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

Holographic Radar solves the problem

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
