Monitoring Wildfires and Assessing Damage from Space

Rezatec’s geospatial data analytics service is helping foresters to salvage timber after devastating wildfires.

Not a day goes by without a wildfire burning in some part of the world. Fires are spreading across larger areas and burning more severely than ever before in modern times. Forest fires have occurred naturally for millions of years and play an important role in the long-term health of forest ecosystems; however, they also threaten lives and property, and leave many dying trees in their wake that act as kindling for yet more fires in the future.

Except for all but the most severely damaged, most trees can retain much of their commercial value directly after a fire. For the trees that survive, the resulting stress weakens them and makes them more vulnerable to disease, rot and moisture – meaning salvage is a very time-sensitive operation.

Satellite data analytics provide foresters with the information to locate, date and assess the extent of the damage accurately and quickly, allowing them to make informed and rapid salvage decisions.

Leading geospatial AI company, Rezatec, has produced a free guide ‘Assessing Forest Wildfire Damage from Space’ which outlines some of the key benefits of using satellite data to assess wildfire damage and plan salvage operations.

Tim Vallings, Vice President of Global Resources at Rezatec commented
 “With a complete and accurate picture of damage in hand, foresters are better prepared to make informed decisions on all timber salvage operations, resulting in both improved decision-making over which trees to salvage, and a higher resulting commercial return on salvage than would have otherwise been the case.”

Rezatec has produced a number of other guides relating to the application of satellite data for effective forest management including: Tree species identification form space and the early identification and mitigation of Spruce Beetle.

‘The Evolution of Earth Observation’ – Featuring Rezatec

The Evolution of Earth Observation’ published in this month’s Ingenia magazine (by the Royal Academy of Engineering) is a feature article exploring how satellite images are used to monitor changes in Earth’s natural and built environments, with applications in areas as diverse as land use, natural disasters and climate change.

The author, Science writer Tereza Pultarova, spoke to three industry leaders, including our very own COO Philip Briscoe, on how artificial intelligence is helping innovative companies such as Rezatec using satellite data to solve problems on Earth.

The article focuses on how Rezatec helped one of our clients, Portsmouth Water, which had witnessed rising nitrate levels in groundwater to understand more about the sources of this pollution.

Identifying Spruce Beetle infestations earlier using satellite data

Spruce Beetles have become an increasing threat to the forestry industry over recent decades. Outbreaks used to be episodic but are now at epidemic levels in many parts of the world.

Once an infestation is identified, it is a race against time to contain the outbreak and salvage affected timber before it loses its commercial value.

Rezatec, leading providers of geospatial data analytics for the forestry sector, have produced a guide: ‘Identify Spruce Beetle Infestations Earlier Using Satellite Data’, which examines how beetle infestation affects timber quality over time, the challenges of identifying infected trees using traditional methods, and how multi-spectral satellite data can help to identify affected stands before they lose much of their commercial value.

By assessing multi-spectral bands such as infra-red to measure more subtle indicators of plant health, infestation can be detected up to three months earlier than when using purely visual methods.

Tim Vallings, Vice President, Global Resources at Rezatec commented: “Identifying diseased trees as early as June allows foresters to validate, plan and fell in the same year, and thereby sell the timber as much as a year earlier than traditional methods allow to obtain a better market price.”

The key benefits of using satellite data to identify Spruce Beetle infestations are:

  • Regularly monitor subtle changes in tree health across entire forest
  • Identify outbreaks up to three months earlier
  • Salvage and sell timber up to one year earlier

Rezatec have produced a number of other guides relating to the application of satellite data for effective forest management including: tree species identification from space and a comparison of the benefits of satellite and lidar data for forestry analytics.

Rezatec provides AHDB with innovative geospatial data analytics to map true extent of potato crops across the UK.

Harwell, Oxfordshire, 2nd October 2018 – Rezatec, the leading provider of geospatial data analytics to the Infrastructure, Forestry and Agribusiness sectors, has been working with The Agriculture and Horticulture Development Board (AHDB), to demonstrate the effectiveness of using satellite data to map the extent of potato crops in pilot locations across England and Scotland.

