Introduction
Kementerian Wilayah
Persekutuan (KWP) or The Ministry of Federal Territory has
moved from property-based GIS to Regional-based applications. Eight
applications
have been
developed
to respond to critical
regional development issues. Ability to frame the right regional questions
and its subsets at the early stage of GIS development could substantially
reduce additional programming time. Past GIS training had
failed to focus on substantive analytical spatial analysis (statistical
and mathematical
modeling) relevant to urban and regional planning issues. Greater
efforts should be given to multiple stakeholder discussions to improve
quality of
data and analysis. In addition, KWP has embarked on developing
a regional planning support system (RPSS) focusing on scenario building,
measuring
development impact and tracking module to monitor and measure regional
plan targets (including structure plans).
Klang Valley Region
A
Brief History
AGISwlk grew from a pilot project initiated in 1995 covering a 4.5-kilometer
strip in the heart of Kuala Lumpur. The goal of the phase is to demonstrate
GIS capability as a planning decision support tool. The second phase
covered Kuala Lumpur CBD and focuses on data collection, storing, and
presentation. Experiences
obtained during the first two phases were used in a more ambitious third
phase of GIS development in Klang Valley. The third phase covered the
entire Federal
Territory of Kuala Lumpur. Six applications module were developed by
extensive analysis of cartographic layers as well as attribute data.
These application
modules were covered under threat, built-up area, squatters area, green
area, pollution level and public utilities. The fourth phase is the
present AGISwlk.
It covers the entire Klang Valley Region consists of 5 districts and
8 local authorities. Eleven applications were developed: physical, built-up
areas, green
areas, tourism, environmental quality, geohazard, industrial and commercial,
low-cost housing and squatters, public amenities, utilities, and transportation.

GIS
Database For Regional Planning Analysis
The database for the Application of GIS for Klang Valley Region (AGISwlk) was
designed and developed to support ten application modules namely built up area,
green and recreational areas, traffic and urban transport, squatter and low-cost
housing, environment, utilities and community services, industrial and commercial
development, population and socio-economic, tourism facilities and geohazard.
This required more than 100 map layers including base map, administrative
boundaries, physical characteristics, environmental quality, traffic and urban
transports, green and recreational areas, public facilities and utilities.
The database development for Klang Valley
region basically involve gathering of data, spatial and attribute data entry,
and generating of data layers based on the described applications for analyses
purposes. Paper maps and remotely sensed data including satellite data and
high-resolution digital orthophotographs are major sources for collecting digital
data. Data gathering was carried out based on the type of data needed and sources
of data. Data entry was then done through interpretation of the data gathered
into the required form using the ArcGIS software.
Since the geographic information is stored
in its primary form, analysis can be more quantitative and rational. The modeling
stage which is called planning process, require planner to make
explicit explicit for the selection of alternative programs. This is to encourage
the selection of objective criteria, based on real data for the study area. Analyses generated by AGISwlk employs the multi-criteria and multi-objective
approach which integrate all possible relevant elements.
What's
Next
AGISwlk is shifting from development phase to system improvement and maintenance.
Additional and more specific analysis will be carried out under each of the
existing 8 application modules. Two new applications, tourism and geohazard,
are being developed. Special attention is also given to the spatial aspect
of housing supply and demand. This is to ensure that housing issues are not
only tackled from quantity and quality perspectives but also meet spatial requirements.
The new application modules and additional analyses are expected to widen the
coverage of planning and development issues relevant to operating agencies.
This will enhance AGISwlk capability as decision support tool for effective
planning and management in the most vibrant and productive region in Malaysia.
An integrated application module called Integrated Landuse Assessment (ILA)
model is being developed. There will be two sub-modules under ILA. The first sub-module is to identify
the best site for development after taking into account economic, social, and
environmental interests. The second sub-module is designed to have the capability
of assessing the impact of proposed development in the region. Upon identifying
the location of a proposed development and its main features such as floor
space, population density, expected traffic generation, and number of school-going
population, ILA will assess the impact of the proposed development on the
level of services in the area. Assessments provided by ILA will be useful
for local authorities in determining the suitability of the site for development.
The information will also highlight the extent and type of constraints the
particular area will face and thus allow preventive measures to be carried
out or properly planned.
Regional Planning Support System (RPSS) is another
GIS-based application module currently being developed. It is developed in
conjunction with the preparation of the Klang Valley Perspective Plan II
2000-2020. It performs three major tasks: to generate desirable development scenarios
in the region, to monitor implementation of development plans and to assess development
impact on the region. RPSS is expected to complement spatial analysis
covered by AGISwlk.
