A new thermal sensor fitted to survey aircraft is set to revolutionise the way local councils tackle energy inefficiency and fuel poverty in Britain’s towns and cities. Part of a new generation thermal mapping system unveiled by aerial survey company Bluesky, the system captures and maps highly accurate measurements of heat-loss from buildings.

The system includes a state-of-the-art thermal survey camera, advanced navigation and positioning system and improved sensor control and user interface. Older systems use instruments originally designed for use in a laboratory or industrial plant environment, but Bluesky’s new sensor has been specifically designed for airborne surveying and provides higher precision results.

Conventional systems require continuous cooling of the camera environment and this can lead to variations in results and subsequent issues during post survey analysis over large geographical areas. The Bluesky ‘microbolometer’ thermal camera can perform nearer to the real ambient temperature around the camera making it more suitable for use in aircraft flying at night.

“We are delighted to be the first to market with this superior thermal mapping system – it is the only fully integrated geospatial thermal infrared system in use in the UK,” commented Rachel Tidmarsh Managing Director of Bluesky International. “It will enable us to significantly improve the accuracy and efficiency of data capture. This will in turn benefit organisations such as Local Authorities and environmental consultants that are trying to reduce carbon emissions through more targeted and therefore effective energy efficiency campaigns.”

As well as being designed to operate under conditions of rapidly changing ambient temperature, the Bluesky sensor is also capable of measuring within the optimal spectral range required to assess the emissivity from building roofs. The sensor has a spectral range of 1.5-14 µm (1µm = 1 millionth of metre), a temperature range of -40ºC to +120ºC and a camera resolution of 1240 x 480 pixels. Combined with an advanced navigation and positioning system that allows geo-referencing of the resulting heat-loss image to a high degree of accuracy, allowing Bluesky to offer an unrivalled thermal mapping service.

“This is just another step in our commitment to capture and deliver the most accurate and up to date property level heat-loss map data,” continued Tidmarsh. “We pride ourselves on our track record and our team of vastly experienced reconnaissance, flight planners and post survey analysts ensured we achieved complete fulfilment of last winters surveys totalling in excess of 2000 sqkm including many towns and districts across the UK.”

Aerial mapping company Bluesky is helping to fund an exciting environmental project in Peterborough, promoting sustainable lifestyles and raising awareness of environmental issues through practical demonstration and community involvement. The Green Backyard project is set to benefit from the donation following a thermal aerial survey completed by Bluesky on behalf of Peterborough City Council. As active supporters of The Green Backyard the city council approached Bluesky to see how they could compensate for the greenhouse gases emitted as a result of the survey and Bluesky were happy to make the donation to the local community growing project.

Bluesky conducted the cutting edge thermal survey in April of this year capturing property level heat loss imagery for the city of Peterborough and its urban suburbs. The council will use the digital image map in its geographical information system (GIS), in conjunction with Ordnance Survey mapping and the council’s centralised address database (the Local Land and Property Gazetteer / LLPG), to help identify communities to target with awareness campaigns promoting energy efficiency measures. The data will also play an important role on the newly revamped council website where local residents can simply enter their postcode and house number to get a personalised ‘score’ for their property together with advice on improvements in insulation, energy efficiency and reducing consumption.

“As a city Peterborough is very proactive when it comes to environmental issues. In fact we are campaigning to become the UK’s Environment Capital,” commented Jenna Hiley, climate change officer at Peterborough City Council. “Even though it was important for us to map heat loss across the city we were conscious of the emissions generated by the survey aircraft and we wanted to do something meaningful for the local community.”

“The generous donation made by Bluesky, more than twice the recommended amount per tonne of CO2, will be used by The Green Back Yard project to fund some mature fruit bushes for the site on London Road,” continued Hiley.

Rachel Tidmarsh, Managing Director of Bluesky commented “Thermal imagery is an important tool helping councils identify households, businesses and even public sector buildings that could benefit from advice, grants or support to reduce energy waste and consumption. Although we already contribute to a carbon offsetting programme we were happy to support this project which is helping change the urban environment in Peterborough.”

Bluesky offer an end to end thermal data solution, including a cost effective airborne survey service measuring building roof heat loss levels across an entire city in just one evening plus a bespoke thermal mapping service creating intelligent energy consumption and fuel poverty maps to support energy strategies and local campaigns. Bluesky are also able to provide an easy to use software package, HELIOS, which helps councils analyse complex data from multiple sources and share results with colleagues, partner organisations and members of the public.

Coalville, Leicestershire, UK, November 2009 – Dorset’s A35 and C6 roads form a crucial link down to the county’s south coast. With a view of improving this link and therefore relieving seasonal congestion on over-capacity neighbouring routes, Dorset County Council has commissioned multidisciplinary engineering consultancy Buro Happold to prepare a feasibility study into bypass options for the village of Bere Regis.

