As we scurry through the first half of 2005 there were many headline news; some
good but mostly bad (ever wonder what has gone wrong?). A most encouraging piece
of news is the Prime Ministers approval of the 5-day working week and the reinstatement of the cost of living allowance (COLA). For me, the 5-day working week is a
dream comes true, as I have always been looking forward to that which our friends in
the private sector have long been enjoying. A 2-day weekend would definitely help in
reinvigorating the weary mind, and improve family-tie. The reinstatement of COLA is
also a shot in the arm especially for us living in cities like Kuala Lumpur, where ends
are usually hard to meet.
The 56th conference of the National Spatial Data and Mapping Committee (JPDSN), which was successfully held in Penang from 14-15 March 2005, had in principle agreed to the departments proposal of a
new 1:50,000 topographic map specifications. There were various reasons that led to the introduction of
the new map specifications. The key of which being the effectuation of the Malaysian Geocentric Datum
(GDM2000) that has resulted in a new map series and map sheets numbering system. Coupled with the
move by the department towards a 4-colour process printing, the new specification is absolutely necessary. Presently, efforts are being directed at completing the specifications for the rest of the map series.
In tandem with the new map specifications, the department is currently also in the process of drafting a
new digital map specification for its topographic database. This is a classical case of technological
advancement out-pacing tedious documentation. The national topographic database was created since
mid-1980s, without its specification until now. However, it is better late than never. This digital map
specification is expected to be completed by early 2006. With it, and the ever increasing number of
applications requiring digital map, perhaps it is time for us to bid sayonara to printed map and usher in
the digital map era.
Towards this end, it would be timely to mention that the infrastructure for the dissemination of digital
spatial data is now in place. The Geospatial Information Dissemination Centre System (SPPMG) which
is expected to be fully operational by early 2006 will facilitate the dissemination of spatial data to GIS
users nationally and internationally.
At the recently concluded meeting of the National Geographical Name Committee (JKNG) held in Kota
Kinabalu, the Guidelines for the Determination of Geographical Names were finalised. The Committee
has agreed for the document to be translated into English and also to be published as a Malaysian
Standard (MS) document. It is hope that this document together with the geographical names database
or the so-called Gazetteer will facilitate the creation of GIS systems and widen the usage of GIS-compliant databases.
In another note, the department has recently been tasked with the responsibility of creating a new
service scheme for GIS graduates. At present, the government do not have any specific service scheme
for GIS and geo-information science graduates. As such they cannot be employed in any government
services. A paper for this purpose has been prepared and presented to the Public Services Department
for its consideration. The approval of this new service scheme by the Government will undoubtedly
vitalise the GIS industry within the country.
Thank you.

Abstract
The integration of GIS and spatial dynamic models such as cellular automata has proven a useful tool
for modelling the dynamic spatial pattern of urban development. However, the validation of the result has
often been taken for granted. Usually, its validation was conducted by making a relative comparison
between the simulated and the actual spatial pattern of urban growth. Once the model produced the
simulated spatial pattern of urban growth that looked like actual areas, the model was terminated. This
form of validation may reproduce the spatial pattern of urban growth that looks like actual urban area; it
does not represent the accuracy of the actual urban locations. This paper demonstrates the application
of a GIS-based CA model developed for the Seberang Perai region, Penang State, Malaysia. This
model was developed using land use 1974 data and validated using land use 1981, 1990 and 1998
data. It was validated not only on the basis on its ability to reproduce actual urban areas but also the
morphology of urban boundary. Although the overall result is quite satisfactory with accuracy exceeding
70%, the model performed quite poorly when the area experienced an anisotropic type of growth or noncontiguous growth.
Keywords: Geographic Information Systems, Cellular Automata, Multi-Criteria Evaluation.

