What do we know ?
  • There is a critical need for a better
    land-information system in the United States to
    improve
  • land-conveyance procedures,
  • furnish a basis for equitable taxation
  • provide much-need information for resource
    management and environmental planning

7
Parcels are a critical part of a modern GIS

Benefits From Parcel Data
  • Potential Benefits to Local Government
  • Assures that the best available data are used in
    each public transaction
  • Avoids conflicts among land records of different
    public offices
  • Improves accuracy of real-property assessments
  • Provides base maps for local planning and
    preliminary engineering studies
  • Provides a standardized data base for
    neighborhood, municipal, county. or regional
    development plans
  • Avoids costs of maintaining separate map systems
    and land data files
  • Encourages coordination among separate map
    systems and land data files
  • Improves public attitudes toward administration
    of local government programs
  • Potential Benefits to state governments.
  • Provides accurate inventories of natural assets
  • Provides accurate locational references for
    administration of state regulations such as
    pollution controls
  • Accurately locate state ownership of other
    interest in land
  • Provides a standardize data base for management
    of public lands
  • Provides large-scale base maps for siting studies
  • Simplifies coordination among stat and local
    offices
  • Potential benefits to the federal government

11
Benefits
  • Potential Benefits to Private Firms
  • Provides faster access to records affecting
    individual rights, especially land title
  • Clarifies the boundaries of area restricted by
    zoning wetlands restrictions and pollution
    controls or other use controls
  • Produces accurate maps that can be used for
    resolving private interests in the land
  • Reduces costs of public utilities by replacing
    present duplicative base mapping programs
  • Improves efficiently of tax supported government
    services as describes earlier in this table
  • Potential Benefits to Individuals
  • Provides faster access to records affecting
    individual rights, especially land title
  • Clarifies the boundaries of areas restricted by
    zoning, wetland restrictions, pollution controls,
    or other user controls
  • Produces accurate maps that can be used for
    resolving private interests in the land
  • Reduces cost of public utilities by replacing
    present duplicative base-mapping programs
  • Improves efficiency of tax supported government
    services as described earlier in this table

12
What do we know?
  • Current technology is adequate in most cases for
    the surveying, mapping, data collecting, filing
    and dissemination of information.
  • Advancement in computer applications,
    communication networks and copying processes
    promise of more-efficient use of the multipurpose
    cadastre.

13
What do we know ?
  • The major obstacles
  • organizational and institutional requirements.

14
But, of course, we knew that in 1980
1980
15
States Role
  • That each state authorize an Office of Land
    Information Systems, through legislation where
    necessary, to implement the multipurpose cadastre
  • That states enact legislation to ensure the
    compatibility of county and local records
  • Promoting effective, efficient and compatible LIS
    among governmental levels in cooperation with the
    federal government to ensure compatibility on a
    national basis
  • Setting Standards for state, regional and local
    government surveying, mapping and land data
    collection making use of federal technical
    studies

16
1980 Recommendations
  • While the federal role was to coordinate and fund
    the program they clearly recognized that the
    actual data collection must come from the bottom
    up at a series of county level Offices of Land
    Information Systems.
  • We recommend that local governments be the
    primary access point for local land information
  • That local governments maintain and data
    compatible with a multipurpose cadastre and
    transmit these data to high levels of government
    when needed.

17
1980 Recommendations
  • that federal legislation be prepared to
    authorize and fund a program to support the
    creation of a multipurpose cadastre in all parts
    of the Nation
  • that the Office of Management and Budget
    designate a lead agency for the multipurpose
    cadastre.

18
What if recommendations had been followed ???
  • Savings
  • Tax payer
  • Effort
  • Better land use
  • Cheaper property transactions
  • Insurance premiums
  • Appraisals
  • Lives
  • How would we be conducting the 2010 Census?

