Geoinformation Science in Transforming Education and Research for Sustainable Tomorrow and ‘the
Bottom Billions’
Background
• Well-known that GIS is useful to many
organizations for various routine, tactical &
strategic decision making process.
• But still many organizations do not yet
implement/use GIS for various reasons.
• One major reason – cost
– Can we start GIS project with little or no cost?
GIS 101
COMPONENTS OF GIS
• Not just a technology - an integration of five basic components
provides functions and tools to store, analyze,
and display geographic information.
Software
Data
Hardware
integration of spatial
data and tabular data
(attributes)
computer system
on which a GIS
operates
Methods
People
GIS specialists vs
end users
Source: ESRI
A successful GIS
operates according
to a well-designed
implementation plan
and business rules
GIS COMPONENT (1)
• hardware
– computers to run software
– other related software
• software
– computer program to process data
• custom-written software
• generic programs are more popular
• data
– processed for information retrieval
– most costly compared with hardware and software
– longer life span
– at times, have legal value
GIS COMPONENT (2)
• People/Institution
– individual and organisation that uses or
implements GIS
– critical components - decides the success of
implementation
• need for GIS professional to analyze,
research, design complex GIS systems
• difficult to change humans to adapt with new
technology
– always overlooked
GIS Software functions
Capture
Analyze
Store
Display
Query
Output
GIS SOFTWARE SUBSYSTEM (1)
• data acquisition
– define, entry and preliminary processing data
– digitizer, scanner, survey equipment, etc.
• data management
– control existence, update, recall and deletion of
data
– database management system
GIS SOFTWARE SUBSYSTEM(2)
• analysis of data
– generation of information from data archives
– spatial analysis software
– value of GIS depends on the analytic functions it
provides
• information output
– generated information conveyed to the users
– information managed by computers can be
plotted, printed or exported into other systems.
A Quick look at the cost of GIS
implementation
Some strategies how to implement
gis with little or no cost
• Use freely or opensource softwares – many
available of many kinds
• Use insider talents not money – use talents of
existing staff
• Exchange data with other organisations
• Barter trade – offset cost of data capture with
other equivalent values
– E.g. give resell right to data (at agreed time period)
• Rent instead of purchase
• Provide incentive to staffs – extra leave or
sponsor to family day
Some strategies how to implement
gis with little or no cost…2
• Sell ads space in newsletter to generate
income to cover cost of GIS implementation –
newsletter related to GIS.
• Setup membership site – let say sharing
experience & giving support using opensource
GIS
– Just imagine if you charge RM20/month & have 500
members, total income RM10,000 per month (make
money while you sleep).

or no cost
What is Open Source and How
Does it Work
 Freely available software and source code with limited licensing
restrictions on distribution
 Collaborative, community-based software development process
 Proactively engages software users with software developers
 The Internet provides the backbone for a virtual software
development team
Tpyes of OpenSource GIS
• Software Development
– Desk-top
– Web-based (mapserver)
– Libraries
• Development team
– Individual-based
– Collaborative networks
– Corporation based
Why Opensource GIS?
• The Future of GIS – GIS for ALL & SpatiallyEnabled Society
Why Increasing Interests in OS GIS
(Benefits of the Open Source Model)
 Lower Software Cost - No licensing fees
 Resources are allocated to building applications and enhancing software, not
licensing multiple machines
•
•
Independence from proprietary technology
Security – risks especially sensitive applications such as e-government,
e-procurement
•
Enables development of highly customized applications based on
organisation’s needs – greater control
 Development priorities are driven by end-user needs
 Issues can be resolved in-house
 Vibrant user community – include corporate support
 Standards support – Open GIS Consortium
 Software quality - improved

GIS for Lembah Bujang
Archeological study
• Use GoogleMap & MapServer – for easy access
– Locational data using GPS.
GIS for Secondary
School
• Use MapServer (web-based) & Open Jump
(desktop)
– Case study Form 1 Geography Subject
The uses of OpenJUMP in teaching geography subject to Form 1 students.
Web-based tourist
information system
• Use MapServer – to find shortest distance from
origin to various tourist destinations

• Task
– Find a suitable site for a new university aquaculture
lab using the following selection criteria:
• Preferred land use is brushland (i.e. locode = 300 in
landuse.shp)
• Choose soil types suitable for development (i.e. suit >=
2 in soils.shp)
• Site must be within 300 meters of sewer lines
– Calculate the total area of the suitable site(s).

The Future for Open Source
Technologies
 More accessible Internet
 Adoption of open standards
 Tighter integration among open source technologies
 More demanding applications
 Rapidly maturing and growing user and developer
communities
Summary & Conclusion
• It is possible to start GIS project with little or
no cost if there is willingness to try & change in
mindset.
• One possible approach is to use Opensource
GIS software to minimize software licensing
cost.
• Most OS GIS softwares provide at least the
basic GIS functions – data capture,
management, manipulation, analysis & display
– sufficient to start using GIS – especially for
data input.
Summary & Conclusion
• Increasing availability of Open source GIS will
enable new users to start using GIS for free or
low-cost – suitable for developing countries
– In long-run all interested parties will have access to
GIS and able to optimise the use of digital data –
create spatially-enabled society.
