- Simple definition:Information about anything that is referenced
to the Earth. Also known as spatial information
- Location data is comprised of:
-
- Attributes (e.g. road name, road type etc)
-
- Spatial context point, linear, area
- Where does location data come from?:
-
- Maps (usedsince 2300 BC Babylonian clay tablets)
-
- Aerial photographs & Satellite imagery
What is location information? 5. 2 key types of location data
Source: www.innovativegis.com 6.
- Delivery of location based information via the internet
-
- But its more than just a map!
-
- Fundamental to the development of the Geoweb
-
- Leverages Web 2.0 concepts / philosophy location can be
considered as a key element for making the internet closer to the
real world.
-
- Strong visualisation of information
-
- Large amounts of information stored/delivered
-
- Potentially rich with functionality
-
- Commercial Google maps/Earth, Whereis.com.au
-
- Government SIX portal, WA SLIP portal, GA Sentinel & GA Map
Connect
What is web mapping? 7.
- AJAX (group of technology: Asynchronous JavaScript and
XML)
- Server side technology (thin client)
- Rich Internet Application
- Spatial Web services that follow theOpen GIS Consortium(OGC) eg
WMS, WFS
- Mash ups (content derived from third parties)
Typical web mapping technology 8. How does it work? 9.
-
- Location: what is at, where am I, how do I get to?
-
- Temporal: what has changed since?
-
- Proximity: what assets are located withinxkm of?
-
- Query: where is something found?
What business questions can you answer?

- Nielsen report that Google maps had 71.5 million unique hits
during October 2007, & GE 22.7 million users .
- Microsoft have purchased the UK Multimap web mapping site
- Nokia purchased Navteq for > USD $8 Billion
- Location information is worth $1.37 billion to the Australian
economy & adds up to $12.6 billion to the GDP(source SEGS08
conference)
How big is the web mapping market? 12. Why use web mapping in
e-Government? . . . And Making It All Accessible Managing
Complexity . . . Location answering the where is? accessibility Use
Source: www.esri.com adapted by NSW Department of Lands 13. How
does Government use web mapping? Source: Adapted from www.esri.com
Planning quickest routes, asset management Emergency departments
Identifying areas of risk from e.g. fire, flood Environment
agencies Health impact assessments Health Manage land titles State
government Exploration license location, ore movement Mining
Managing pipe networks Utilities Monitoring routes Transport To
link clusters of disease to sources Epidemiology Crime mapping to
target resources Police Inventory and management of resources
Forestry Use of location information Industry 14. Benefits of web
mapping in e-Government?
- Massive demand for timely, relevant information picture says a
1000 words
-
- Provide users with all the information required to make an
informed decision (Simplecomplex)
-
- Ability to integrate vast amounts of data within one
environment (direct links to source of truth Govt DBs)
-
- Exploit visualisation techniques to present information
according to user preference (Raster, vector, 3D, tabular etc)
-
- Visualise /identify patterns/trends etc
15.
- Identify clear business purpose (who are you targeting?)
-
- What information & functionality to provide?
-
- Up to date, accurate, supported with metadata
-
- How to deliver 1000s of datasets?
-
- Volume of data (storage) pressure on bandwidth
-
- Balance needs of Business users & Mums & Dads
-
- Information architecture?
-
- Security, Privacy, Policy & copyright
Challenges to web mapping in e-Government 16.
-
- Case Study NSW SIX Portal
How can these issues be addressed? 17.
- The Spatial Information eXchange is a cross government
initiative to spatially enable NSW
- Spatial Information eXchange (SIX) has 3 main functions:
-
- Search and discoverspatial (location based) information. This
includes options to search and display data using specialised
viewers or through direct access via web service channels )
-
- Real time accessto up-to-date government information. Key base
data include: addresses, cadastre, topography and high resolution
imagery
-
- It is asecure gatewayto spatial information, government
registers and land and property related searches
NSW SIX Portal 18. NSW SIX Portal six.nsw.gov.au 19.
- Display up to date Govt data tailored to users specific
needs
- Find and display areas of interest
- Integration of imagery, geographic theme and textual
information with supporting metadata
- Query Govt databases to display descriptive information on
geographic themes
- Personalisation for different business users
- Empower users to diagnose system issues
-
- Consume other Govt web services eg BOM weather info
-
- Empower users to mark up areas of interest and share with
others

- Choice of technology was driven by:
-
- Leverage existing Govt architecture
-
- Need to provide direct access to Govt source of truth
systems
-
- Functionality to display and query Govt databases
-
- Leverage Web 2.0 concepts
- Technology needs to be fit for purpose
SIX Technology 26.
- Need to balance needs of Mums and Dads users with professional
users
- Develop a lite version of the site.
-
- Independent review by usability expert
-
- Balance user convention with innovation
-
- Ideally minimisebuttons without reducing functionality
-
- Empower users to mash up and extend interface themselves
-
- Provide framework for interface to scale with user
experience
SIX Lite target Mums & Dads users Source:

& SIX
- Linkages with NSW State Plan
-
- Maintain and invest in infrastructure
-
- A higher productivity economy
-
- Building harmonious communities
-
- Simplifying Government processes e.g. tailoring electronic
services
- Linkages with GCIO People First Plan
-
- Integrated with Channels and Access
-
- Government Shared Service
-
- Consolidates spatial information and property holdings
-
- Provides equitable (fairness) access to core information
stores
29.
- Ongoing review of usability
- SIX Lite toolbox empower users to enrich user experience by
adding additional tools to interface
- Increased integration (mash up) of information.
-
- Enhance mash up tools (empower agencies/users to add more of
their own data)
-
- Expose / consume more web services
- More channels support for whole business sectors
- Increased visualisation 3D
-
- Demand from Govt to provide a configurable API to embed in
Business applications
SIX Viewer - Future plans 30.
- Increased exploitation ofvisualisationtechnologies
-
- 3D e.g. Google streetview
-
- Video display rather than static imagery
Future trends in web mapping 31.
- Location based services proliferation -
- Increased availability of web services (push/pull)
- New technology to empower users to extend their user experience
e.g. new cameras with geotag capacity
- Greaterempowermentof users to add & integrate location
information means that the future direction of web mapping is in
their hands