INTRODUCTION
Rapid urban growth especially in many developing nations in the last 20 years has created many urban
challenges to planners and urban managers (Devas and Rakodi, 1993; Drakakis-Smith, 2000). Thus,
various methods and approaches have been devised to help in managing and planning urban spatial
growth. Many studies have demonstrated the application of geographic information systems (GIS) in
managing and planning urban development, since this technology can be used to analyse and manage
spatial and non-spatial data from various sources and time period (Burrough and McDonnell, 1998; Yeh,
1999). However, GIS alone is still insufficient in strategic planning and monitoring urban spatial growth
(Geertman, 1999; Narimah and Ruslan, 2001) The application of geographic information systems (GIS)
and dynamic spatial models such as cellular automata (CA) has become popular recently since these
approaches can be used to locate, plan, map, monitor and forecast areas undergoing urban transformation (Batty, 1997; Clarke et al., 1997; Narimah Samat, 2002).
Cellular automata has gained significant interest in the recent literature since it is claimed to be capable
of simulating complex urban systems based on a series of simple transition rules (Couclelis, 1985). It
begins with a simple or a single cell and potentially capable of generating a complex behaviour when the
same rule is repeatedly applied at each iteration (Batty, 1997). Figure 1 shows an example of simple
cell evolution using a transition rule adopted from the Game of Life. The same concept was adopted
and used to simulate cell evolution from a small town to major urban area. Cellular automata have 4
basic elements: cells, a set of local states, a neighbourhood, and a transition rule (Couclelis, 1985).
These elements can be broadly defined to allow various kinds of rules or neighbourhood sizes to be
used in order to suite objects it represents. In modeling urban systems cells may represent land parcels
and states of the cells can be land use activities such as residential, commercial or agriculture.
Neighbourhood represents the cells immediately adjacent to a certain cells. There is no theoretical
guideline over the selection of the neighbourhood size, Von Neumann (cells located at the North, South,
East and West of the central cell in question) and Moore neighbourhood (cells defined by Von Neumann
plus cells at the NorthWest, SouthWest, NorthEast and SouthEast) is normally used (Batty et al., 1997).
These neighbourhood sizes are sufficient to capture the local interaction among cells, since the dynamic
nature of the model will be able to account for the diffusion of urban growth away from existing development. Transition rules determine the change of cells state during a subsequent iteration. It can be
deterministic or stochastic (Batty, 1997). However, most cellular automata model used to model urban
systems embedded stochastic elements or constraints to formulate a more realistic model. These
include incorporating various criteria

defining physical, social and economic characteristics of the urban areas under investigation.

Recently, many form of urban CA had developed in order to simulate the spatial pattern of an actual city
or a synthetic city (Batty et al., 1997; Yeh and Li, 2001). Various different transition rules such as
multicriteria evaluation approach, logistic regression and fuzzy logic (Wu, 1998; Wu and Webster, 1998;
Sui and Zeng, 2000) had been applied in order to ensure that these models could be used to understand
and simulate real urban systems. Although these models manage to mimic the behavior of urban
transformation, few of these models actually validate the output produced using the models. Chapin and
Kaiser (1979) and Sander (1996), however, stressed the importance of validation in model development
since this step allows the actual ability of the model to be evaluated. This phase of model development
is rarely conducted mainly due to insufficient of data sets to form a good validation parameter (Kok et al.,
2001).

MODELLING METHODOLOGY
Study Area
The study was undertaken in the Seberang Region, Penang State Malaysia, which is located in the
Northwest of Peninsular Malaysia. Figure 2 shows the location of the study area. It is centered at 5o 20N
and 100o 25E.

