  2. 2. Outline <ul><li>Introduction to State Cadastral Efforts (Sean) </li></ul><ul><li>Enhancing the Public Land Survey System and Live Demo (Keaton) </li></ul><ul><li>Building a Statewide Parcel Layer (Rick) </li></ul><ul><li>Vertical Integration of County, State and Federal Parcel (Lina) </li></ul>
  3. 3. State Code – PLSS <ul><li>63F-1-506.    Automated Geographic Reference Center.      (1) There is created the Automated Geographic Reference Center as part of the division.      (2) The center shall:   </li></ul><ul><li>(vii) facilitate and integrate the collection efforts of local government and federal agencies for data collection to densify and enhance the statewide Public Land Survey System reference network in the State Geographic Information Database. </li></ul>
  4. 4. State Code - Parcels <ul><li>63F-1-506.    Automated Geographic Reference Center.      (1) There is created the Automated Geographic Reference Center as part of the division.      (2) The center shall:   </li></ul><ul><li>(vi) coordinate with county recorders and surveyors to create a statewide parcel layer in the State Geographic Information Database containing parcel boundary, parcel identifier, parcel address, owner type, and county recorder contact information; </li></ul>
  5. 5. History of Cadastral Program <ul><li>State Legislature Appropriations: </li></ul><ul><li>FY1999 Rural County Assistance 200,000 </li></ul><ul><li>FY2001 Cadastral 200,000 </li></ul><ul><li>FY2002 Cadastral 200,000 </li></ul><ul><li>FY2007 Cadastral 400,000 </li></ul><ul><li>FY2008 Cadastral 400,000 </li></ul><ul><li>U.

  6. 7. Future of Program <ul><li>Congressional leaders in Washington DC are exploring ideas on ways to support and improve the Utah Cadastre. </li></ul><ul><li>Leaders understand the importance of accurate cadastral data for administrative purposes. </li></ul>
  7. 8. FLAIR Act Federal Land Asset Inventory Reform <ul><li>Recognized Problem: Existing inventories of federal land are outdated, inaccurate, and uncoordinated. </li></ul><ul><li>On March 5, 2008, U.S. Representative Ron Kind (D-Wis.) and Chris Cannon (R-Utah) introduced the Federal Land Asset Inventory Reform (FLAIR) Act  </li></ul><ul><li>FLAIR Act is “to improve Federal land management, resource conservation, environmental protection, and use of Federal real property, by requiring the Secretary of the Interior to develop a multipurpose cadastre of Federal real property and identifying inaccurate, duplicate, and out-of-date Federal land inventories, and for other purposes.” </li></ul><ul><li>The FLAIR Act, if passed, would require the Department of Interior (DOI) to develop a single, multipurpose cadastre of federal real property and to pursue contracts for surveying and mapping services. </li></ul><ul><li>This bill would require that the DOI integrate with and leverage to the maximum extent of current cadastre activities of units of state and local government. </li></ul>
  8. 9. Local Government Support <ul><li>Support letter were written to Congress by Utah Association of Counties (UAC) and the Utah League of Cities and Towns (ULCT) </li></ul><ul><li>Local government leader realize the importance of maintaining and accurate cadastre to make educated decision for administrative purposes. </li></ul>
  9. 10. Cadastral Grant Program <ul><li>The State of Utah has the program in place to accommodate the FLAIR Act. </li></ul><ul><li>The work to be performed is Cadastral Surveying and Mapping of Public Land Survey System section corners and/or enhancing the statewide digital Cadastre. </li></ul><ul><li>We need funding! </li></ul>

  18. 19. Live Demo PLSS Web App
  19. 20. Vertical Integration of Parcels Attribute Comparison Public Land Survey System (GCDB) Land Ownership Boundaries (includes State and Federal Parcels) County Parcels
