The Five Priorities for Implementing the ASDI
Governance
6
Geospatial Data 1.01

• A 60 second overview in Geospatial Data
• A look at the data described by Geospatial
  metadata

7
Vector Data Point Feature
8
Vector Data Line Feature

Vector Data Polygon Feature
10
Raster Data Satellite Imagery

13
Geospatial Data 1.01

• Spatial Data is great for drawing maps
• BUT
• The true power of Spatial Data lies in
• Our ability to visualise patterns and see
  relationships that would otherwise be hidden in
  raw data (tabular data Vs spatial data)
• And through GIS perform more advanced geographic
  analysis

The current national metadata standard

16
Discovering Geospatial Metadata

• ASDD Australian Spatial Data Directory
• Online directory to enable spatial data discovery
• Hosted by Geoscience Australia
• 25 Nodes 39,000 Records
• Most cases Metadata Only Limited data
• Vision would be a dynamic link between Metadata
  and data

Metadata a retrospective

• Pages concept - accepted theoretically but not
  implemented uniformly (except for Page 0
  metadata)
• MS ACCESS Metadata Entry Tool (MET) - success to
  a point, but its maintenance became untenable
• Agency and in some cases jurisdictional (eg. QLD)
  web based entry tools exist
• Poor alignment with Dublin Core metadata standard

19
The new ISO Metadata Standard

• July 2003 ISO, the International Organization
  for Standardization, announced the approval and
  publication of ISO 19115, Geographic information
  - Metadata.
• Introduced concept of profiles, customisation of
  standard to fit a particular community of
  practice.
• 420 Elements (Mandatory, Optional Conditional)

20
Implementing the new ISO Metadata Standard

• July 2003 ISO Technical Committee 211 approved a
  project to develop ISO 19139, Geographic
  information - Metadata - Implementation
  specification
• Due for release July 2005

21
Metadata Dark Ages (2002 04)
22
The last 12 18 months

• NZ Geospatial metadata standard (19115-like)
• BRS metadata standard (99 compliant)
• Australian Govt profile (OSDM Metadata Working
  Group Dec 2004) the catalyst
• Jurisdictional efforts, especially WA
• ANZLIC Metadata Workshops (Perth Melbourne Feb
  2005)

23
ANZLIC Metadata Workshops

• Approx 100 attendees
• All jurisdictions vendors/ industry
• Game plan formulated
• Develop a ISO compliant national profile based
  on the Aust Govt profile
• Need a free MET

24
ANZLIC Metadata Project

• Approved by ANZLIC Council on 8 March 05
• 3 Outputs
• WA (WALIS Office) to project manage
• ANZLIC National Office to coordinate
• Target date September 05 SSI Conference

25
The Project Team

• Primary Project Team
• WALIS, ANZLIC, Vic DSE, OSDM, GA, LINZ, AODCJF
• Additional Support
• DEH, Office of Economic Statistical Research
  QLD, BRS, NLWRA

26
Project Outputs

• New ANZLIC Metadata Profile
• Alignment of existing profiles
• Aus Gov, NZ, WA and Aus Marine Community
• Agreed principle-based approach following ISO
  obligations, using ISO def. with Aus examples
• Development of UML diagrams, documentation and
  agreed code lists
• Development of XSD for MET

27
Project Outputs

• MET Development
• Review of existing tools
• Technical Specifications from WA, GA, OSDM, LINZ,
  AOCDF
• XML based technologies
• Freely Available

28
Project Outputs

• Education Outreach
• Project information Sheet
• Update email through ASDI-L
• SSI Conference Melbourne Sept 05
• Hardcopy / softcopy / online publication of
  profile documentation
• MET Softcopy / online

29
New Profile Implications

• Metadata in ASDD is ANZLIC V2 compliant
• XSL to translate from ANZMETA 1.3 to new ANZLIC
  Profile
• Validation tools
• Requires strong in-house data information
  management including conversion of V2 to new
  profile

30
ANZLIC Metadata Project

• Considerations for DC-ANZ
• Vision is for
• Seamless cross over between community of practice
  with in Geospatial community
• Translation capability between Dublin Core and
  ANZLIC ISO Metadata Profile - OSDM
• Requires a tool, an XLST to handle the XSL

31
ANZLIC Metadata Project

• ISO 19115 is complex and based on hierarchical
  relationships
• Within records / Between records
• AGLS flat file structure
• No competition
• Complementary relationship, option for richness
• Commitment to link NDN (AGLS) to ASDD (ISO19115)

32
Current Status

• Short ANZLIC ISO Metadata Profile
• Long Australia New Zealand AS/NZS 191152005
  geospatial metadata profile version 1.0
• Profile harmonisation process finalised
• Technical Specification for MET complete
• MET going to tender
