The Forgotten Frameworks - NSGIC
NSDI – The Forgotten Frameworks NSGIC Annual Meeting Charleston, South Carolina September, 2014 Agenda • Introduction - SDI Land Ownership Frameworks • Geodetic Control and Standardized Reference Systems • Administrative Boundaries • Parting Shots The Birth of the Cat The Forgotten Frameworks What the FGDC Didn’t/Still Doesn’t Understand CADASTRAL GEODETIC CONTROL GOVERNMENTAL UNITS Why People Forget They forget where they put things GOVERNMENTAL UNITS - 1997 CULTURAL AND DEMOGRAPHIC STATISTICS, 2008 Geospatially referenced data that describe characteristics of people: nature of structures in which they live and work; economic and other activities they pursue; facilities they use to support their health, recreational, and other needs; environmental consequences of their presence; boundaries, names, and numeric codes of geographic entities used to report information collected. GOVERNMENTAL UNITS AND ADMINISTRATIVE AND STATISTICAL BOUNDARIES - 2013 Source – FGDC Publications and Annual Reports Why People Forget They think they are done Fully or Substantially Enabled Counties with Accurate Positioning Source – 2008 FGDC Annual Report/NGS Scorecard Survey Why People Forget They are bored Source – Stu Kirkpatrick’s Mind Why People Forget They think that things are too big to fail NGDA Dataset Candidates by Theme as of September 2012. This chart reflects the proposed combination of the Cultural & Demographic Statistics and the Governmental Units Themes into a single Theme titled Governmental Units, and Administrative and Statistical Boundaries Source – 2012 FGDC Annual Report The Real Framework Land Records or Multi-Purpose Cadastre Control Cadastral -Survey -Photo Interpreted -Crowd Sourced Boundaries -Tax Parcels -Easements Right of Ways Cadastral Reference Grid -County -School -Forest Service Control Nancy Von Meyer Reference Systems • Geodetic Control • Cadastral Reference Grids • • • • PLSS – Montana PLSS – Utah Eastern states examples Managing Change • Other reference systems for boundaries – physical features, etc. Multi State Control Database • Geospatial Control – Points of common control to tie data themes together and to reference data to the earth. • Typically non-geodetic, but valuable • An aggregation of available control that can be harvested for a variety of applications including land records management.

Utah and Montana CadNSDI Today in many areas is ………… Why State Custodianship of CadNSDI? Angry Cat Every Sick Cat Needs a Vet (or two) Results Changing Workflows Managing Change The Cat Springs Into Action Land Records in Utah Jessica Kirby, State Trust Lands Bert Granberg, Utah AGRC Expectations Grow As GIS Products Mature • Enhanced Data sharing: infrastructure & processes • Greater data currency & data quality “This is great and all, but what I really needs is …” What is the PLSS? • A system for subdividing & describing land in the US • For many states, it’s ‘just’ the foundation of private land ownership – – – – – – State Boundaries Meridian Systems (origin & axes) Survey Monuments Townships (6 x 6 mile divisions) Sections (1 square mile) Section Divisions (Quarters, Quarter-Quarters, Special Surveys, etc) ( GCDB is the PLSS data product ) In short. A High Precision PLSS GCDB is… • the Key to… – – – – – Survey grade GIS boundary data Efficiencies in future surveying Minimizing property & jurisdictional disputes Better analysis and decision-making Economic activity Base Geographic Reference • Accuracy: geospatial data is only as accurate as its base reference data • Downstream ROI: Sharing quality reference data enhances EVERYONE’S geospatial data investment Aerial Photography + Utah GPS Reference Network Public Land Survey System (GCDB) Elevation Models State Geographic Information Database County/City Boundaries Ownership Boundaries County Parcels Utah-specific activity • County cadastral grants – Federal / State funding – Survey PLSS corner monuments • Real-time GPS base station network (sub cm) • Digital record of tie-sheet survey records – Online map for viewing and submission • State stewardship of Public Lands Ownership GIS layer History of Cadastral Program 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: Utah State Code – Parcel Rollup • 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: …. • (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; Corner Monuments PLSS App for Monument Record ‘Tie Sheets’ http://mapserv.utah.gov/PLSS/ How does the program work? • PLSS is used as a base layer to control other layers • Physical monuments drive location of boundary on the ground • Dependencies: • Municipal, County, Service District boundaries • and, of course, Parcels (county) and Land ownership (state) PLSS App - Data Standards • AGRC aligned with BLM cadastral data standards • Data standards make it easy to merge into the State Geographic Information Database (SGID) Utah’s RTK System: TURN GPS Network 400+ subscribers PLSS A-16 Stewardship Activities • BLM is designated NGDA (A-16) Steward • BLM oversees enhancement of the Geographic Coordinate Data Base (GCDB) – Conducts high precision surveys of ‘corner’ monuments for areas of interest on public lands – Contracts for inclusion of high-precision geographic coordinates into GCDB for surveyed corner ‘monuments’ – Contracts for mathematical adjustments to unsurveyed GCDB corner points – Seeks to publish GCDB updates for public use Land Records in Utah Land Ownership Status of Utah State Lead Stewardship is a Cooperative Effort! SGID10.CADASTRE.LandOwnership Cooperative Federal and State effort: •11 years of state and federal cooperation •The Utah School and Institutional Trust Lands Administration (SITLA) revises this data regularly, preforms