Congratulations to our Challenge winners!

Millie Smith

Geovation is excited to announce two amazing winners of the Diffuse Coastal Pollution Challenge in association with UKHO are GlobalTrust and Satsense Solutions!

Geovation’s Challenge with the UK Hydrographic Office (UKHO) launched to find a sustainable solution to tackle the problem of diffuse coastal pollution and the submissions definitely didn’t disappoint. The final Challenge pitches and winners’ event held at the Geovation hub in London, saw all 4 finalists Seaswirl, Global Trust, Satsense Solutions and UpDownstream pitch their ideas to an audience and judges. GlobalTrust and Satsense Solutions were subsequently named joint winners of the challenge for their impressive solutions!


GlobalTrust – Winner

GlobalTrust is a data analytics company using the power of satellites to guide organisations worldwide to develop and deliver sustainability strategies while embedding ethical practices into the future of decision making.

Their solution is based on using satellite data and a geo-temporal platform based on datacube architecture to identify environmental degradation and pollution in coastal areas connected to diffusive pollution factors. They will develop a machine learning algorithm, to identify the presence of anomalous activities, issuing subsequent alerts.
They will use the prize money to further refine their existing client facing dashboard and promote the activity using an interactive webinar and blog.

Estel Blay, Senior Business Development Manager of GlobalTrust said: “GlobalTrust is proud to be the winner of the latest Geovation Challenge. Our team worked hard to identify a present space-based innovative solution to tackle diffuse coastal pollution. The discussions with organisations such as the UK Hydrographic Office, Ordinance Survey and Geovation sparked new ideas for further development of our solution. We would like to thank the organisers and sponsors for their support and their belief in us.”


Satsense Solutions – Winner

Satsense Solutions is a UK based start-up that uses satellite remote sensing and geospatial analytics to provide business and governance solutions. The company is passionate about applying satellite earth observation to solve the challenges of sustainable development, resource management and climate change, and has successfully deployed commercial solutions for the Water Resources, Hydropower and Infrastructure sectors.

The proposed solution makes use of two key concepts, namely, Satellite-based Water Quality Assessment and a Watershed Approach; to identify problematic watersheds that contribute excessive amounts of sediment, nutrient and pollutant loads and suggests best land management practices to mitigate these discharges. Thereby helping to solve some of the major problems of diffuse coastal pollution in a targeted and cost-effective way.

Nikhil Pasari, Co-founder and Head of Business Development at Satsense Solutions, pitched at the live event and had the following to say “Winning the Geovation Challenge is a proud moment for Satsense Solutions. The recognition from Geovation, Ordnance Survey and the UK Hydrographic Office will help bring to life a valuable and sustainable solution to tackle the problems of diffuse coastal pollution. We look forward to forging relations with participants in the UK water sector to benefit the planet and people.”

The prize money will be used to further develop the company’s web based application (www.satsenseapp.co) to include automated data processing and additional features and functionality so as to enable scalability and provide users with deeper insights.


UpDownstream – Finalist

diffuse pollution finalists

UpDownstream are a small team of two, Elanor Gowland and Simon Barnfield who offered a solution of a fast light-weight modern web app using OS rivers network and water quality data to help local communities, schools and charities understand diffuse pollution issues relevant to them.


Seaswirl – Finalist

Seaswirl represented by Alexandra Groszek and Kaan Adem Ozdemir designed a spinning water filter powered by a solar panelled cone. This incorporates a reverse osmosis filter membrane, that traps water impurities as well as obtaining data on the types and amounts of impurities.

Diffuse Coastal Pollution Challenge

The Challenge focused on the sources, pathways and impact of diffuse pollution on our coastal regions and environments. Diffuse pollution comes from multiple sources that become a cumulative problem and is the main source of water quality degradation worldwide.

Applicants to the challenge had access to data from Ordnance Survey, UKHO, Met Office, and British Geological Survey and deep dive research to help them develop their solutions. Geovation ran a bootcamp with all the teams to assess their current ideas and help them to further develop them into feasible ideas.

Nikhil Pitching

All the pitches and solutions proposing excellent ideas, made judging the challenge no easy task of choosing the winners. On the panel was Mark Casey, Head of Research, Design and Innovation at UKHO, Charlie Draper, Business Change and Innovation at Ordnance Survey and Chris Parker, Founder of Geovation.

Carly Morris, Head of Geovation, said: “First of all, I’d like to thank all the finalists for providing tremendous pitches. It was a really difficult decision for everyone on the judging panel. At Geovation we believe that start-up solutions can have a positive impact on people and the planet, and this was encapsulated by all four finalists. I’m sure the prize money will help Satsense Solutions and GlobalTrust build on what they have already accomplished and continue to provide sustainable solutions to some of our biggest challenges.”

Mark Casey, Head of Research, Design and Innovation at UKHO said “I was really impressed with the innovative ideas the finalists had developed to tackle the problematic issue of diffuse coastal pollution. The teams had deployed the use of different data sets in varying ways in order to develop sound, sustainable solutions. I thoroughly enjoyed meeting all the finalists and hearing their pitches, subsequently I look forward to observing the teams as they continue to evolve their ideas and test out their solutions.”


Future Geovation Challenges

Geovation is already planning future challenges around the topic solving issues on our coasts including costal erosion and plastic pollution. Stay up to date with the upcoming challenges through the our website.