Figure 2: The study area.
This region is important since it is one of a few regions in Malaysia where rapid urban development of a
small town occurred as a result of industrialization. Seberang Perai is also a potential local center for
population and economic growth for the Northern region of Malaysia (SPMC, 1998). Malaysias population census 1991 revealed that this area accommodated approximately 545,688 people. However,
current population projections and related planning policies forecasted that this area would experience
about 60% population growth from 1991 figure (Dept of Statistics, 1991; 2000). This increase of her
population would require another 16% of land being converted to urban.
Model Formulation
The model was developed using a geographical modeling approach (Tobler, 1979) presently known as
cellular automata (CA) (Batty, 1997). This model has the ability to imitate the dynamic behaviour of
urban systems, which is useful to monitor urban transformation and land use changes. In this study, the
GIS-based CA model was developed to simulate the spatial pattern of urban growth since 1974. Study
area was divided into 30m grid resolution which can accommodate on average 4 unit of houses, the
number that required a planning permission to be develop (SPMC, 1993). Land use defined as state of
cells at time t, was represented by 5 major categories: urban, non-urban, wetland, forest reserved and
village. Only non-developed land, which comprised of less valuable agriculture areas, vacant land and
shrub, was available for new development. Neighbourhood was defined as a 3x3 cells representing
8,100m2 (average land parcel size in this study area) was thought to be sufficient in evaluating
neighbourhood influence on cell evolution.
The transition rules were derived from factors influencing urban development. These factors were
divided into site criteria and situation criteria. Site criteria used was soils, which defined suitability of
specific site for urban development. Situation criteria defined the relationship between sites and other
activities included proximity to major roads, proximity to employment centers, proximity to health facilities, proximity to schools, proximity to town centers, and proximity to developed areas (Chapin and
Kaiser, 1979; Eastman, 1999). Planning regulation that is the exclusion of paddy field agriculture from
any development was also included in the model. These factors were mapped and evaluated using a
multicriteria evaluation (MCE) approach. Weights reflecting their relative important in influencing urban
developments were assigned on the basis of information gathered at the study areas and interviewed
with local planners.
Subsequently, a MCE-generated suitability map was produced to form an input of the model.

The evolution of a cell was governed by the MCE-suitability value and the number of developed
neighbours within a neighbourhood. The formulation of the model is shown in Equation 1 below.

The Modeled Scenarios
In this study, a GIS-based CA was developed to simulate the spatial pattern of urban growth of the
Seberang Perai region using three planning scenarios. The three planning scenarios investigated were:
(i) A compact city model where urban development was only allowed to occur around existing urban
areas, (ii) an urban sprawl model which accounted not only for urban development around existing
urban areas, but also allow new development to occur non-contiguous to existing urban areas, and (iii) a
planned development model which took into account locations recognised within the regional strategic
plan already allocated for urban development. Each planning scenario was modelled using GIS, the
respective MCE-suitability maps and subsequent CA spatial simulation. Table 1 shows factors
influencing urban development and their respective weights with respect to modelled scenarios. For
each of the modelled scenarios, initial input was obtained from land use 1974 data and the model would
simulate the spatial pattern of urban growth until the number of developed cells matched with the total
developed cells (urban area) 1998.

RESULTS AND DISCUSSION
The actual urban areas of 1981, 1990 and 1998 were overlaid with the simulated urban areas of those
respective dates in order to validate the model. Figure 3 shows actual urban area from 1981, 1990,
1998 which were used to validate the model performance. Figure 4, Figure 5, and Figure 6 show the
spatial pattern of urban growth simulated using a compact development scenario, an urban sprawl
scenario and a planned development scenario respectively. All models managed to produce the spatial
pattern of urban growth that look relatively similar to actual urban areas. Furthermore, error matrix
tables for these three dates were also produced. Table 2 shows the validation result of the modelled
scenarios. Overall accuracy for the three model scenarios was quite high where a planned development
model produced the best accuracy that was 97.3% for 1981, 92.1% for 1990 and 88.8% for 1998. This
result, however, was only approximately 2-3% better that those produced using other scenarios.
Assuming that the transition rule and related MCE value used in the models were realistic, the result
suggested that urban growth in this area could be characterised by an expansion of existing urban
areas.