the GIS adjustments and manages the cooperative project •SITLA coordinates State Lands Verification •BLM coordinates Federal Lands Verification •Private/ County from parcel roll-up Open data distribution: •Weekly updates consumed by State of Utah GIS Clearinghouse-SGID •Bi-monthly update to BLM – form internal use Working on a handshake! Land Ownership Status and Areas of Responsibility for the State of Utah SGID10.CADASTRE.LandOwnership *SITLA Layer File (STATE_LGD) Fields Highest level owner of parcel Agency level owner of parcel 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 OWNER codes Sample parcel attributes 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. Vertical Alignment “Nuisance” adjustments” = Integrated to PLSS Nov 2007 How the Data is Used Rock Wall Trespass Road Trespass Alignment Quality Control CadNSDI Lack of Confidence Boundaries Cadastral Control “Houston…” Deficiencies with PLSS Stewardship • Under-funded – Quality control issues – Too much downstream GIS data is being created using imprecise GCDB corner data as foundation • BLM not incorporating local survey control • Lack of input on ‘areas of interest’ for new surveys – Primary focus on BLM and Public Lands • Nuisance mathematical adjustments = moving targets • FGDC cadastral data model is a data transfer/exchange format, not suitable for direct use • Uncertain future commitment BLM is currently exploring using a GIS for their PLSS processes: Manipulation, Quality Control, etc… A new model…? • BLM stewards GCDB representation of state boundaries, gathers public land corners • State opts to maintain GCDB corner point and PLSS division layers – – – – MOU for contributing/supporting users, incl. BLM Creation of a single access point for tie sheets Local high precision control incorporated No more nuisance adjustments • GCDB and Public Land ownership layers maintained in a single database as an integrated ‘fabric’ in a GIS Follow up Jessica Kirby, [email protected] Bert Granberg, [email protected] Administrative Boundaries Shonin Anacker and Erin Fashoway Federal Agencies & Boundaries • National Boundary Group • U.S. Census Bureau (BOC): • • • • Boundary and Annexation Survey (BAS) Administrative Boundary Programs Cadastral Pilot Project Boundary Quality Assessment and Reconciliation Project (BQARP) 55 What is the Boundary and Annexation Survey (BAS)? • A voluntary survey of local, county, state, and tribal governments • Conducted annually to collect information about legal geographic areas • Primary source of information for: – Legal boundaries and boundary changes – Names, functional statuses, and types of governments – New governments – Dissolved governments – Higher-level geographic relationships • e.g. a place annexes into a new county 56 BQARP Scope States Counties Incorporated Places Minor Civil Divisions Title I School Districts (with approval of state Title I coordinator) • Public Lands • • • • • Incorporated Places • Legally bounded entities • Depending on the state, incorporated places may be called cities, boroughs, towns, and villages • For the 2010 Decennial Census there were 19,540 reported incorporated places 58 Popular Conception of Place: Local Conception vs Legal Boundaries 59 Minor Civil Divisions Public Lands: For Census Use Cass County, North Dakota – One Case Study Feature Type Percentage PLSS only 8% Parcel 42 % Road (Frontage) and PLSS coincident with Road 37 % Hydro 13 % The PLSS and Roads are often coincident which accounts for the low percentage of PLSS Only coincidence 62 Current TIGER Place Boundary Compared to Local Parcel Data Blue = Census Boundary for Great Falls Red = State of Montana Boundary for Great Falls Orange = Parcel Census clearly leaves out parcels that include Housing Units= population 63 Current TIGER Place Boundary Compared to PLSS Data Blue = Census Boundary for Big Water, UT Red = State of Utah Boundary for Big Water Purple = PLSS Census clearly leaves out parcels that include Housing Units= population Challenges Spatial Accuracy vs Currency BQARP Schedule Phase 1 (2014) Alaska Montana Utah District of Columbia Hawaii Phase 2 (2015) Washington North Dakota Maine Oregon New Jersey Nevada Indiana Virginia Kentucky Arizona New Mexico Minnesota North Carolina Arkansas Louisiana Florida Phase 3 (2016) Tennessee Idaho Wisconsin New York Wyoming Iowa Pennsylvania Connecticut California Ohio Colorado Kansas Delaware Maryland Alabama Georgia Phase 4 (2017) Michigan South Dakota New Hampshire Vermont Nebraska Massachusetts Illinois Rhode Island West Virginia Missouri Oklahoma Texas South Carolina Mississippi MT Administrative Boundaries Administrative Boundaries Administrative Boundaries are legally documented and attributed jurisdictional boundaries. These boundaries define the rights and interests on the land. Ensuring that boundaries, any boundary in the state of Montana, are correctly recorded and drawn is essential for several reasons Administrative Boundaries • Legal: Establishing well-defined, consistent boundaries minimizes legal irregularities. • Equitable collection/distribution of funds: Fees, taxes, or grants are associated with a defined area (e.g., fire district). • Equitable distribution of benefits: boundary lines define benefit areas (e.g., public water/sewer districts). • Mapping: Accurate boundary lines are used in creating paper maps, delivering online spatial-based services, and in public policy decision-making. • “Bad” geography: Many new districts rely on existing, erroneous district boundary lines, thus producing a domino effect of inaccurate information. • Public knowledge: Public information on district boundary legal descriptions and their corresponding maps should be correct and dependable.
