Realising the Value of Spatial Analysis
ESRI USER CONFERENCE 2014
Presented by John Allan & Ben Tilley

Who are we?
2
 A spin off company from Cambridge
Consultants Ltd
 Developers of a high precision, three
dimensional surveillance radar called
Holographic RadarTM
 We are solving the problems of wind turbine
interference on Air Traffic Control radar
(amongst other things!)

What is the problem?
3
 Wind Turbines interfere with Air Traffic Control
Radar
 Wind Farms can create “no-go” areas around
airports – not good for business or for safety!
 To meet UK Government renewable energy
targets for 2020, the problem has to be solved
 According to industry body RenewableUK, more than half of UK wind farm applications are
subject to objections from the aviation sector, mainly over issues relating to radar interference.
 RenewableUK is still analysing the latest research for 2013 applications, but preliminary results
suggest that 4-5GW of onshore wind and 7-8GW of offshore could be freed from the pipeline if
all aviation issues could be immediately resolved.

Why is it a problem?
4
 Traditional surveillance radars rely on a
rotating antenna
 They tell you “something” is out there,
but very inaccurately and once every four
seconds

Why so inaccurate?
5
 Traditional radars measure the
distance and bearing of the return
from the radar
 Slant range error introduces
locational errors

The Wind Farm Industry…
8
 Currently in the UK
– 720 onshore wind projects in planning
– 866 wind projects consented
– 788 wind projects refused
 50% refused due to aviation interference
 Complex planning process
 Suitable areas for large scale onshore wind
developments diminishing

Unlocking Potential Areas for Development
9
 133 radar sites located across the UK & Ireland
 Statutory Objection Zone around radar sites
allows stakeholders to object to any developments
within 35km
 Mitigation in these areas could free up over
70,000 square miles of land for development in
the UK & Ireland

Our Key Goal
10
“To identify wind farm developments in the planning phase, which are likely to or have an
objection from an Airport Navigation Service Provider due to the adverse effect the turbines
would have on their radar.”

Spatially UNaware – Achieving our goal Pre-ArcGIS
11
 Business opportunities identified by
─ Trawling the web
─ Industry newsletters
─ Direct contact with developers
 Low rate of success moving forward
after lead identification
 Time consuming
 Difficult to understand the scale of
problem
 Not confidence building in the eyes of
customers

Our GIS Solution…
12
1. Identify
2. Predict
3. Solve

RenewableUK wind farm database:
 Contains 3700+ records with details of:
– Planning status (Scoping, Refused
etc.)
– Project power capacity
– Application date
– BNG Eastings, Northings etc.
 Downloaded monthly in .csv format
Where do we get our data from?

Utilising ArcGIS to make sense of the data…
14
 Using ‘Definition Query’ within ArcMap to display
relevant wind farms based on the following criteria:
– In the planning phase
– NOT operational or under construction
– Large enough to financially support the costs
of radar mitigation
 Helps to narrow search very early on by applying
simple criteria
“The goal is to turn data into
information, and information into
insight.” - Carly Fiorina Former CEO of HP

Narrowing the search area…
15
 We need to identify:
– Developments which are likely to have
an aviation objection
– Key areas where radar mitigation is
needed

The ‘One to Many’ Approach…
16
 Why?
– Airports hold the key to consenting wind farm projects that interfere with radar
– To identify airports with the greatest business potential; i.e. projects with largest power output
capacity
– Opens up discussions for a complete, airport-based wind farm mitigation solution. One Holographic
RadarTM seeing many wind farms means multiple revenue streams
 How?
– By using ‘Spatial Join’ to summarise wind farms and their characteristic around all radar(s)/airport(s)
depending on their location, in this case, within the 35km Statutory Objection Zone

Not seen, no objection.
17

Predicting Radar Coverage Using ArcGIS Spatial Analyst…
18
 Why?
– In most cases, an airport will object to a wind
farm development if the turbines are visible to
their radar. We need to know which ones
these are.
 How?
– OS Terrain 50 DTM free dataset
– Visibility’ tool in Spatial Analyst, we can:
– Height of radar above ground
(Observer offset)
– Height of wind turbine (Surface offset)
– Earth’s curvature
– Radio wave refraction coefficient
correction
