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

2.0 MYGDI AS MALAYSIAN SDI

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.

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).

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
