Reference Center.     (1) There is created the Automated Geographic Reference Center as part of the division.     (2) The center shall: 

• (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;

History of Cadastral ProgramHistory of Cadastral Program

• State Legislature Appropriations:• FY1999 Rural County Assistance 200,000• FY2001 Cadastral 200,000• FY2002 Cadastral 200,000• FY2007 Cadastral 400,000• FY2008 Cadastral 400,000• U. S. Congress Appropriations:• FY2004 Cadastral 1,000,000• FY2005 Cadastral 300,000• FY2006 Cadastral 300,000• FY2007 Cadastral 50,000• FY2009 Cadastral 156,000• FY2010 Cadastral 750,000• FY2011 Cadastral 300,000

This process began with an appropriation from the State Legislature in 1998 and combination of state and federal

funds have gone to the rural counties since then:

Future of ProgramFuture of Program• Congressional leaders in Washington DC are

exploring ideas on ways to support and improve the Utah Cadastre.

• Leaders understand the importance of accurate cadastral data for administrative purposes.

FLAIR ActFLAIR ActFederal Land Asset Inventory ReformFederal Land Asset Inventory Reform

Recognized Problem: Existing inventories of federal land are outdated, inaccurate, and uncoordinated.

• 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 

• 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of the Interior to develop a multipurpose cadastre of Federal real property and identifying inaccurate, duplicate, and out-of-date Federal land inventories, and for other purposes.”

• 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.

• 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.

Local Government Local Government SupportSupport

• Support letter were written to Congress by Utah Association of Counties (UAC) and the Utah

League of Cities and Towns (ULCT)

• Local government leader realize the importance of maintaining and accurate cadastre to make educated decision for administrative purposes.

Cadastral Grant ProgramCadastral Grant Program• The State of Utah has the program in

place to accommodate the FLAIR Act. • The work to be performed is Cadastral

Surveying and Mapping of Public Land Survey System section corners and/or enhancing the statewide digital Cadastre.

• We need funding!

• Geospatial data is only as accurate as its base reference data

• Sharing quality reference data enhances everyone’s geospatial data investment

Data Collection ProcessData Collection Process

• Funds distributed to counties

• County, or their agent, collects monument data in the field

• Data submitted to the AGRC

• AGRC processes data and delivers to the BLM

• BLM then incorporates data into the GCDB

AGRC Data ProcessingAGRC Data Processing• AGRC combines

different data formats from individual counties

• Process, organize and store monument record sheets

• Fit county data to BLM standards

Data StandardsData Standards• AGRC is working to meet BLM data standards

• Standards make it easy to merge data into the State Geographic Information Database (SGID)

Updates to the GCDBUpdates to the GCDB

• Version 1.1 is now available– Labeled as: PLSSlayername_GCDB in the

SGID

• Next version 2.0 is scheduled for July 2011

• Changes in 2.0

Cooperative Federal and State effort:

-The Utah School and Institutional Trust Lands Administration (SITLA) revises this data regularly to reflect changes in State Trust Lands

-The BLM revises this data regularly to reflect changes in Federal Land.

-Other information is edited and updated as changes are notified by interested parties.

Updated every Monday on SGID (check Edit_Date field for the most

recent changes).

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.

Many different values for owner types

Not standardized between Counties

Too few values

Attribute discrepancies may exist!

For data that can be used and shared across the state there is a need to:

- Cooperate

- Collaborate

- Standardize

Improve over time

Adjust features based on a shift from old to new controlAdjust features based on a shift from old to new control

o Rubber sheeting method: VBA Script

o Need unique POINTID name for control points

o Script uses POINTID to move from old to new point locations

o Set a search tolerance -> too large and it will not complete

o Run script on smaller areas

o Investigate old vs. new PLSS points -> distance moved

o Extra pre-processing work for boundaries that should not be moved in this process

o Montana workflow: http://giscoordination.mt.gov/cadastral/AdjustingDatatoGCDB.asp