Figure 6: Simulated urban spatial pattern (from left) 1980, 1990 and 1998 obtained from a planned development scenario.
The analysis at a local level suggested that although the overall accuracy of the model was quite high, it
exhibited a different picture, where the accuracy for urban category modelled using a planned development scenario was around 67.9% (1981), 66.8% (1990) and 70.3% (1998). Figure 7 shows an example
of detail analysis at Butterworth, one of major towns in this study area. At local level, many pixels were
not accurately assigned to actual areas. This is due to either the limitation of the model in capturing
urban growth trends within the study areas or the approach is unsuitable to represent urban systems.
There were three factors contributing to the poor performance of the model. First, although the model
could very well capture urban expansion around existing urban areas, it failed to recognise urban growth
in an anisotropic manner (Narimah, 2002). For example, in some part of the study area, urban development can be characterised as ribbon-like development along major roads such as in the Southern
District, while the Northern and Central District experienced compact type of growth and in-filling of
urban development around existing urban areas respectively (Mohd Bazid, 2000; Mohd Hassan, 2000).
Another aspect that is attributable to the poor performance of the model is that the model considered
urban growth to be uniform across the study area. Thus, it tended to overestimate urban expansion in
areas undergoing less rapid urban growth. On the other hand, it underestimated urban growth in areas
experiencing rapid urban development. Finally, the third factor contributing to the poor performance of a
GIS-based CA model was its inability to recognise new urban development that occurred away from
existing urban areas. In the original CA type of model, vacant cells were urbanised based on their urban
suitability value and the states of cells within a 3x3 neighbourhood. This rule results in cells that were
highly contiguous to existing land experiencing a transformation from vacant to developed land (Engelen
et al., 1999). This, however, was not able to capture or simulate true urban growth that has occurred
away from existing urban areas. It should be noted, however, that these models had not accounted for
economic and social criteria such as land value and land ownership in determining cell suitability.
Further development of this model should attempt to incorporate these factors since they were likely to
have a significant influence on planning policy and hence land use allocation.

CONCLUSION
Although the evaluation of the model suggested that it produced approximately 30% to 35% spatial
error, the model could be used to describe and understand the spatial pattern of urban growth. It provided a broad understanding of the spatial pattern of urban growth that was useful at an early stage of
the planning process, by which planners could test different possible planning scenarios within a computer environment before actually choosing a specific plan. Furthermore, this model could be used to
evaluate various policy options in order to adopt a cohesive plan for urban areas.

THE APPLICATION OF GEOGRAPHICAL INFORMATION SYSTEM IN FOREST
ROAD PLANNING: A CASE STUDY OF COMPARTMENT 40 , DERAMAKOT
FOREST RESERVE, SANDAKAN, SABAH.
By
Rosila Anthony (Management and Mapping Division)
Raubin Gampilok, Paul Leo Lohuji (Forest Engineering Division)
Sabah Forestry Department
The concept of Sustainable Forest Management (SFM) planning in Sabah is not new. The good
forest management practices take cognizance of the multiple functions or uses of the forests with high
emphasis to its future productivity so that it is able to continuously contribute economically, socially
and environmentally. At different management level, SFM implementation generally comprises
planning procedure, implementing guidelines and monitoring tasks. Forest road planning is an
important component of SFM implementation.
Planning at the compartment level is operational in nature where the annual work plans and
Comprehensive Harvesting Plan (CHP) for the production compartment are prepared. Field operations
such as harvesting, rehabilitation, silvicultural tending and resource accounting, which takes into
account the changes in the growing stock and quality of forest stands, are planned, implemented and
recorded. In timber harvesting operation, Reduced Impact Logging (RIL) techniques are exclusively
carried out in Sabah. RIL operation includes the marking of trees for numbering and directional felling,
planning of road networks and skid trails aligned according to the location of trees and the terrain
conditions. Road planning is part of the Comprehensive Harvesting Plan (CHP) and it is one of the
most important activities of CHP preparation. A good road planning, which engages good preparatory
works prior to logging can facilitate economic harvesting through an improved harvesting system. It
will also results in less environmentally damaging harvesting operation as actual harvesting operation
is strictly done on established guidelines.
Conventional methods of forest road planning are time consuming, costly and error prone. New
methods of forest planning were designed to replace inefficient traditional methods. GIS is a new
technology that can be exploited for forest road planning. In this study, GIS technology is used to
evaluate potential Forest Road Network Options (FRNO) in Compartment 40 of Deramakot Forest
Reserve in Sabah. The specific objectives of the study are to plan different Forest Roads Network
Option (FRNO) through the application of GIS software using slopes, terrain condition, water-bodies
and harvestable trees position as criteria for road planning; to evaluate the net potential revenue that
can be generated from each FRNO by comparing road construction costs and sales from harvested
trees that lie within the road and skid trails buffer zones corridors and to select the best FRNO based
on the maximum net potential revenue.
The study required the study area to be surveyed for relevant information using sampling plots
of 20m x 25m. This will enable mapping of timber stock to be done along 92 lines that stretched for
4,600 meters. ArcView GIS software was then used to plan forest roads network options, taking into
consideration important parameters related to economic and environmental criteria. GIS technology is
used to calculate potential revenue of harvestable trees along the planned FRNO corridors. The
selection of best FRNO is then based on maximum potential revenue that can be expected from the
alternative FRNOs. The results of the study showed that the best FRNO is FRNO #1, which has the
maximum potential revenue of RM7.6 million. The results of the study suggest that automated
planning and preparation of forest road option network can be done using GIS.

