Business Case

• Internal Agency Operations
• Agency Data Share Government to Government
• Agency Customers Service Providers
• Web Publish Public and Other Users

3
Internal Agency Operations

• Automate Parcel Data inside the agency
• Use the result inside the agency only
• Focus the attributes, products, reports and
  requirements on existing agency needs
• Metadata internal and informal

Benefits
The gains from new technology can be categorized
into three types increases in efficiency, so
that the same task can be performed with fewer,
often significantly fewer, resources increases
in effectiveness, so that the same task can be
performed with greater accuracy and fewer
mistakes new products and services, which
could not have been produced without this new
technology.
16
Benefits
The gains can be achieved by various routes
reductions in processing costs reductions in
search costs more effective scheduling, and
therefore reductions in waste reductions in
uncertainty, and therefore more effective service
delivery better matching of products and
services to needs as a result of better
information.
17
Benefits - Returns

• Produce maps
• Check assessment and tax rolls
• Support permitting
• Geocoding address files
• Decrease in repetitive tasks
• Elimination of redundant tasks
• Decreased travel and field visits
• Decreased mistakes as a result of increased
  accuracy of information
• Increased efficiency and time savings from new
  services and capabilities.

New York City Strategic Plan
City Infrastructure - Strategic IT Business
Initiatives
Property Share The City has recognized that rapid
access to accurate property information can
improve a range of services that the City
delivers. Property Share is a concept under
consideration that will leverage the Citys
geographic data architecture to improve the
quality of property-related information (such as
address, ownership and zoning). This information,
combined with access to source data, will improve
emergency response and public safety, facilitate
more accurate and faster issuance of permits, and
increase owner accountability for compliance with
building and environmental laws.
21
New York City Strategic Plan
Foundational Information Technology
Geographic Data Architecture The Geographic Data
Architecture initiative will provide the City
with a common repository containing a single,
unified street and address inventory for all City
agencies that use geo-coded information. This
initiative will establish a Citywide Geographic
Information System and Geofile platform that will
support collection and dissemination of accurate
geographic data. This will contribute to improved
emergency response capabilities, more-accurate
billing and collection, and will enable the City
to better track development and construction
activities throughout the City.
22
Land parcels are the foundation for many aspects
of public and community life. This report
presents the findings of a reconnaissance study
of information about land parcels in New York
State. Broadly defined, this information includes
data about parcels that describe their nature,
location, use, and association with physical and
political geography. The purpose of the study,
sponsored by the New York State Office of Real
Property Services, was to provide information to
help shape strategies for broader understanding
and more effective use of parcel data in New York
State.
23
The Value of Parcel Data
Judging from the variety and importance of the
foregoing uses, the value of parcel data appears
to be immeasurable. Every organization we
interviewed regarded parcel data as a crucial
resource. Nearly all of the interviewees
indicated that without parcel data, their work
would either be greatly hindered or not possible
at all. Parcel data is integral to the missions
of many different organizations and many
different functions within them. The value of
parcel data, in terms of mission-oriented
benefits, can be seen in everything from smart
growth to public safety. However, because parcel
data use is so deeply embedded in these various
functions and programs, it is difficult to
quantify its direct economic value.
24
Agency Data Share Government to Government

• Share the internal agency parcels and attributes
  with other government agencies.
• Develop exporting reports that standardize the
  data content to a publication format.
• Metadata more formalized
• Provide on request

25
Easements
The easement feature class will reduce the amount
of time currently spent by personnel looking at
hardcopy and digital tax parcel maps to research
ownership and easement locations. The types of
research that will see benefits from the
development of this feature class include
Locate existing easements for new construction
projects and investigating customer complaints to
determine if the County is responsible for a
problem. Storm drain easements location. New
projects, such as streetscapes. Police
Department can use the layer to settle civil
disputes.
26
Easements Benefits and Costs
27
Agency Owned Lands
The County-Owned Property layer will save time
spent researching material to find out
information about a property, including the
location, ownership, and responsible agency. This
would also reduce an agencys dependency on PDM
providing this information, since the data could
be hosted by the Enterprise. Each of these
benefits would help reduce the turnaround time
for a request. As an added benefit, the
development of this layer would help to identify
small parcels that are not easily readable on the
State Tax Maps and would result in an increased
quality and accuracy of the Tax Parcel layer.
28
Rights of Ways
This dataset consists of a point dataset that
shows the location of ROW features held by the
County, as well as a polygon feature class that
shows the boundaries of these features. This
dataset holds a strong topological relationship
with the cadastral database, since the boundaries
of these features are generally shared with
parcel and easement boundaries.

• Same data set as the Agency data share
• Distribute upon request a standard publication

• Provide to support contractors and service

Digital Plat Submission
37
Digital Plat Submission
The following qualitative benefits could be
realized as a result of implementing the digital
plans submission Save time and money spent
converting these datasets. Developers would not
have to travel to the office to submit plans.
Save time and money spent accepting digital
plans, since information would be already
available from the database. Distribution of
plans would be easier with no hard copy
duplication. Acceptance of plans would be
easier, since the database could track the review
process within the database.

State of Montana Cadastral Mapping Project
The goals are to produce and maintain cadastral
information in a consistent digital format for
the entire State. Their system integrates two
databases of the Montana Department of Revenue
Computer Assisted Mass Appraisal System (CAMA)
database and the U.S. Bureau of Land Management
Geographic Coordinate Data Base (GCDB).

• Well locations
• Horizontal well paths
• Field, unit, and CBM project boundaries
• Well spacing units
• Pending applications for hearing

43
Benefits

• GIS polygon data can be created directly from the
  MBOGC database using standard legal descriptions.
• Tract descriptions are entered and edited in the
  Boards database no digitizing or GIS product
  to independently maintain.
• Utilization of the GCDB data has allowed creation
  of additional datasets and tools which have
  resulted in improved efficiency during a time of
  increasing workload.

Findings

• Parcel data provides intelligence providing
  information about
• land ownership,
• property values,
• structures, and
• land use.

Where was this and who owns that spot of sand?
46
Findings

• 2) Integration of parcel data with other data
  sets and land characteristics provides a rich and
  stable data source.
