Presentation objectives

• Maps a history of mans use of geospatial
  information
• The digital age - the current approach to sharing
  digital geospatial information does it deliver
  the goods
• The e-Government Interoperability Framework
  (eGIF) - specifications for geospatial
  information currently
• Proof of the pudding geospatial information
  interoperability a working example between
  Central and Local Government

Ancient man lines on cave walls, pebbles in
desert sands

• Most human endeavour, at some stage, needs
  location information ( or intelligence )
• a basic requirement for survival, security,
  organising society, as well as for recreation
• This will always be true

4

• Mankind learnt long ago how to measure and
  represent local geospatial features
• Ancients applied basic geometry skills with great
  precision

5

• By the middle ages maps, charts and globes became
  indispensable tools for planning exploring the
  new world, finding resources, developing trade
  routes to new markets
• These were valued tools Crown jewels !
• One-off, precious, communication tools describing
  the known world. Providing strategic advantage.

• The printing press was revolutionary providing
  a way to duplicate and share the map or chart
  whenever it was deemed advantageous to do so
  eg with allies, partners
• A way to faithfully replicate the record of
  geography each map/chart identical to one
  another.

• Contemporary example of published official
  paper map or maritime navigation chart

• In the 1970s geographers discovered computers
• Copies of the map, become much easier to make
• An enormous effort began (internationally) trying
  to derive consensus on standards, open ways to
  effectively share digital geospatial data
• In NZ, we joined this effort

12
Computers a double edged sword

• Digital mapping driven by proprietary vendor
  specific software interoperability was
  difficult
• As applications moved to the desktop, much of the
  data followed
• ANYONE with the software could create geospatial
  data and did
• Data was copied, dispersed, amended and copied
• Data management became subservient to low-cost
  processing and hardware of client/server
• Silos of systems and information proliferate on
  every PC and every departmental server

Interoperability across the Whole of Government
Management staff in organisations across the
Whole of Government require access to
information

• When it is needed
• Where it is needed
• In the form needed
• With the quality and accuracy needed for ANY
  organisational purpose
• For everyone in the enterprises

15
Interoperability across the Whole of Government
So, the target business environment - dynamic
access to information within and between
organisations where

• Communication happens in Real-Time
• Coordination occurs in Real-Time
• Applications are in Real-Time
• Solutions are in Real-Time
• Decisions are in Real-Time

16
What if we could go back to the authoritative
source?

• Get back to everyone accessing the master map
• Like the single original on the cave wall
• or in the Kings safe
• to connect to the respected and trusted points of
  truth within organisations across the Whole of
  Government?

e-Government timing was good

• In 2000 the opportunity to rationalise access to
  geospatial information coincided with the
  introduction of the e-Government strategy
  join-up government
• Release 1.O of the NZ eGIF made provision for
  geospatial information interoperability

National topographical map launched online

• launched by the Minister of Lands in December
  2002
• This enabled experimentation on achieving
  interoperability using the WMS specification ?

• More than technology a Galileon shift
• Point of truth access to the master map
  (original) wide access to authoritative data
• Interoperability standards technology have
  matured and are enabling
• Proof of the Pudding LINZ / WCC
