NOTES
The introduction to this unit describes the outline for
the next module.
Many of the issues outlined in this unit are illustrated
in a 20 minute video, GEOBASE - A Better Way, produced by and
available from the City of Newport Beach, California. The
video was originally intended for viewing by the City Council
and other city officials to show the progress and promise of
the GEOBASE system.
UNIT 60 - SYSTEM PLANNING OVERVIEW

University
A. INTRODUCTION
- in most cases, the design, purchase and implementation of
a GIS is a significant commitment in terms of personnel
time and money
- it is extremely important to understand the issues
involved in the development of GISs
- these issues will ultimately affect the efficiency
and value of the installed GIS
- it is possible to identify several stages in the
development of a GIS
- these can be characterized in several ways
- the following general outline serves as an
organizing framework for the next 6 units:
- development progresses through the following stages
- note that these are not necessarily sequential and
some may operate concurrently with others
1. Problem recognition and technological awareness
- a necessary beginning point
2. Developing management support
- critical to the initiation and success of the
project
3. Project definition
- includes identifying the current role of spatial
information in the organization, the potential for
GIS, determining needs and products, writing the
proposal
4. System evaluation
- includes reviewing hardware and software options,
conducting benchmark tests, pilot studies and cost
benefit analysis
5. System implementation
- includes completion of a strategic plan, system
development and startup, design and creation of the
database, securing on-going financial and political
support
- this unit looks at the two least formal and unstructured
initial stages: needs awareness and building management
support
B. PROBLEM RECOGNITION/TECHNOLOGICAL AWARENESS
- in order for an organization to become interested in
acquiring a GIS, someone or some group within the
organization:
1. must perceive that the methods by which they
are currently storing, retrieving and using
information are creating problems
2. must be aware of the capabilities of GIS
technology
Problem recognition
- Aronoff (1989) suggests six problems that prompt GIS
interest
1. spatial information is out of date or of poor
quality
- e.g. often land information documents (maps and
lists) are seriously outdated and questions
regarding the current situation cannot be answered
without digging through a stack of "updates" since
the last major revisions
2. spatial data is not stored in standard formats
- e.g. a city's parcel maps will often vary in quality
from one area to another
- one area may have been "flown" and mapped using
aerial photography at 1:1000 scale some years
ago, but updated by hand drafting
- other areas may have been mapped by
photographically enlarging 1:24,000 topographic
maps, or city street maps of unknown quality,
and hand drafting parcel boundaries
- maps may have been reproduced by methods which
introduce significant errors, e.g. photocopy
3. several departments collect and manage similar
spatial data
- this may result in different forms of
representation, redundancies and related
inefficiencies in the collection and management of
the data
4. data is not shared due to confidentiality and legal
concerns
5. analysis and output capabilities are inadequate
6. new demands are made on the organization that cannot
be met within the data and technological systems
currently available.
Technological awareness
- sometimes the "problem" is simply an awareness of newer
technologies that offer a "better way"
- King and Kraemer (1985, p.5) distinguish between supply-
push and demand-pull factors in leading to awareness and
the eventual acquisition of computing technology
Supply-push factors
- changes in technological infrastructure
- improvements in technological capability
- in GIS: improved hardware, software,
peripherals; better access to existing digital
datasets, e.g. TIGER files
- declining price-performance ratios
- in GIS: impact of introduction of 286- and
386-based PCs, workstations, reduction in cost
of mainframes and minis
- improved packaging of technical components to
perform useful tasks
- in GIS: better (more friendly, more versatile)
user interfaces, better applications software
- concerted marketing efforts of suppliers
- advertising creates an aura of necessity
- in GIS: hard not to go with the current trend,
in spite of the fact that GIS advertising is
probably low-key relative to other areas of EDP
- direct contact of salespeople with potential buyers
- in GIS: demonstrations at trade shows,
presentations at conferences by vendors
- long-term strategies of technology suppliers
- selective phase-outs - vendor drops support of
existing system to encourage new investment
- price reductions or outright donations to
universities to raise students' familiarity with
product
- low-cost or cost-free pilot studies offered by
vendors at potential customer's site
- interchange - at present, there are high costs to
conversion from one GIS vendor's system to another's
- customers are "locked in"
Demand-pull factors
- endemic demand for accomplishing routine tasks
- need for faster and more accurate data handling in
report generation, queries, map production, analysis
- society's appetite for information is unlimited
- in GIS, there is no upper limit to need for spatial
data for decision-making
- there is no totally satisfactory minimum level
of accuracy for data
- more accurate data always means better
decisions
- institutionalized demand
- "keeping current" with technology
- maintaining systems on which the organization has
become dependent
- affective demand
- perceived need among organizational actors to
exploit the political, entertainment and other
potentials of the technology
- in GIS: GIS technology is impressive in itself -
high quality, color map output, 3D displays, scene
generation - GIS output may be perceived to have
greater credibility than hand-drawn products
Collecting information on GIS
- once the need for GIS is recognized, an individual or
group may begin gathering information on GIS in order to