In order to accurately understand the levels and features of the local terrain, the consultancy has used UK specialist Bluesky’s 3D map system which creates digital maps captured by aircraft mounted lasers. Bluesky have also supplied high resolution aerial photography that has been used to create 3D fly-throughs and visualisations of the resulting designs. 

Using 12d Model, a powerful terrain modelling and civil engineering software package, Buro Happold has expanded on an earlier feasibility study and prepared three options for the bypass. The detailed terrain model has allowed the designers to minimise any impact on the environment, particularly the associated costs of cut and fill operations.

“The size of the study area meant a traditional topographic survey was simply not feasible due to cost implications,” commented Neil Harvey, Senior Engineer in Buro Happold’s Highways and Infrastructure division. “However for the same price as a relatively small ground survey we were able to acquire very accurate terrain measurements and high resolution aerial photography of the entire study area. These have proved instrumental in progressing the feasibility study and preparing designs for each of the three options. The aerial photography will also be fundamental in communicating these designs during a future public consultation period as they provide real world detail to our computer generated models.”   

In order to capture the highly accurate LiDAR (Light Detection and Ranging) data a survey aircraft equipped with a system of lasers was used. Lasers were beamed to the surface and the time taken for the beam to be bounced back to aircraft-mounted receivers was recorded. Using the known position of the aircraft (derived from on-board satellite positioning equipment), the time taken for the return of the laser beam and the known value of the speed of light; the distance between the aircraft and ground is calculated. Additional readings can also be taken to determine the height of buildings, vegetation and other surface structures.

The Bluesky LiDAR data forms part of a detailed 3D terrain map, which is available online, that covers most of England and Wales including all major urban centres, coastal areas and flood plains. Aerial photography for the whole of England, Wales and parts of Scotland is also available to view and purchase online.

Leicestershire, UK, November 2009 – Aerial survey specialist Bluesky has launched new digital map layer accurately modelling the location and extent of trees and their proximity to buildings. Designed as a tool to help with the management of trees including maintenance, conservation and the issuing of tree preservation orders (TPOs) by local authorities, ProximiTREE details the exact spatial location and height of individual trees together with the circumference of its canopy; from this information a determination can be made of the root extent and therefore the potential impact on either existing or proposed properties.

Trees and hedges are fundamental elements of our countryside, however they also have a major part to play in urban areas. Trees and hedges in private gardens, parks and other open spaces, or lining the sides of  streets, railways, rivers and canals are of great importance, particularly in residential areas. They can provide valuable habitats for wildlife, improve the air we breathe, and help to conserve energy in nearby buildings. It is therefore essential that this valuable resource is effectively managed and protected.

However concern about the location of trees can be a major worry, not only when trees cause damage through subsidence but also because the proximity of trees can jeopardise house purchases, insurance claims, planning applications, mortgage loans and even cause disputes between neighbours.

“ProximiTREE is designed to provide an easy-to-use reference base for all decisions relating to the location of trees including their proximity to either existing or proposed developments,” commented James Eddy, Technical Director at Bluesky. “Derived from the most detailed and up-to-date aerial photography it is suitable for use by property developers, local authority users and insurance companies in fact any one involved in the ownership, management or development of property close to trees.”

ProximiTREE is derived from the most accurate and up to date aerial photography. Using overlapping images the exact location of every tree can be mapped and the height and extent of its canopy derived. ProximiTREE is suitable for use in most desktop Geographical Information Systems (GIS), web mapping applications and Computer Aided Design (CAD) packages. Both 2D and 3D versions of the map are available and ProximiTREE works alongside existing Bluesky datasets such as 3D buildings, terrain models and aerial imagery.

Leicestershire, UK, 05 November 2009 – Homeowners in West Yorkshire, UK, will soon be able to go online to see the heat loss from their property.  Following airborne surveys by aerial mapping firm Bluesky, the property level thermal map together with high-resolution aerial photography are to be provided online by Calderdale Council.  The council’s re-launched Calderdale Maps Online service will offer interactive maps together with new features such as address look ups and find my nearest.

The first phase of the relaunch will be the property level heat loss map created by Bluesky following a thermal aerial survey in March 2009. The interactive map will allow visitors to the website to check the thermal efficiency of their home or business property and then access further web pages detailing what measures can be taken to reduce heat loss.  In the case of homeowners, how they can apply for free or discounted loft and cavity wall insulation. Visitors to the site can also choose to view the data in an accessible way through an address look up form that returns property specific heat loss information in a text friendly format.

The latest online evolution is designed to allow the customer greater flexibility in terms of self service and the use of good quality geographic information was seen as fundamental to its take up and success. “The aim of the thermal survey and online map created by Bluesky is to raise awareness of energy efficiency amongst the householders and business owners of Calderdale and to encourage householders to have their property insulated,” commented Debbie Chew of the Environmental Management Team.

