Spatial Metadata is information that describes spatial datasets. This provides
a consistent approach to allow the storage and retrieval of information about
a particular dataset. An analogy may be the labeling of food on supermarket
shelves or historical information about a motor vehicle in a second-hand car
Metadata can be accessed using database and internet technologies that automate
search and retrieval capabilities. This is done through the ASDD.
what is ANZLIC doing?
ANZLIC has historically delivered metadata standards and profiles based on
international best practice. One of the standards that the ISO Technical Committee
for Geographic information/Geomatics (ISO/TC 211) is working on is a standard
on metadata known as ISO 19115 (the International Standard for Metadata). This
International Standard is currently being published. There has been extensive
input by Australia during its development, particularly from interests associated
with ANZLIC, and as a result, ISO 19115 incorporates several ANZLIC core metadata
Similar metadata standards for the description of geographic data, such as
ANZLIC's Metadata Guidelines, are currently in use around the world. Until the
development of ISO 19115, there had been no unifying set of metadata elements
that could be used as the basis for the development of national metadata standards.
The development of the ANZLIC Profile for ISO 19115 is currently on hold until
Geographic Information Working Group Metadata Working Party reports its
findings and example XML schemas for Work Item ISO/AWI 19139 (Geographic information
– Metadata – Implementation specification). ANZLIC has based this
decision on advice received from the United States' Federal Geographic Data
Committee (FGDC), the Australian representative on ISO Technical Committee for
Geographic Information/Geomatics (ISO TC211), and some jurisdictional responses
to the initial draft of the ANZLIC Metadata Profile released in 2002.
ANZLIC works closely with Standards Australia/Standards New Zealand (sponsoring
Australian participation at international ISO/TC211 meetings), and with the
Intergovernmental Committee on Surveying & Mapping (ICSM) and PSMA Australia
Limited to raise the awareness and uptake of geospatial standards.
ANZLIC Metadata Guidelines
ANZLIC has developed a metadata standard which sets out minimum requirements
for metadata to be included in the ASDD. The ANZLIC
Metadata Guidelines (v2 – February 2001) is designed for use
by data custodians to assist them create, store and distribute core metadata
elements and have been widely adopted. The document includes introductory information
on metadata, its use and its management. References include sources of more
detailed information that users may require as they become more experienced
with metadata and its use as an aid to data management within their own agencies.
ANZLIC plans to ensure that they comply with international metadata standard
ISO 19115—which has recently been registered for final approval as a Final
Draft International Standard (ISO/FDIS 19115)—and is expected to be formalised
Geographic Extent Name (GEN) Register
The GEN Register is an online resource that contains the geographic extents
of thousands of geographic objects. These objects range from maps sheets, navigational
charts, oceans and rivers, through to States, Territories and Local Government

ANZLIC Metadata Entry Tool
The Metadata Entry Tool (MET) is a freeware
application, developed by ANZLIC, to facilitate the collection of consistent
descriptions of core metadata elements for publishing on the Australian Spatial
Data Directory (ASDD).
