Solution Looking for a Problem?• Transition between innovation and
compelling value, science to business
• Customer-centric rather than technology
• Current applications– Utilities, Heritage, Architecture, Planning and
Entertainment

Visual Impact Assessment (VIA)• Part of EIA (Environmental Impact
Analysis) – an assessment of the possible impacts resulting from development
• Visual impact is defined as a change in the appearance of the landscape as a result of development

Typical VIA Components• Viewshed / ZTV
– Map-based zones of theoretical visibility• Cross Section
– A-B line-of-sight assessment• Viewpoint
– Photomontage– Line diagram– Artistic impression
• Visualisation– Guide scale, location and design of wind farms– Used for more illustration

Call to Action – Mobilise!• Consider The End User
– GI Professional or Spatially-Poor Citizen• Consider The End Product
– It’s Not Always About the Map– Spatial Data is Just The Enabler
• Use New Technology Where Appropriate– Mobile, Sensors, 3D
• Seek Convergence and Adjacency
