Introduction
•Agenda
–Context & Background
–Geospatial Data in Planning & Visualisation
–The Role of Mobile Technology

Case Study
Planning and Visualisation
•Key Geospatial Users
•Maps are a Core Part of Legislation
•Online Services Developed Including:

Online Local Development Plans
GI –Data and Usage
•Data
–OS Background Mapping
–Aerial Photography
–DTMs
Data Issues: Communication
•Public Halls
–Limited Access
•Website

Limited Data
Data Issues: Physical & Technical
•Challenges for the Public
–Access & Interpretation
Typical VIA Components
•Viewshed/ ZTV
–Map-based zones of theoretical visibility
•Cross Section
–A-B line-of-sight assessment

Viewpoint
VIA Data Issues: Social
•Developer and Consultant Driven
–Lack of trust by implied partiality
–Historically manipulated images
–Viewpoints are restricted by cost
and practicality for photomontage
VIA Data Issues: Technical
•ZTV's are based on bare ground scenario
•Images are an instance of day/weather
•Static images do not show rotation
•Flicker/shadow effect not represented
Reconstructing the
visualisation
during
Supporting Research
•Photomontages are considered the most effective
visual representation in terms of impact of
development from specific locations but with
drawbacks listed as including
–lack of realism, static viewpoints, lack of animation,
weather dependant,
inflexible and expensive to manage

•Gartner 2013
–Hype Cycle for Emerging Technologies
What is GIality?
GIalityn.[jee-al-i-tee]
1.the convergence of geospatial data with
augmented reality technology
Finding a Place for AR
•Transition between innovation and
compelling value, science to business
•Becoming customer-centric rather than
technology
-
centric
Mobile Visualisation for VIA
•Modern Device Integration
–Imaging / Camera
–Location (GPS) and Mapping
–Magnetometer (Compass)

Accelerometer and Gyro
•Multiple Viewpoints
–Personal, Location, Democratised
•Animation of Digital Models

Turbines
and Wind Direction
Features and Advantages
•Major West Coast Development
–Public Consultation by Facilitating Change
Case Study
Sharing Geographic Data
•Limited by PDF
Visualisation Data Access
•Classic Map View
•Fly Through Overview
•Relocated View (Virtual Reality)
How Does it Work?
•Physical Devices
–Camera, Accelerometer, Magnetometer,
Gyroscope, Fusion API
–Apple iPad (4
th
Gen) / Retina

Google Nexus 10
How It Works (#2)
•Distributed Application Environment
–Apple iTunes, Google Play, Windows Store
•Cloud Services

HTTPS Administration Site
Issues and Futures
•Terrain Management
•Natural and Built Environmental
•Accuracy of Camera and Lens

Integration of Weather and Lighting
Summary
•Mobile Sensors including location,
attitude and imaging become de facto
•Augmented reality needs real-world
applications to evolve for business
