Critical Review of SDI
  • Geotechnology the world third largest sector
  • Spatial Data crucial to decision making process
  • NSDI to overcome data sources barriers
  • Diversity of geospatial data, to train more
    expert knowledge in data manipulation and
    information technology
  • To increase the effectiveness of SDI applications
    to meet users expectations
  • To widen the range of services in the application
    to accommodate wider user needs
  • To integrate focussed applications such as
    project on e-KL, e-PBT, e-Desa, etc under e-Govt
    with MAMPU, Ministry of Housing, etc.
  • Web Services Technology SOA and adaptation of
    Geoportals, shift from data centric NSDI to a
    service-oriented one.
  • Actual potential of service-oriented SDI is yet
    to be realised.
  • SOA-based SDI will destruct silo-based
    organisation that exist today and the emergence
    of Virtual Organisation.

Why SDI?
  • Geospatial Data Explosion
  • Major advances in technology
  • Explosion in availability of source data, in
    particular satellite imagery
  • Increasing creation and sharing of spatial
    information over the Internet
  • 3-D explosion, with most sectors now expecting
    the ability to view spatial information in 3-D
  • Increased expectations of data quality

Too Many Geospatial Data to Manage!

2.0 MYGDI AS MALAYSIAN SDI
9
Implementing SDI in Malaysia
  • Malaysia Geospatial Data Infrastructure (MyGDI)
    is the Malaysian version of SDI. Similar to other
    SDIs, following figure shown the ultimate reason
    for implementing the MyGDI is to provide access
    to spatially geo-referenced information.

10
MyGDI At A Glance
  • MyGDl is an initiative by the government to
    develop a Geospatial Data Infrastructure to
    enhance the awareness about data availability and
    improve access to geospatial information by
    facilitating data sharing among participating
    agencies.
  • MyGDI, as the National Spatial Data
    lnfrastructure (NSDI) Malaysia, is a geospatial
    data infrastructure that comprises technology,
    policies, standards and procedures for agencies
    to cooperatively produce and share geospatial
    information. MyGDl provides a basis for
    geospatial data exploration, evaluation, and
    application for users and providers within all
    levels of government, commercial, and non-profit
    sectors as well as the academia and the public.

MyGDI Standard
  • In data sharing and exchange, there are three
    types of geospatial related standards
  • content standards - parcel identifier, features
    and attributes code catalogue and geographic
    place names
  • access standards - standards in data
    communication such as ISO 19100 series for
    geographic information
  • exchange standards - XML and GML

National Geospatial Data Centre (NGDC) Geospatial
Data Preparedness
  • Facilitate geospatial data sharing among the
    government agencies,
  • Support access to geospatial information by all
    levels of government and by the public in
    general.
  • Support the business of the government that
    requires geographic components and tools to
    handle and manage the geospatial data.
  • Facilitates cross-agency decision-making that
    involves geospatial information.

3.0 SDI/SOA LATEST TECHNOLOGY
20
Latest Middleware for Data Integration / Data
Sharing
  • GeoSamba Universal
  • Sophisticated mapping and geographic analysis
    system with the power to share location
    intelligence across business processes and
    enterprise systems.
  • Erdas RedSpider
  • Offers full SDI solution. Interoperable exchange
    and publishing of geospatial information with
    OGC/ISO, manage and organize geospatial
    information, develop robust Java application with
    a complete fine grain Java Api for GML and other
    OGC standards, solve imagery dissemination over
    the Internet with OGC/ISO.
  • Weave
  • Business integration framework for combining
    disparate information systems in an easy to use
    environment. Based on Open Systems technology
    that is independent from vendor-specific
    technology such as propriety Application
    Programming Interfaces (APIs).

GeoSamba Universal Architecture
22
GeoSamba Universal Benefits
  • Operational Advantage
  • Removes limitations on the ready use of spatial
    data
  • Increased span of control
  • Efficient and easily implemented spatial business
    transactions
  • Timeliness
  • Complex processes quickly built and implemented
  • Freedom from
  • Proprietary databases
  • Legacy database/warehouse solutions
  • Future database/warehouse decisions
  • Limiting analysis to internal sources
  • Significantly reduced Total Cost of Ownership
    (TCO)
  • Access external data sources
  • Rapidly model complex processes

DBKL GISNet System Overview
  • DBKL GISNet system is a depository hybrid /
    centralised GIS database integrating spatial
    information from five (5) departments in DBKL
  • Health Department (JK)
  • Landscape and Urban Cleanliness Department
    (JSTKPB)
  • Master Plan Department (JPI)
  • Planning Department (JPRB) and
  • Valuation and Property Management Department
    (JPPH).
  • The spatial data centre is located at Information
    Technology and Communications Department (JTMK)
    who will be responsible in fundamental datasets
    maintenance and acquisition.
  • DBKL GISNet system follows the policy, data
    framework and standards as laid out by MaCGDI in
    facilitating, coordinating and managing ultimate
    geospatial information.

Data Sharing Issues
  • Issues encountered during the development of DBKL
    GISNet
  • Data sharing is made impossible due to self-made
    GIS
  • Unstandardised UPI between DBKL and JUPEM
    (involving almost 50 of parcel layers)
  • Duplications and incompletion of data
  • Draft Plan Kuala Lumpur used incorrect UPI
    unable to create lot query for Public

5.0 Recommendations to Spatial Organisation
  • Legal Framework Governing Data Sharing of
    Geospatial Data
  • All spatial organisations to effectively sustain
    and exploit MyGDI
  • Data Framework at Sectoral Scales
  • Sectoral Data Services to build business
    applications
  • A support research and development agenda
  • To rebrand GIS towards Business Geoinformation
    and Earth Sciences for Government and Industry