ACQUISITION OF AN AIRBORNE LASER SCANNING SYSTEM (ALSS)
AND DIGITAL CAMERA SYSTEM (DCS) BY JUPEM
By
Wan Zainuddin Wan Yusoff and Faridah Hanim Sahak
Department of Survey and Mapping Malaysia
Mapping Division, Data Acquisition Section
KEY WORDS:
ALSS, Data Acquisition, DCS, Lidar, Small Format Digital Camera
ABSTRACT
By the end of 2004 JUPEM has fully commissioned its Optech ALTM 30/70 Airborne Laser Scanning
System (ALSS) and Digital Camera System (DCS) for laser terrain mapping. This paper presents a
conceptual outline of the systems and their functionalities.
1.
INTRODUCTION
The purchase of these systems serves to expand JUPEMs airborne mapping data acquisition capability
under the 8th. Malaysia Plan. Besides classical digital photogrammetry and the use of spaceborne
remotely-sensed data, laser terrain mapping can provide new avenues in expediting the production of
orthophotos and the national base maps.
2.
WHAT IS ALSS?
ALSS is an active system which utilizes LIDAR technology. The system sends out narrow pulses or
beams of light to objects on the earth surface which are then reflected back to the system receiver. The
system then times, counts and process the reflected light.
Laser measurements depend on knowing the speed of light to calculate how far the returning light
photon has traveled to and from the surface object:
Distance = (Speed of Light x Time of Flight) / 2
Accuracies to be expected from laser terrain mapping for an open area type of terrain are as follows:
Elevation : + 15 cm (1 sigma) at 1200 m
Posional : + 1/2000 x altitude (1 sigma)

