The bigger picture …

“… out-going Government Chief Scientist
warns of floods, droughts and storms ...”
Actually much more than this:
• Growth in population – 1Billion in the next 12 years
• Development of cities
• … and the impacts of climate change
Professor Sir John Beddington

Smart services to transform
the efficiency and
sustainability of communities,
leading to reduction in service
costs and carbon emissions,
improving the quality of life for
all.
“Everything that happens in
the world has to happen
somewhere.” Hugh Abbott, The
Thick of It

BIM meets geospatial
• BIM meets geospatial
o Are these things really incompatible? ….
o … we used to talk of CAD and GIS in the same way.
• … but for the meantime I want to explore the geospatial
connection in three different ways – how does geospatial serve
to integrate our nation’s infrastructure?
o Visualising the appearance of new places
o Mapping a sense of place
o Modelling a sense of function
![Page 10: Making Infrastructure Work: BIM Meets Geospatial (Rollo Home, Ordnance Survey)](https://reader034.fdocuments.in/reader034/viewer/2022052301/554fb5dab4c9057b298b53e2/html5/thumbnails/10.jpg)
The basic data requirements
• Data must be consistent
• Data must model the real world – not simply map it or allow
visualisation. The demand is for data that supports modelling of
processes
• Data should be authoritative – to a readily available specification
• Features in the real world must be identifiable
• Data must be maintainable and maintained

3D - Two centuries of learned behaviour…
We carefully survey
urban landscapes and
model them in 2D…
…for users to apply this
2D data to help make
decisions which are
inherently 3-dimensional.

What do we mean by ‘analytical 3D’?
Application level Description Example
1: Pure visual Getting a sense of place or
navigating to a destination
A fly-through or personal routing
display (e.g. web search giants)
2: Visual-
analytical
Making judgements or decisions,
informed by visual information
provided by 3D.
Viewing a planned development from
different perspectives to see how it
would impact on views of a city
3: Propagation
analysis
Using 3D-based algorithms to
analyse phenomena such as
visibility, shade, noise or airborne
pollution
Running a viewshed or noise
mapping analysis
4: Topological
analysis
Querying the model in terms of
spatial relationships
Querying all roads less than 30m
from buildings with a volume greater
than 5000 cu m
5: Database
analysis
Using identifiers to relate the 3D
model to associated datasets
Querying the ownership status of
buildings with roof suitable for solar
power generation

"What we are trying to do is take all of the information that we as a
city collect on a day-to-day basis... and synthesise it to do
something useful."

Aggregating information and exploiting proximity
• Query in a GIS environment aggregating COBie product information for
geographic areas (how many elevators need to be serviced in the South-East within the next quarter?)
• Query in a BIM environment finding similar/related products nearby
(list all items by the same manufacturer within a 20 mile radius)

National initiatives - data sharing and interoperability
We have good experiences to build on:
• “DNF is an industry standard for the sharing and integration of business and geographic information from multiple sources.”
• “The Atlantis Initiative seeks to provide
better integrated geographical and environmental information to support decisions on flooding.”

Smart services to transform the
efficiency and sustainability of
communities ……. improving the
quality of life for all
Requires a change from simply
mapping place to creating a
model that supports the
modelling of environmental
and social processes.

From mapping place to enabling the underpinning DNA of a city
created by BIM to be exposed and connected to the geographic
features that control process and function in the landscape …
… we’re well beyond geospatial being relevant to BIM …
… we must not miss the opportunity to ensure that data created to
underpin new infrastructure in the next decade is immediately wired
into to the ecosystems of tomorrow’s smart(er) communities
… a significant proportion of our effort should be focussing on
making sure that our nation’s infrastructure is a truly integrated asset
In summary