The thermal efficiency information is also being made available internally via the Council’s intranet mapping tool giving officers across the organisation access to the data. “In a more strategic channel the Corporate GIS Team will be working with the Private Sector Housing Team to analyse the data and target areas of the district where insulation is most required,” added Craig Moulding, Corporate GIS Manager.

The second phase of the online project will be the full transposition of information from the Council’s existing mapping portal to a new web application. Utilising the latest technology, interactive maps will be embedded within pages across the site providing visitors with access to a plethora of council datasets such as conservation and heritage, public rights of way and environmental and planning issues. The chosen data can be viewed with either Ordnance Survey mapping or Bluesky’s high resolution, 2009 aerial photography as a background.

Calderdale are long-term users of aerial photography pioneering in their deployment of the information rich resource by the Internet and Council Intranet. This has encouraged the use of data which in turn has established aerial photography as an essential tool in many departments, for example within the planning enforcement process. “As well as helping to build a picture of a site, and its changes over a period of time, aerial photography has been used on countless occasions to prove or disprove the existence of a development or change of land use. This is particularly important as development becomes immune from planning enforcement action after a certain period of time,” commented Robert Rose of the Planning Enforcement Team.

Leicestershire, UK, 02 November 2009 – James Eddy, Technical Director of aerial survey company Bluesky, has been appointed Chairman of a steering group providing advice and guidance to G-STEP a University of Leicester service designed to maximise the use of satellite imagery by businesses.

G-STEP (Global Monitoring for Environment and Security (GMES) – Space Technology Exchange Partnership) will build on the work of the flagship, multi billion euro European Commission / European Space Agency programme GMES. The role of G-STEP is to work in partnership with businesses to support them in the pioneering use and development of Earth Observation data projects.

“With the establishment of G-STEP some of the biggest barriers to the wider use of satellite data in the UK have been addressed. Namely knowledge, ease of access and relevance to business operation,” commented Adam Edwards, G-STEP Business Manager. “Earth Observation technology is currently under exploited yet has the potential to revolutionise business in a similar manner to the information technology expansion.”

“Bluesky are expected to be one of the pioneering businesses highlighting the potential of Earth Observation data and technologies and James is providing valuable insights as to how G-STEP needs to position itself to develop the market,” continued Edwards.

“This appointment is a real honour,” added James Eddy. “Earth Observation data is not just about expensive satellites orbiting the earth it also covers data from aircraft and ground observations too. With more than 20 years experience developing and maximising the use of remotely sensed data I hope that I can help other businesses derive value and benefit from its exploitation.”

G-STEP draws on the substantial expertise and knowledge base established within the University of Leicester’s wide-ranging scientific programme in Earth Observation (EO) which already has strong connections to GMES. It will also draw strategic partners, such as Bluesky, into the knowledge-exchange hub to provide immediate access to a broad range of applications for non-EO and EO specialist companies.

G-STEP can broker existing solutions through its extensive knowledge of the EO data, information and commercial industry contacts. It can provide partnership, as appropriate, to develop new EO solutions for customer needs. It can also set up collaborative projects with some seed funding for new developments for downstream products and services or innovative new applications.

Coalville, Leicestershire, UK, October 2009 - Aerial survey company Bluesky has launched an easy-to-use property heat loss mapper to help Local Authorities view thermal data which is collected during airborne thermal imaging surveys.  The HELIOS (Heat Loss Investigation System) web based reporting tool, developed by Manchester Geomatics, will help energy and environment teams understand the results of thermal surveys and allow cross referencing of data with other information.

With fuel poverty and energy consumption high on both the political and personal agenda, HELIOS allows survey results to be presented in a visually appealing and easily understandable manner.  HELIOS is designed to manage multiple data types enabling the cross referencing of thermal mapping with geo-demographic data such as Census information, building classification mapping and land use.  It also matches address information including the National Land and Property Gazetteer (NLPG), base mapping from Ordnance Survey, and other custom data layers such as the energy consumption compiled by BERR.

This powerful combination of information will help Local Authorities identify opportunities to engage with residents and the business community about suitable insulation grants, consumption advice and renewable energy products thus helping to measure and report on National Indicators and Performance Targets. 

“Fuel consumption and energy efficiency are ‘hot’ topics impacting not only on the environment but on the purse of every business, household and individual,” commented Rachel Tidmarsh, Managing Director of Bluesky. “By providing Local Authorities with up-to-date, building level thermal imagery plus the tools they need to analyse and communicate this information rich resource we can help reduce consumption, protect at risk residents and preserve the environment.” 