Oleh
Nornisha binti Ishak
Seksyen Perkhidmatan Pemetaan
Jawatankuasa Kebangsaan Nama Geografi (JKNG) telah mengadakan mesyuarat tahunan kali
ke-3 bertempat di Kota Kinabalu, Sabah pada 14 Jun 2005. Mesyuarat yang telah dipengerusikan oleh
Encik Ahmad Fauzi Bin Nordin, Pengarah Ukur Bahagian Pemetaan selaku setiausaha JKNG, telah
dihadiri oleh wakil Setiausaha Kerajaan Negeri dan Jabatan/Agensi Kerajaan Persekutuan yang
menganggotai jawatankuasa ini iaitu seramai 29 orang.
Tuan Pengerusi sedang mempengerusikan
Mesyuarat Ke-3 JKNG yang diadakan di Hotel
Pacific Sutera, Kota Kinabalu, Sabah.
Mesyuarat JKNG ini telah dihadiri oleh ahli-ahli seramai
29 orang yang terdiri daripada wakil Setiausaha
Kerajaan Negeri /Jabatan / Agensi Kerajaan
Dalam ucapan pembukaan, Tuan Pengerusi menjelaskan bahawa JKNG bermula daripada
keanggotaan Malaysia dalam United Nations Group of Experts on Geographical Names (UNGEGN).
Keanggotaan Malaysia ini bertujuan untuk memperkenalkan satu kaedah yang konsisten dan tepat
dalam menggunakan nama-nama geografi bagi keberkesanan komunikasi di peringkat antarabangsa
dan juga bertujuan untuk membantu di dalam pembangunan sosioekonomi dan pemuliharaan alam
sekitar serta infrastruktur. Oleh yang demikian, pengwujudan JKNG ini adalah wajar dan tepat pada
masanya bagi menyelaras dan menetapkan piawaian nama-nama geografi seluruh negara.
Tuan Pengerusi juga turut memaklumkan mengenai beberapa kes yang melibatkan aspek
toponimi seperti urusan penukaran nama geografi. Di antara kes yang dibangkitkan ialah mengenai
penukaran nama Pulau Perak kepada Pulau Kedah oleh Pihak Berkuasa Kerajaan Negeri Kedah.
Walaubagaimanapun, keputusan penukaran nama tersebut telah dibatalkan oleh Majlis Mesyuarat
Kerajaan (MMK) Negeri Kedah apabila Jabatan Ukur dan Pemetaan Malaysia (JUPEM) memaklumkan
bahawa pulau tersebut merupakan salah satu titik pangkal yang menentukan zon maritim negara dan
titik pangkal ini juga termaktub di dalam perjanjian di antara Malaysia dengan negara jiran. Sekiranya
penukaran nama dibuat, ianya akan melibatkan implikasi bagi zon maritim di sebelah Selat Melaka
kerana masih terdapat tuntutan yang dibuat oleh pihak Indonesia. Sehubungan itu, beliau
memaklumkan bahawa isu penukaran nama tersebut selaras dengan salah satu dasar yang telah
disertakan dalam garis panduan yang mana urusan penukaran nama perlu dibuat dengan berhati-hati
dan sekiranya melibatkan aspek perundangan, adalah dinasihatkan supaya penukaran nama tidak
dibuat.

Preparation to Workshop
With the requirement from ESRI, participants need to ensure that they are well prepared for the training.
Prior to attendance, all participants need to sign a license agreement. This agreement must be signed
and returned to ESRI prior to participant being allowed to attend the workshop.
All participant also needs to make sure that they have all the software and hardware well installed and
ready as required in the programme. Everyone should complete the specific exercise of the workshop
which is given earlier by email from ESRI before they come to Hong Kong. This exercise goes through
the Environment Verification, making sure that each machine has ArcIMS and ArcSDE properly functioned and working, as well as ensuring that all the required 3rd party software has been downloaded.
5.2.
Programme Module
The ESRI GIS Portal Toolkit consists of four modules: a portal framework, a map viewer, an administration tool, and a publication tool. Training for each module is covered within a half-day, and one additional day can be used to answer general questions on the usage of the portal toolkit in developing GIS
portals. The ESRI GIS Portal Toolkit includes a sample application for each of the modules that can be
installed and configured to quickly set up a basic GIS portal.
During the three-day workshop, four modules of the ESRI GIS Portal Toolkit has been installed on
hardware provided by the workshop attendees themselves. The workshop addresses the architecture of
the ESRI GIS Portal Toolkit, the integration of the four modules, and the creation and population of the
resulting GIS portal with metadata.
The whole workshop has been conducted by Margaret Lyszkiewicz, The Internet and Metadata Products
Specialist from ESRI, USA., while Guest Speaker, Dr Winnie Tang, CEO, ESRI China (Hong Kong)
Limited has opened the workshop by welcome address and introduction of ESRI and its products.
After an extended introduction about metadata and other concepts related to geospatial portal, the
Instructor addressed the architecture of the ESRI GIS Portal Toolkit, the integration of the four modules,

