What is spatial?
What is spatial information? “Spatial information …describes the physical location of objects and the metric relationships between objects. ” Google Maps Initially, spatial information was accessed in the form of a paper map Google Maps Google Earth Even aerial photography was easily available for a price Now Web 2. 0 allows mashups to create freely available spatial information online.

Community Expectations - Case Studies
The Impact of Spatial Case Study I If we get it right: “Energex is an electricity distributor servicing about 2. 7 million people in South East Queensland. It has • $6. 6 billion in assets • covers 25, 000 sq. km. • 50, 000 km of electricity lines and cables • half a million power poles • 43, 000 transformers and 290, 000 street lights. ” When Energex upgraded their geospatial technology in 2005 by linking their customer systems with the existing GIS: • They found “$500 million worth of assets” • Prior to the upgrade, Energex operated a call centre with 10 people involved in handling emergency calls. The same load is currently handled by only 1 person. ”

The Impact of Spatial Case Study III In the ACIL Tasman report, prepared for the CRC for Spatial Information in March 2008, it was found that: • Australian Government agencies spent around $85 million on spatial data production and management in 2006 -07. • geospatial information has enhanced the way in which many Australian Government agencies plan and deliver services. • 67% of agencies expected to reduce costs significantly due to improved business processes and 64% expected to reduce staff costs and other direct costs.
The Impact of Spatial Case Study IV Western Australian Government study - 2004 A Western Australian Government Taskforce found that substantial gains were likely from integrating land geographic data held by State agencies. This integration would include: • • steps to clarify data custodianship, the establishment of a land information directory, standard procedures for data collection, and improved marketing of data. The annual costs of integrating land information were estimated at $1. 8 million and the potential annual benefits at $10. 7 million – resulting in a benefit/cost ratio of 5. 9 : 1
The Impact of Spatial Case Study V The Western Australian Land Information System (WALIS) is an alliance of diverse public and private sector organisations, as well as community groups. It: • oversees the management of spatial information across the state community, and • it coordinates capture of fundamental spatial data through the State Land Information Capture Programme.
The Impact of Spatial Case Study VI Case study - asthma The Australian Institute of Health and Welfare’s latest Burden of Disease and Injury report shows that • 4, 045 years of life (YLL) were lost to asthma in 2003 – this is due to premature deaths attributed to the disease • in addition to the 59, 054 years of life with disability (YLD) attributable to asthma in 2003. Even a conservative valuation of $150, 000 per YLL and $50, 000 per YLD would put the total loss to Australia due to asthma alone at $3. 6 billion in 2003. More accurate spatial information enabling a 10% reduction in these figures would therefore be worth at least $370 million per year.

Defining the problem
Spatial Impact on the Australian Economy The [ACIL Tasman] study estimates inefficient access to data reduces the direct productivity of some sectors by between 5% and 15%, and highlights the reasons for this.

Using labels to locate resources If we start with an object… … we will need to answer some questions about it…
Using labels to locate resources Is there a user guide? Who created this? When? What intellectual property rights are vested in the object? What format is it? What software will I need to render it? Is this software currently available? Are there any other dependencies? Is it related to other objects located within this (or any other) repository? Can I be sure that the object is what it claims to be? Who currently has custody of this? Who updated it? When? Has the object been updated?
Business benefits of using a standard label • Valuing your data as a business asset • Being able to locate the data Only 20% of enterprise documentation may exist in paper format. 1 This is equivalent to “Information workers 2. 2 hrs per day spend up to 30% of or their working day just $15, 000 of a looking for data they need $50, 000 annual salary to complete a task…” - Butler Group Dec’ 06 (based on a 36. 75 hr week) In other words, for an organisation with 1, 000 staff at this pay level, $15 million a year is spent looking for company information out of existing systems.
Business benefits of using a standard label • Valuing your data as a business asset • Being able to locate the data • Fitness for purpose Across Australia, almost 50% of employees find the greatest obstacle to how they make decisions at work is the lack of accurate, consistent and complete information. 3
Business benefits of using a standard label • Valuing your data as a business asset • Being able to locate the data • Fitness for purpose • Effective risk mitigation tool 90% of the documents that are created have no useful metadata. As a result, as much as 10% of a company's salary costs are wasted on ineffective searches. 1 Overcoming ineffective searches is certainly a priority for law firms due to changing regulatory and risk considerations. 1 Poor information leads to poor decisions, wrong information leads to wrong decisions.
Locating the resources