develop a management proposal
- information will need to be collected on:
- the status of existing GIS projects
- the direction the GIS industry is moving
- the potential applications of GIS in the
organization
- sources of information include:
- personnel within the company
- "missionaries" or GIS proponents may have
familiarity through educational background,
external contacts
- industry consultants, system vendors, conversion
service companies will be very willing to provide
information
- industry organizations such as AM/FM International
or American Congress on Surveying and Mapping (ACSM)
are excellent sources
- a growing number of newsletters and magazines are
being marketed within the GIS industry
- a useful mechanism is a Request for Information (RFI)
- sent by the company to all known vendors of GIS
software
- should ask for:
- general company information
- system capabilities
- hardware and software requirements
- customer references
- general functional capabilities
- example applications
- customer support - training and maintenance
programs
- general pricing information
- site visits to operating GIS projects are useful
- can observe the daily operations of the project
- gain insight from project personnel about system
performance and support
Project plan
- after consulting with industry experts, visiting other
sites, considering corporate objectives, the first level
of project definition and planning can occur
- project plan should be dynamic, adaptable, refined
as better information becomes available
- plans will be very general, broad-brush at this
stage - a general description of the desire to
investigate systems further and a plan for
proceeding
- for those charged with developing a project plan, it is
important to discover who or what is the force behind the
interest in GIS
- the individuals involved and the significance of the
problem are important in determining how to proceed
with selling the idea to the organization
C. DEVELOPING MANAGEMENT SUPPORT
- once the need has been identified it is critical to gain
support of the decision-makers who will be required to
commit support in the way of funding and staff
- decision-makers need to be assured that the project will
be developed and managed in a sound manner
- management will need to know:
1. what GIS is and what it can do for the
organization
2. what the costs and benefits of the system will
be
- a carefully managed development project is critical
Example - AM/FM Project Life Cycle
Administration of the project
- with initial support assured, the project requires strong
leadership to implement the system
- quite often, the agency realizes that their own people do
not possess the expertise nor have the time to fully
explore and evaluate the alternatives
- in this case, an outside consultant may be brought
in to assist in a "needs assessment"
- the GIS consulting industry is growing rapidly, and
now involves several of the "big 8" major
international management consultancies
D. NEWPORT BEACH GIS PROJECT
- Newport Beach, California developed one of the early
successful urban GISs
- the following section reviews the initiation and
development of their GEOBASE project
- this provides a general introduction to the process
of GIS system development
Needs awareness
- interest in Geographic Information Systems for multi-
purpose cadastral applications arose at about the same
time in several major departments of the city
- data processing professionals were exposed to the
technology at trade shows
- the Utility Department saw innovations in AM/FM at
the major utility companies and some larger
municipalities
- city planners were exposed to GIS by attending
professional meetings
- these and other departments were becoming aware of these
newer technologies being successfully implemented in
other cities
- with a core of interested individuals, an informal
committee was formed to study GIS and see what it could
do for them
Management support
- to gain administrative support for a LIS, the GEOBASE
Committee set about educating the major departments
within the city about the benefits of GIS and recruiting
their support
- this included Data Processing (Finance), Utilities,
Planning, Building and Safety, Public Works
(Engineering), Fire, Police, and even the Library
- a series of units and demonstrations were set up to
inform departmental personnel of the proposed
project
- the result of these efforts was a proposal to the City
Council and City Manager for funding for an integrated
Land Information System
- this proposal had the endorsement of all the
departments mentioned above
- the GEOBASE project was approved
Administration of the project
- in Newport Beach, a GEOBASE Steering Committee, comprised
of representatives from five departments (Utilities,
Planning, Data Processing, Building, and Fire) was
established to guide the project's implementation phases
Establishing the automation priorities
Pilot projects
- in the GEOBASE project, two major pilot projects were
undertaken during the first year of operation
- one took a portion of the city and converted the parcel
and infrastructure data as a "Prototype" for the eventual
city-wide basemap
- this project was useful to determine the best ways
of entering the cadastral information (scanning
versus digitizing versus coordinate geometry) and
for establishing the ground control and accuracy
standards for the database
- the second project involved digitizing the entire city,
block-by-block, from a smaller-scale basemap to be used
to revise the City's General Plan
- in this project, valuable skills were gained in map
production, establishing symbolization standards for
City maps, and dealing with attribute databases
- both projects produced useful and highly "visible"
results

EXAM AND DISCUSSION QUESTIONS
1. There are over 3000 counties in the US, each with their
own needs for LIS and multipurpose cadaster. What factors
would you expect to influence the priorities and plans of
each county in this area? Design a questionnaire survey
that could be used to verify your answer.
2. Compare the circumstances in Newport Beach to those in
your local area. Are they similar? How does the state of
LIS development in your area differ?
