National Research Council Study Committee
3Project Scope
Building from the NRC's 1980 report "Need for a
Multipurpose Cadastre," This study will highlight
the status of land parcel databases in the United
States, provide a vision for the future, and
develop a strategy to complete this NSDI
Framework data layer..

6What 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
7Parcels are a critical part of a modern GIS

10Benefits 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
11Benefits
- 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
12What 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.
13What do we know ?
- The major obstacles
- organizational and institutional requirements.
14But, of course, we knew that in 1980
1980
15States 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
161980 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.
171980 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.
18What if recommendations had been followed ???

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

20Ben 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
21Synthesis 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
22Feedback from 400 respondents Not A Survey
23Extreme 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)
24Extreme 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

48What 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

62Redundant
- 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).
63Local Business Case
- About 920 counties have programs
- 98,000,000 parcels
- 70 parcels completed
64Cost Estimate Stage and von Meyer

65How Many Parcels are Available in the Parcel
Workforce
66Roseau 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.

CoalitionContests Zillow
Zillows over and under appraisals negatively
impact on consumers real estate and financial
transactions, and injures entire communities,
While the focus of the attached complaint is
upon all communities regardless of income, the
fair housing complaint will argue that Zillow
perpetuates the undervaluation of low-moderate
income communities in violation of the Federal
Fair Housing Act.

- 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.
90NSGIC 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.