  20. 21. Land Ownership Status and Areas of Responsibility for the State of Utah SGID93.CADASTRE.LandOwnership <ul><li>Cooperative Federal and State effort: </li></ul><ul><li>The Utah School and Institutional Trust Lands Administration (SITLA) revises this data regularly to reflect changes in State Trust Lands </li></ul><ul><li>The BLM revises this data regularly to reflect changes in Federal Land. </li></ul><ul><li>Other information is edited and updated as changes are notified by interested parties. </li></ul><ul><li>Updated every Monday on SGID ( check Edit_Date field for the most recent changes ). </li></ul><ul><li>Vertically integrated with the November 2006 version of GCDB </li></ul>
  21. 22. Land Ownership Status and Areas of Responsibility for the State of Utah SGID93.CADASTRE.LandOwnership *SITLA Layer File (STATE_LGD ) Fields OWNER codes Highest level owner of parcel Agency level owner of parcel *SITLA – School and Institutional Trust Lands Administration Entity with Administrative Jurisdiction of parcel General land management designation for parcel SITLA Legend codes Utah BLM Legend codes National BLM Legend codes Federal administrative names State administrative names GIS calculated acres Date of update to parcel Sample Attribute Combination #1 Agency may differ from whom administers (ADMIN) the parcel. The Federal BLM office may lease an area to the Utah State Parks Department for use as a recreational area. The owner is the federal, the federal agency responsible for the land is the BLM but the Utah State Parks Department is the administrators of the land because the land has been designated as a state park and recreation area. Sample Attribute Combination #2
  22. 23. Land Ownership and County Parcels Owner Type values – a comparison Land Ownership Owner Type Values County Parcel data sources Sample Owner Type values Many different values for owner types Not standardized between Counties Too few values for owner type? Attribute discrepancies may exist! Land Ownership County Parcels For data that can be used and shared across the state there is a need to: - Cooperate - Collaborate - Standardize Improve over time
  23. 24. Land Ownership, County Parcels and the PLSS Vertical alignment Land Ownership: Integrated with the November 2006 version of GCDB -> few County control corners in the 2006 version Need to move to the newest version of GCDB -> more County control points, improved dataset
  24. 25. Land Ownership Chasing the PLSS
  25. 26. Land Ownership Integrated to 2011 version of GCDB
  26. 27. Adjust features based on a shift from old to new control <ul><li>Rubber sheeting method: VBA Script </li></ul><ul><li>Need unique POINTID name for control points </li></ul><ul><li>Script uses POINTID to move from old to new point locations </li></ul><ul><li>Set a search tolerance -> too large and it will not complete </li></ul><ul><li>Run script on smaller areas </li></ul><ul><li>Investigate old vs. new PLSS points -> distance moved </li></ul><ul><li>Extra pre-processing work for boundaries that should not be moved in this process </li></ul><ul><li>Montana workflow: </li></ul>
  27. 28. SITLA Development parcels The Parcel Editor Tools and Parcel Fabric - part of core ArcGIS Desktop software SITLA GIS Group reviews and incorporates survey plat legal descriptions to parcel layers - A need to more efficiently review plat information and to store the description calls
  28. 29. SITLA Development parcels Review of legal description Creating Parcels - Import Traverse File - Append XML File - Enter Parcel traverse - Construct Parcel (i.e. from AutoCAD lines) And more (See Esri Help Documentation) Check Misclosure - provides a first-level quality check Parcel dimensions stored in attribute table
  29. 30. SITLA Development parcels Join Parcel to Fabric and Run LSA Joining to Fabric Check Join Residual – the Parcel Fit second-level quality check Run Least Squares Adjustment (LSA) on joined parcels comprehensive level quality check - the parcel dimensions are used together with the control points to improve the accuracy
  30. 31. SITLA Development parcels Tie to PLSS Corners Create Parcel Check Closure Join to Fabric Tie to PLSS corner Join to adjacent parcels Check Join Residual - Fit After Join Export description to XML files to share More about the parcel fabric -> Thursday 8:30 – 10 am ArcGIS 10 for Land Records (Esri)
  31. 32. Vertical Integration of Parcels Improving Over Time
