Visualisation? Now, Its Possible

• Technology today is Better Faster Cheaper
• Readily available hardware and software
• Freely available run-time

5
A Point in Time

• Traditionally driven by Defence
• Games technology is now driving commodity
  hardware and software development
• Hardware pricing is plummeting
• Geospatial sciences (GIS, Remote Sensing,
  Photogrammetry) are perfect for a digital era
• The public is becoming more and more
  geospatially aware (thanks to apps such as
  Google Earth)

6
Specific Applications

• Public display community consultation
• Corridor selection/management/control of major
  engineering works
• Geographic Entry statements and First
  Impression designs
• Eye clutter, signage and other visual pollution
  management
• Surge tide and coastal inundation management
• Rural clearing, subdivision and riparian buffer
  management
• Disaster recovery/management/control
• Bushfire prevention strategies
• Route and corridor planning
• Infrastructure planning
• Line of sight surveys
• Internal communication
• Quick updates
• Asset management
• Archive (perhaps for later temporal analysis)

7
So, What IS Geospatial Visualisation Simulation?

• Real-time visualisation
• Out of the window aesthetics
• Interactive
• 3D
• Simulation-specific file format and structure

8
What Data is Required?

• Import data
• GIS data
• DEMs
• Orthophotos and/or Satellite Imagery
• 3D Models
• Textures

9
What Software is Required?

• In 2000 there were only 3 real commercial
  geospatial vis/sim packages
• Now there are many
• VizMAP uses and recommends TerraTools from
  TerraSim Inc.
• COTS
• Best of breed
• Supports defacto standards and formats

10
What About Hardware?

• Building the database
• COTS PC (even a laptop)
• Visualising the database
• COTS PC with OpenGL graphics card (Laptop?)
• SGI Onyx 3 graphics supercomputer
• Everything in between

11
How Does a Simulation Work?

• Tiling
• Levels of Detail (LoDs)
• Paging (TSG format)

12
How is a Simulation Made?
A simulation can be as simple
13
How is a Simulation Made?
or as complex as you like
14
Whats the Run-time?

• e.g. TSGFly from TerraSim Inc.
• Free distribution
• Real-time fly/drive/walk-through
• Interactive or stipulated flight paths
• Stipulated start/jump points
• Mouse operated
• up/down left/right forward/backward
  faster/slower
• Control
• Fog, Cloud, Time of Day, etc.
• Terrain hugging Fly over Walk through
• Measure
• Line of Sight
• Position
• Distance

Case Study 1Surat Energy Province

• Developed for NRM
• NRM provided aerial photography multimedia
• VizMAP sourced broadscale imagery and DEM
• Required to show potential investors the scope of
  the Surat Coal Basin and in particular, the
  requirement for a new rail link between Wondoan
  and Banana
• Time to complete 8 weeks

RunSurat

Case Study 2Gladstone Port Access Road

• Developed for MRD
• MRD provided aerial photography DEM DXF
  structures and engineering works and digital
  photography for eventual model textures
• VizMAP sourced broadscale imagery and DEM and
  modelled buildings and other infrastructure
• Required to show Council what was proposed and
  for use in public consultation
• Time to complete 6 weeks

Case Study 3New Coal Mine in Kalimantan

• Developed for PT Asmin Koalindo Tuhup (AKT)
• AKT provided DXF of mine 4 year plan lease
  boundary and road corridor
• VizMAP sourced broadscale imagery and DEM and
  modelled buildings and other infrastructure
• Required to show proposed coal mine and
  associated infrastructure in Central Kalimantan
  to potential Russian investors
• Time to complete 8 weeks

RunTuhup
19
Case Study 4Everest Base Camp Trek

• Developed for Centacare
• Centacare provided nothing
• VizMAP sourced broadscale imagery and DEM and
  modelled trek route
• Required to show trek from Lukla to the Everest
  Base Camp in Nepal for prospective trekkers
• Time to complete 1 week

RunEverest

Case Study 5New Pit at Cadia Valley

• Developed for Newcrest Mining Ltd
• Newcrest provided DXF of existing and proposed
  mine sites including open cut pits, tailings dams
  and waste dumps, as well as digital photography
  for model textures
• VizMAP sourced broadscale imagery and DEM and
  modelled buildings and other infrastructure
• Required for public consultation to show visual
  impact of proposed new pit
• Time to complete 6 weeks