Summit - Land Parcel Databases A National
Vision Sponsored by The National Research
Council Committee on Land Parcel Databases A
National Vision
  • GOAL
  • To assemble stakeholders who have a major
    interest in the management and use of land
    records in order to obtain input on
  • How different organizations would benefit from
    national land parcel data
  • Strategies for developing, coordinating, and
    maintaining national land parcel data
  • FORMAT Three panel discussion sessions
  • 900-930 Introduction
  • 930-1130 Session 1 Federal Agencies
  • 1230-230 Session 2 Private
    Sector-Property Interests
  • 300- 500 Session 3 Professional
    Organizations

Ben Clark, Zillow
  • Zillow We are Just a media company - Goal to
    attract eyeballs to web site
  • Also interested in helping Arkansas complete
    parcels
  • Difficult to justify the most rural areas

21
Synthesis of Stakeholder Feedback
  • The committee appreciates the input
  • Findings will become part of the study and a
    manuscript
  • More than 400 responses
  • Thousands of comments
  • Wide range of stakeholders
  • In the trenches local, state, federal and
    private sector
  • Managers
  • Elected officials
  • Producers
  • Consumers
  • Very opinionated
  • Passionate about parcels

22
Feedback from 400 respondents Not A Survey
23
Extreme Positive
  • Currently municipalities and counties with
    17th-century land records systems are
    systematically crippled in their ability to
    administer taxation equitably, conserve their
    natural resources, plan for rational growth, and
    educate their students in geospatial
    technologies.
  • It's really amazing that there are no digital
    parcel maps readily available in large areas of
    the country. This is the 21st century,
    Hello????? (Donald Cooke, GDT Founder, TeleAtlas
    North America)

24
Extreme Negative
  • I think this is primarily a 'sales job' by
    individuals who stand to personally gain from a
    national cadastre. Because of the volume of
    change taking place in many areas of the Country,
    a national database would be consistently
    out-of-date and lead to decisions based on
    incorrect information. The value to this County
    would be minimal. Now, if some funding were
    attached to participation in a national effort,
    to help maintain the information, then I could
    see a benefit at the local level. (Richard
    Hanning, GIS Manager, Greenville County
    Government, SC)

What benefits do you perceive from having a
national multipurpose cadastre?
  • Parcel data is the fundamental building block
    for all geographic analysis and serves as the raw
    material for most applications most geographic
    analysis is benefit from the ability to
    understand the result at the parcel level
  • A multipurpose cadastre enables a vast range of
    location-based services that will improve safety
    and increase efficiency of current operations
  • Available, critical data for emergency response
  • Local parcel data were still being sought 8
    weeks into the response to Hurricane Katrina
  • Impact from most disasters is best understood at
    the parcel level
  • GIS is becoming the way disasters are managed. A
    common operating picture depends on an available
    multipurpose cadastre
  • National response centers such as IMAAC depend
    on the availability of local data for accurate
    hazard predictions and health recommendations
    such as shelter in place
  • Most DHS programs depend on geographic data
    that is at the parcel scale - for example
    Critical Infrastructure Program
  • The ability to protect the privacy of individuals
    is dependent on an accurate parcel-level database

What Do Parcels Cost?
  • Wake County - Free via FTP
  • Mecklenburg County 250
  • Los Angles 2006 100,000
  • 2007 Free
  • Santa Clara CA 250,000

62
Redundant
  • For example, within King County WA, even though
    there is county wide parcel program 10-15 cities
    are independently engaged in parcel mapping to
    varying levels of skill and sophistication.
    (George Horning King County WA GIS URISA,
    2006).

63
Local Business Case
  • About 920 counties have programs
  • 98,000,000 parcels
  • 70 parcels completed

Roseau County, MN 14,000 Parcels, 16,000 people
and 200,000
  • The need was very evident but it was hard to find
    funding in a county budget stressed by state
    cutbacks and increased services.
  • The difference that made Roseau Countys GIS a
    success is the persistence of staff and the
    progressive attitude and support of the Roseau
    County Board of Commissioners.
  • All section corners in the county with a GPS unit
    borrowed from the Greenbush School District. The
    GPS unit was acquired by the school district as
    the result of a science project grant.

  • standardized parcel level geography and
    normalized core attributes linked to the parcel
    id
  • support HUDs long-term planning efforts and
    will provide a data model for similar
    hazard-based projects on a national level
  • complete and make publicly accessible a
    spatially enabled parcel data layer that can be
    used to support HUDs long-term planning for
    hurricane affected areas in the Gulf region
  • the data structure enables the ability to
    migrate to a standardized national parcel layer
    and the geo-services as envisioned by the Federal
    Geographic Data Committee.

NSGIC 50 States Initiative
Fundamental change in the way all governments
will work together in the future to build the
National Spatial Data Infrastructure (NSDI).
Instead of the current build it and they will
come philosophy that relies on random grants and
partnerships, A new program emphasizing
strategic and business planning with specifically
targeted implementation grants, performance
measures and incentives will be employed.
