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

Software

provides functions and tools to store, analyze, and display geographic information.

Data

integration of spatial data and tabular data

(attributes)

Methods

A successful GIS operates according to a well-designed

implementation plan and business rules

People

GIS specialists vs end users

Hardware

computer system on which a GIS

operates

Source: ESRI

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

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).

How to implement gis with little

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 & Spatially-

Enabled 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

Thank you for listeningExample Projects

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.