Finding the information A growing portion of the Web cannot be indexed by standard search engines. Databases… create "pages" dynamically on demand for an individual user, and thus are not available for a search engine's spider to scan. This is often called the “Deep Web”
Structured Searches
The solution – structured searches How can I find a particular resource at my workplace? e. g. the 1999 Annual General Report for your division Using the search function in your file management system, your success will depend on how the file was initially labelled before saving. Final Annual Report 30 -6 -99 30 Jun 1999 CSDC Annual 1999 Annual. Report General Report 30 Jun 1999 OSDM Draft General Report General 30 Jun 1999

The solution – structured searches So you need structured information that describes, explains, locates or otherwise makes it easier to retrieve, use or manage an information resource. This is Metadata. It is simply a file that sits with each record and provides background information about that record that is “computer readable”. Courtesy of North Caroline State Archives
Discovery Metadata is the starting point for access as it provides the means for ‘discovery’ of spatial information. e. g. the Australian Spatial Data Directory However • metadata remains in many formats; and • many are currently not completely valid. For example, a recent study of 5, 141 metadata records of NSW natural resource sectors confirmed that the records were out of date and could not be automatically upgraded to fit the ANZLIC 19115 profile.
Discovery If you create metadata, other people can discover your data. If you create metadata, you can find your own data.
Metadata
What’s Metadata? • A painting by Gauguin sold at two Auction houses at the same time. Sotheby’s had the real one… • How did they know? Lilac Bouquet 1885 • One painting had provenance (metadata). • One didn’t.

What’s Metadata? Metadata is information about a resource that can be used to identify, assess and access that resource without actually having to touch that resource. Identify • keywords • geographic location • time periods • attributes Assess • use constraints • access constraints • data quality • availability/pricing Access • online access • order process • contacts

Standards
Standards • The International Organization for Standardization (ISO) is a world-wide federation of national standards bodies. • It is responsible for promoting the development of standards to facilitate the international exchange of goods and services. www. oceantrader. com www. fortunewatch. com
Standards A popular geographic standard, ISO 19115, contains almost 300 metadata elements, most of which are optional. The ANZLIC 19115 profile is made up of 24 of these elements. Another commonly used archival standard is Dublin Core and the Australian Government Locator Service (AGLS) was derived from a hybrid of this and ISO 19115. The AGLS and ANZLIC profile are regularly reviewed an overview of common elements is available.
Standards A standard establishes: • common terms • common definitions • common structure (whether an element is mandatory, conditional on another element, or optional) • a method for extending the profile to address specialized or custom needs ab·stract (for adj. , ab strakt, ab′strakt) adjective • thought of apart from any particular instances or material objects; not concrete • expressing a quality thought of apart from any particular or material object beauty is an abstract word • not easy to understand because of being extremely complex, remote from concrete reality, etc. ; abstruse • theoretical; not practical or applied • designating or of art abstracted from reality, in which designs or forms may be definite and geometric or fluid and amorphous: a generic term that encompasses various nonrealistic contemporary schools
The value of standard labelling When it goes wrong… “Two Teams, Two Measures Equaled One Lost Spacecraft” “A team of Lockheed Martin engineers sent NASA key manoeuvring data for the $125 million Mars Climate Orbiter in non-standard units, probably since the craft was launched in 1998, according to a NASA official trying to explain the loss of the craft. © NASA Miscalculations due to the use of English units instead of metric units apparently sent the craft slowly off course – 60 miles in all – leading it on a suicide course through the Martian atmosphere. House Science Committee Chairman F. James Sensenbrenner, Jr. , sounding stunned, released a twoword statement after hearing the news about the miscommunication: "I'm speechless. "