AHDB is the UK’s statutory levy board funded by farmers, growers and others in the supply chain. Its purpose is to inspire farmers, growers and industry to succeed in a rapidly changing world. The assessment of innovative technologies that can enable its vision is an important focus for AHDB and this project aims to evaluate the use of satellite data.

Looking at four sites spread across the UK, Rezatec applied its proven crop identification techniques to map locations of potato crops, down to individual fields, some of which just a few hundred square meters in size. A crop health map was then generated to highlight the extent and abundance of each potato field. This enables AHDB to better understand production areas of potatoes in the UK from season to season at a micro level.

Rezatec applies its geospatial data techniques to extract specific spectral indices across the growth cycle to create a signature that identifies the crop, using both optical and radar satellite data sources. By applying its in-house machine learning algorithms to these indices, Rezatec can distinguish potato from other crop types with up to 95% accuracy.

Additionally, through active remote sensing monitoring, Rezatec can also assess variables of crop performance, e.g. health, against the crop model through the growing season, and, using its data science techniques provide growers with critical information to take corrective action and ultimately increase crop yields.

Dr Jim Dimmock, Resource Management Scientist at AHDB summarised: “It is evident from our collaboration with Rezatec that the application of satellite data for mapping crop extent is of great value and compared to more traditional methods, we were impressed by the ability to scale across large areas with high levels of accuracy.”

Dr Andrew Carrel, Chief Technology Officer at Rezatec commented: “Rezatec’s agriculture management services are very versatile, ranging from identifying crops at a field, and even sub-field level, and monitoring crop performance, up to macro-level analytics to support commodity crop trading for multiple end-users including Government and traders.”

Rezatec provides its agricultural management services around the world to a wide range of agricultural end-users from sugar cane and wheat farmers in Mexico to dairy farmers in the UK.

Tree species mapping from space – it’s revolutionary!

Whether you’re the owner of a small private woodland or a forestry company responsible for millions of acres, Rezatec have created a free, useful guide on identifying and mapping tree species distribution.

Understanding what tree species you have and where they are is critical for effective forest management and commercial decision-making. The ‘Earth Observation for Tree Species Mapping’ guide, available here, explores the common challenges of identifying species using traditional aerial technologies and how satellite data can be used to quickly, accurately and cost-effectively identify and map tree species distribution.

Tim Vallings, Vice President, Global Resources at Rezatec commented:  “It shows you what’s going on in the entire forest, not just small parts of it, giving you a complete and accurate picture of tree species and their location.”

Rezatec presents the data in an online portal which makes it easy to understand for any stakeholder as well as taking the risk out of commercial ventures and supporting informed business decisions.

Tree species identification from satellite data requires calibration plots of less than 1 per 100 acres. Compared to other methods, this represents a significant saving in operational time and money.

The key benefits of using satellite data in tree species mapping are:

  • Savings of up to 80% in operational expenditure,
  • Refreshes up to every week,
  • Tree species accuracy up to 90%

So far, Rezatec have mapped tree species distribution to meet a variety of requirements across an expanding list of locations around the world, including the UK, US, Europe, Canada and Australia. Their robust methodology enables an ever-growing number of species to be classified with 80 to 90% accuracy, supporting informed commercial decisions. Rezatec can apply confidence limits for risk assessment, and as a result can create data suitable for a range of users.

Mobile app helping Mexican farmers improve sugar cane and wheat yield through the analysis of satellite data

Rezatec has launched a new mobile application aimed at helping Mexican farmers improve crop productivity and stabilise their incomes to facilitate rural community economic development under the UK Space Agency’s International Partnership Programme (IPP).