The end-to-end solution offered by Bluesky to Local Authorities includes a cost effective airborne thermal survey service measuring building roof heat loss levels across an entire city in just one evening plus a bespoke thermal mapping service creating intelligent energy consumption and fuel poverty maps to support energy strategies and local campaigns. By using HELIOS, Councils can now easily analyse complex data from multiple sources and share results with colleagues, partner organisations and members of the public. Bluesky has many years of successfully delivering thermal survey solutions to Local Authorities and help assemble, host and manage a HELIOS installation on behalf of an organisation.

Computer generated 3D visualisations are being used to assess the environmental impact of a proposed redevelopment at one of Britain’s industrial landmarks in the north of England. Environmental and engineering consultancy URS Corporation is using digital terrain data from Bluesky to help complete the planning for the major redevelopment project.  The Bluesky Digital Surface Model (DSM) will be used to generate a Zone of Visual Influence for Landscape and Visual Impact Assessment.

Due to the location of the proposed development, it was essential that the source data was as up-to-date as possible and included recently upgraded motorways and intersections.  Bluesky was able to offer URS a range of solutions, including NEXTMap height data, a fantastic cost effective product, a LiDAR (Light Detection and Ranging) survey or their own off-the-shelf 3D model. “It soon became apparent, during early discussions, that Bluesky’s own GeoPerspectives data was the only commercially available height dataset which included the specific section of the upgraded A1(M) that was critical for this project,” commented Ben Stephenson, Environmental Consultant URS Corporation Ltd.

URS selected the data for use within an Environmental Impact Assessment (EIA) on behalf of one of their clients. An EIA is a multi-stage process that considers the environmental effects of development proposals during demolition, site preparation, construction and operational phases and proposes ways to eliminate, reduce or mitigate any significant adverse effects on the environment.

Once submitted to the relevant planning authority the EIA documents are critically evaluated, and if necessary, further information is sought from the applicant in order to ensure the authority has sufficiently reliable information to understand the likely environmental effects and proposed mitigation measures before the planning application is determined.

The Bluesky DSM data supplied to URS Corp for this study is part of the GeoPerspectives product range, which offers nationwide coverage of highly accurate, photogrammetrically derived Digital Terrain Models (the earth’s surface excluding buildings and vegetation) and Digital Surface Models (the earth’s surface including buildings and vegetation). Bluesky is also able to provide ultra detailed LiDAR (Light Detection and Ranging) data and services covering the majority of England and Wales including all major urban centres, coastal areas and flood plains.

High-resolution aerial photography and colour infrared imagery supplied by Bluesky is being used to help preserve Britain’s hedgerows.  In a pioneering new development by Environment Systems - a geographic and environmental information consultancy - hedgerow features are being mapped automatically from the image data, considerably reducing the time and cost involved in more traditional field mapping exercises.

Hedgerows are a highly valued resource, but receive little protection under planning and environmental regulations.  As a result there has been a huge loss of hedgerows over the last 50 years. Hedgerows are a respected part of our cultural heritage and historic record, essential for marking ownership boundaries and controlling the movement of livestock, however with the availability of accurate maps, GPS and fencing these reasons are now less valid. In today’s world hedgerows are becoming increasingly important for their great value to wildlife and the natural landscape.  They also play an important role in preventing soil loss, reducing pollution, and for their potential to regulate water supply and reduce flooding. 

For a major habitat and environmental resource there is no exact record of the extent of hedgerows in Britain, and such data is prohibitively expensive to provide by field survey. Environment Systems, using the Bluesky data, has developed a semi-automated methodology for hedgerow mapping. The red, green, blue and colour infrared spectral bands of the imagery are optimised and automated digitising techniques are used to extract hedgerow features. The output from this process is a geographic information system (GIS) ready polygon hedgerow dataset complete with length, areas and condition indicator attributes.

“The key driver for this research has been to develop a rapid, low cost approach, requiring little operator interaction, to produce a hedgerow baseline that identifies the presence and extent of hedgerows over large areas,” commented Steve Keyworth, Director of Aberystwyth based Environment Systems Ltd. “The Bluesky data is ideal for this as it provides the key input; four band digital imagery, at a sufficiently high resolution with the most up to date coverage.” Environment Systems has seen considerable interest from local authorities and government organisations, keen to produce a cost-effective record of this important habitat and landscape resource.

The data supplied by Bluesky for this development project is part of the GeoPerspectives product range, which offers nationwide coverage of high resolution, up to date aerial photography and CIR imagery, photogrammetrically derived Digital Terrain Models (the earth’s surface excluding buildings and vegetation) and Digital Surface Models (the earth’s surface including buildings and vegetation). Bluesky is also able to provide ultra detailed LiDAR (Light Detection and Ranging) data and services and a Thermal Survey capability. GeoPerspectives data is available to purchase online at www.bluesky-world.com.
