement) • “New GIS County Boundary” - place on the Web feature service as an independent layer • County discussion • Will county retire previous County Boundary layer? Lorraine Wright, IDEM May 7, 2014

  32. IGIC Cadastral, Boundaries, PLSS Workgroup Newest Project –Land Survey Records Documents are the basis for Indiana’s land system: • Original Field Notes* • Federal Transcribed Field Notes • State Transcribed Field Notes* • County Transcribed Field Notes • Plat Maps Each set was transcribed by different people at different times and may have differences in the information. *Project Focus Lorraine Wright, IDEM May 7, 2014

  33. IGIC Cadastral, Boundaries, PLSS Workgroup IGIC & State Archives –State Government Land Office Land Survey Records Pilot Project Project Goal • Scan the State Archive documents (State Original and Transcribed Field Notes and Plat maps), • Name the digital files to be consist with the original index naming convention, and then, • Link the scanned images to the PLSS section line layer or other non-PLSS units (ex: Land Grants) as layers on IndianaMap.
