Geoinfo Techonology in Project Planning

Current applications in earth science and environmentalprojects need integration of:

inter-disciplinary dataset

multiple layers of information

spatially base in nature or map

wide range of scale and accuracy

Capability of spatial analysis is vital in providing technicalbackbone, decision making and dissemination in one platform

Sustainable Development

Geographic Information System (GIS) technology can helpestablish cross-sectoral communication

By providing very powerful tools for storage and analysisof multisectoral spatial and statistical data

Integrating geo-relational databases of different sectors

Package the information and result in a manner that easyfor users (information receivers) to understand, use andvisualise

GIS technology is well suited for integrated approach toplanning and management of sustainable development

GIS Applications in SD Project Planning

Geoinformation for information management:

Geological Heritage of Malaysia; and

Geohazard Mapping of the Klang Valley

Geoinformation for land planning:

Site investigation for land planning development; and

Guidelines for development in EnvironmentallySensitive Areas for highlands and mountains forSelangor

Geoinformation for integrated research:

Kundasang Landslide Complex: Hazard Assessment andControl; and

Langat Basin Ecosystem Health

Geological Heritage of Malaysia

Geological Heritage of Malaysia for Conservation and Sustainable Use

Geo-relational data of sites with geological significant inconservation geology to inventorise geological heritagessite and their descriptions

Geological diversity of Malaysia:unique minerals, rocks and structuresfossilsmagnificent geological-crafted landscapes


A national database for Malaysian geological heritage was set up to inventorise geosites:

recorded

characterised

valued

ranked

… accordingly to its importance in Earth’s history and aesthetic value


The information was stored in Microsoft Access to enable access, sorting and classification

Database was enhanced by the use of GIS

ESRI ArcView was used to display the location of each geosite

Langkawi Geosites

GIS maps (hotlink) to databasewith detailed information ofindividual geosites in the formof text, figure or picture

Having GIS to host the Malaysiangeological heritage easesconservation and land useplanning considerably

Geosites can be overlaid withexisting land use and planningmaps to formulate futureconservation strategies


User oriented information and result dissemination:

Web GIS Application or Mashup, distribute interactive geographical information on web

I.e: Geological Heritage Site in Google Earth for tourist to access

Intensive hazards (flood) and pervasive hazards (landslide, riverbank erosion and subsidence) are some aspects to be considered in physical planning

Mapping of the incidences of these geohazards and analysis of their characteristic, distribution, potential and risk


In mapping and assessment of geohazards, numerous data, consideration and models was used to ultimately derive multi-hazard and risk maps for regional planning

Integrated geoscience information is provided in the form of GIS layers for preparation of planning tools

Using the capability of the GIS interface for • terrain analysis, • geomorphologic data; and • geologic data

to provide scientific tools for geohazard management


Four groups of information are used to develop the geohazard database:

• basic geohazard inventory (flood, slope failure, riverbank erosion & subsidence)

• terrain analysis maps (topography, slope, drainage & geology)

• geohazard potential

• geohazard risk maps

The output was an assessment of the susceptibilityof physical environment in the form of:

Large Scale Active Landslides: The Distribution

Six large-scale active landslides, approximately one square kilometre each, have been identified.

These landslides are collectively called the ‘Kundasang Landslide Complex’.

Integrated Hazard ResearchKundasang Landslide Complex:Hazard Assessment and Control

GIS acts as a system to include:• digital elevation data• geological and structural geology mapping• landslide features and surface deformation• subsurface data• slope and groundwater monitoring data

GIS is also used for:• Hazard• Vulnerability• Risk Map• 3D Visulalisation

Integrated Basin-wide ResearchLangat Basin Ecosystem Health

To understand the status, trends and driving forcesaffecting ecosystem health in the Langat Basin:

• economics• sociology• biology• environmental chemistry• geology• human health• governance

into consideration ecology, environment, hazards,economic and social well-being was an example ofthe inter-disciplinary research that require ageoinfo system to host multi-facet dataset inecosystem health studies.

Major findings area:

• integration of primary and secondary data

• status, trends and driving forces

• databases and inventories of resources, state of pollution, habitat quality, human population dynamics, industry and quality of life

• sectoral ecosystem health indicators

• ecosystem scenario tool


Land Use 1974

Land Use 2001

The Quite Useful Ecosystem Scenario Tools (QUEST) has been jointlydeveloped between LESTARI and British Columbia University, Canada.

QUEST has been developed to cater for:

Capacity Building

Maximizing Use of Data

Facilitating Integrated and Strategic Thinking

Promoting Transparency

Accountability, and Participation

Information Dissemination and Education

Strengthening Inter-institutional Relationships


Langat Basin QUEST

GIS contributions can be seen from four aspects:

To develop a comprehensive and systematic database forplanning and development analysis

To determine development impacts and managementimplications

To determine trends and development impacts towardsecosystem health

To propose a holistic strategic planning tool for ecosystemmanagement


Concluding Remarks

Geoinfo Technology particularly Earth Science related informationhas been extensively used for Project Planning

More systematic and structured model/program is needed for theapplications in the integrated and holistic manner
