3. Introduction
3
 Data integrity – more than x;y;z and much more than cartography
 Data value within the organisation
 Right application of technologies
 Value in mapping assets correctly
 Why getting it right is so important
 Why addressing is critical
 More than vector and raster – the many D’s
 The role GIS plays in projects, BIM and other sectors

4. What is geospatial analysis?
4
 Gathering, displaying and
manipulating spatial data
 Data includes aerial imagery, GPS
data, 3D point cloud, historical
mapping, terrain data, demographic
and economic data etc
 Uses coordinates, street addresses,
post codes and other identifiers to
create models
 Models incl. maps, graphs, stats etc
 Data visualisations that simplify complex relationships to make them understandable
 Reveal changes and predict what is going to happen

5. Geospatial analysis
5
 Geospatial analysis adds more context
with addition of timing and location
information
 Show changes over time, what and
where changes are taking place
 Easier for the eye to recognise
patterns previously buried in
spreadsheets e.g. distance, proximity,
contiguity and affiliation
 IoT location sensors, mobile devices
and social media allow collection of
time AND place (geo-referenced)
almost any thing or event

6. What is a Smart City?
6
A smart city is an urban development vision to integrate multiple information and
communication technology (ICT) and Internet of things (IoT) solutions in a secure
fashion to manage a city's assets – the city's assets include, but are not limited to, local
departments' information systems, schools, libraries, transportation systems, hospitals,
power plants, water supply networks, waste management, law enforcement, and other
community services.
The goal of building a smart city is to improve quality of life by using urban
informatics and technology to improve the efficiency of services and meet residents'
needs.
ICT allows city officials to interact directly with the community and the city infrastructure
and to monitor what is happening in the city, how the city is evolving, and how to enable
a better quality of life.
Through the use of sensors integrated with real-time monitoring systems, data are
collected from citizens and devices – then processed and analysed. The information and
knowledge gathered are keys to tackling inefficiency.
Sectors that have been developing smart city technology include government services,
transport and traffic management, energy, health care, water, innovative urban
agriculture and waste management.

Building Information Modelling (BIM)
What is BIM?
BIM is a process for capturing, creating and managing all of the
information about a asset throughout its lifecycle.
Simply put…
Shared knowledge
resource of digital
information
Platform for true
collaboration
Faster, better informed
decision making
Many Governments are
mandating it to reduce
time, cost & carbon

The value in spatial information
 What will this data be used for? By whom?
 What important operational/economical/business decisions depend
on this information?
 How important is accuracy to me?
 How much time do I have?
 Do I really understand what I’m doing or do I want it to be simple?
 Being able to share this information and look back over time will
help me do a better job?
 What is my budget?

10. 1010
 Positional accuracy (or quantitative accuracy)
 Spatial in nature
 Horizontal (distance from true location), vertical (distance from true height) and
temporal (difference from actual time and/or date)

Leica Zeno GIS
Accuracy has four legs
 Attribute accuracy or consistency
 Validity by nature
 A feature in GIS is what it what it is on the ground e.g. a road on the map is a
road on the ground; a soil sample agrees with the type mapped; a planted
species is what is says in the plan

Leica Zeno GIS
Accuracy has four legs
 Completeness
 Reliability by nature
 Is everything the map claims to include in fact there
 E.g. when does the road become a track

13. 1313
 Logical consistency
 Non-spatial
 Data from one area is 2001 while another is 2003
 Use of different criteria or technique
 Spatial
 Data gaps or incompleteness
 Poor topological relationships

 How accurate do I need to be?
 2-5m
 Asset validation
 Location of buildings
 Sub-meter
 Land Management
 Area calculation
 Street furniture
 Disaster Management
 Infrastructure
 Decimeter / Centimeter
 Critical infrastructure
 Small assets e.g. manholes

17. Unlocking the value of BIM
Building Information Modelling (BIM) has the
potential to become the biggest step change in
the way the construction industry operates
within the built environment since the
industrial revolution – promising major
benefits in terms of cost, accuracy and time to
build.

25. So why does this matter?
26
 Geospatial analysis brings GIS – the
system of record for maps, and ERP
– the system of record for business
data, closer together
 Combination of geospatial data –
imagery, point cloud, design, GPS,
historical, vector and terrain etc. with
data from sensors and assets, and
the Internet of Things
 With business data from operations, customers, finance and marketing
 Models incl. maps, graphs, stats etc.
 Powerful combination of data that has not been visible AND as accessible before
 Treasure map showing you where new business opportunities, cost savings and
partnerships are or could be

26. The ‘spatial enterprise’
27
 Asset intensive industries – energy, transportation, public sector
 Ability to visualise business objects on maps is critical to improving efficiency and decision
making
 Organisations can streamline processing of enterprise AND spatial data – greater location
awareness across business processes
 Track devices when they enter, leave or stay in defined areas
 World events that will impact on operations – political and weather to take decisive action
 Resolve boundary issues ‘Where do we dig?’, ‘Where are the zone boundaries?’, What
underground lines exist here?’, ‘How close are they to buildings, people and other assets?’
 Instantly visualise routing scenarios
 Approx. 80% of enterprises have location data
 Use this to model competitor, customers and economic to make an informed new business
decision