ROYAL ADELPHI, SEREMBAN, NEGERI SEMBILAN
27 JUN 2005
Oleh
Abdul Manan b. Abdullah
Ketua Penolong Pengarag MaCGDI
Mesyuarat Jawatankuasa Teknikal Framework dan Clearinghouse ini bertujuan untuk menggariskan
cadangan mengadakan Mesyuarat Jawatankuasa Teknikal Clearinghouse dan Framework bagi negeri
yang telah melaksanakan Clearinghouse MyGDI dan makluman 8 negeri baru untuk melaksanakan
MyGDI , anjuran Pusat Infrastruktur Data Geospatial Negara (MaCGDI), Kementerian Sumber Asli dan
Alam Sekitar.
MyGDI merupakan satu projek peringkat nasional di mana kementerian sebelum ini dikenali sebagai
Kementerian Tanah dan Pembangunan Koperasi, telah dipertanggungjawabkan oleh kerajaan untuk
melaksanakan projek ini.
Bagaimanapun Clearinghouse MyGDI yang telah digunakan di empat negeri iaitu Kedah, Perlis, Melaka
, Sabah dan termasuk Wilayah Persekutuan Kuala Lumpur dan Labuan didapati masih tidak mencukupi
kerana negeri lain masih tidak dapat untuk melaksanakan MyGDI serta menggunakan maklumat GIS
didalam tugas-tugas harian.
Oleh kerana itu, didalam Rancangan Malaysia ke 8, MyGDI akan diperluaskan ke 8 negeri yang lain
iaitu Selangor, Perak, Pahang, Pulau Pinang, Negeri Sembilan, Kelantan, Terengganu dan Johor.
Tujuan utama diadakan Mesyuarat Jawatankuasa Clearinghouse Dan Framework ini adalah seperti
berikut:
1. Membentangkan aktiviti-aktiviti MyGDI di setiap negeri bagi membincangkan berkaitan dengan ;
·
Penambahan data dari agensi
·
Penambahan agensi baru
·
Penambahan dataset bagi agensi yang sediaada
·
Penentuan harga data
·
Penambahan data JUPEM seperti sempadan dan pendigitan data hardcopy
·
Penggunaan talian
2. Menbentangkan perkembangan data dari Agensi Berkuasa Tempatan (ABT) dan juga
perkembangan berkaitan dengan perkakasan dan perisian.
3. Sebagai makluman, MaCGDI sekarang dalam usaha membangunkan National Data Center
(NGDC), selaras dengan Perlaksanaan Perakuan Kajian Pentadbiran Daerah dan Tanah
dengan Tumpuan Kepada Urusan Tanah yang dilaksanakan oleh Kementerian dan MAMPU.
4. Perancangan bagi penyediaan tapak bagi Clearinghouse MyGDI negeri-negeri baru
.
Memberi penerangan tentang keperluan asas sebelum membuat perlaksanaan untuk
peralatan serta keperluan lain yang perlu dari segi talian elektrik, penghawa dingin,
serta lain-lain keperluan.
5. Perancangan bagi rangkaian komputer bagi melaksanakan MyGDI
.
Memberi penerangan tentang keperluan rangkaian yang akan dibangunkan, dari
segi kelajuan dan lain-lain keperluan yang melibatkan rangkaian.
38
Perbincangan mengenai penyediaan data bagi agensi NRE termasuklah cadangan produk data baru,
agensi pembekal dan lead agensi baru dipilih bagi menentukan keperluan dan kepentingan data kepada
agensi-agensi dan orang awam. Ini adalah bagi memastikan data tersebut dapat digunakan
sepenuhnya oleh agensi dan orang awam untuk tujuan pembangunan negara khususnya.
Tugas-tugas jawatankuasa teknikal clearinghouse adalah lebih kepada pengurusan Infrastruktur
diperingkat negeri dan persekutuan, melibatkan penyebaran maklumat (setelah data dikutip dan
dipublish) dan Human Resourses Development (mengenalpasti keperluan latihan).
Hasil dari bengkel Framework ini, beberapa perkara telah diputuskan dan diambil tindakan dan
rumusan tersebut adalah seperti berikut :
a. Mengenalpasti tema dan dataset framework serta penyumbang data tersebut.
b. Keperluan kepada data spatial yang sesuai untuk dijadikan data framework dan
penyumbangnya
c. Mewujudkan polisi dan garispanduan mengenai binaan dan perpindahan data kepada
pengguna dengan mengambilkira isu-isu harga data, hakcipta, royalti and kerahsiaan.
d. Mengenalpasti dan menerima-pakai common coordinate reference system.