Wheat farming in the Yaqui Valley is at the forefront of new technologies for wheat compared to other parts of the developing world, however, the area was hit by a fungal disease (Karnal bunt), and export profits suffered. The effect from droughts from 1996 to 2004, also contributed to an overall fall in income from agriculture in the Valley of 40%. Average wheat yields are currently around 6.2 tonnes per hectare, with considerable variability from year to year. Annual profits from wheat production in the Valley varied by 60% per tonne from 2009 to 2017, with a steady rise in the total cost of production over time. Better management practices by smallholder farmers for nitrogen application, irrigation and weeds would help to improve yields and productivity.

The sugarcane industry currently generates more than 930,000 direct jobs and employs another 2.2 million people indirectly, contributing a total of around US$2.5 billion a year to the Mexican economy. The average yield is currently close to 70 tonnes of cane per hectare however smallholder farmers have below average productivity partly because they have not adopted modern methods of agriculture. They are also threatened by drought (especially because of under-developed irrigation infrastructure), pests, disease and weeds.

The overall challenge for both the wheat & sugarcane sectors is to transform both traditional extensive as well as modern intensive systems into sustainable systems producing more crop output with better use of resources and this requires better management of the interacting parameters controlling yield.

In response to these challenges, Rezatec has now launched a free mobile application ‘COMPASS V1.0’ (Crop Observation, Management and Production Analysis Service System) aimed at helping wheat and sugarcane smallholder farmers in Mexico, benefit from using Earth Observation (EO) satellite data with in field measurements to reduce production costs and increase crop yields. The ultimate aim is to ensure that farmer incomes become more stable, and therefore directly benefit farming families and rural communities, as well as addressing potential environmental issues.

Mexican COMPASS, is a four-year project launched in December 2016 under the UK Space Agency’s lnternational Partnership Programme (IPP), which aims to address real issues faced by emerging economies using satellite solutions whose outputs lead to a measurable and sustainable economic or societal benefit.

Ray Fielding, Head of IPP stated that “The UK Space Agency is delighted to be working with Rezatec on the Mexican Crop Observation, Management and Production Analysis Service System (COMPASS) project under our lnternational Partnership Programme. The release of this application will provide decision support tools to help Mexican farmers and smallholders to improve their crop management of wheat and sugarcane so that income stability is improved, thereby providing economic and societal benefit.”

Under the project, Rezatec has partnered in the UK with the University of Nottingham, supported by Booker Tate, and in Mexico, with CIMMYT (International Maize & Wheat Improvement Center) and MASCAÑA sugarcane research group from COLPOS (Colegio De Postgraduados).

Andrew Carrel, Chief Technical Officer, Rezatec commented, “Rezatec is excited to be part of the UK Space Agency’s International Partnership Programme, contributing our Earth Observation and Data Science technology to enable positive social, economic and environmental change in Mexico. We look forward to building on the success of this project to help other farming communities around the world.”

The project aims to target at least 1,200 farmers in Mexico during the project, with initially 38 farmers currently engaged and providing invaluable field data via the new mobile app which will be freely available to farmers.  The app will provide a portal for farmers to submit crucial information about their farming activities (such as sowing date, crop type and irrigation) and in return receive free recommendations as to when to undertake such activities in the future to maximum yield, as well as yield predictions.

Javier, one of the wheat farmers currently using the mobile app. said “The COMPASS App v1.0 is going to help me have all the management information from my fields handy and having the app. In the future advising on an optimum irrigation schedule to maximise my yield will be a huge benefit”.

Recently, the project was presented to the Mexican Ministry of Agriculture – SAGARPA, SIAP and INIFAP – and received very positive feedback, as well as offers of support from Government bodies to potentially extend the initiative for wheat and sugarcane farmers nationwide.

The services developed in the project will be sustainable after the funding from the IPP programme ceases through a fee-based subscription model whereby commercial companies, processors, government agencies and crop insurance providers will pay for enhanced datasets, aggregated data and more detailed analysis than the basic free data which is made available to smallholders.

The proven Mexican COMPASS model will be extended to other developing countries growing wheat and sugar cane to increase the viability and returns from using earth observation data to support smallholder farmers.
