• Why develop processes and services based on satellite imagery?
• Traditional barriers to using satellite imagery and what is changing.
• What is possible in-terms of creating GIS data from satellite imagery?
Agenda
For every 100MWatt of installed onshore wind power somebody has spent over 500,000 Euro and 6 months of manual effort just searching for sites with suitable geography using out of data maps and information.
Could automation and satellite imagery be used to reduce cost and time to market of onshore wind
developments?
Context
Thus in 2014 the concept of Automated and On Demand remote sensing analysis was born and 3 Spottitt co-founders started their journey.
Thanks to European Space Agency co-funding July 2017 pre-commercial trails of the Spottittservice started with 8 customers.
Lots has changed and is going to keep changing:
Satellites becoming smaller and therefore cheaper to build and launch
Single satellite to constellations
Global coverage with high revisit frequency (Video)
Competition driving pricing and product spec.Open source and inter commercial providers
Why consider satellite imagery?
Sputnik launched 4 Oct 1957
>1000 satellites >2000 satellites >3000 satellites
From single satellites
To constellations
Global coverage and resolution of data

Why consider satellite imagery?Similar picture for radar (SAR) satellite imagery
The buying process is complex and often very manual
Traditional barriers?
• Online portals for search/purchase/download of imagery
• Growing number of image providers have APIs so you can seamlessly search, purchase and download imagery straight into your systems
• Still only a few services where you can search, purchase and download imagery from multiple commercial and non-commercial providers.
Commercial license agreements
Traditional barriers?
Competition and technical advancements forcing change
• Relaxing of many areas
• Creative business models
Just an expensive picture?
Traditional barriers?
• Cloud computing
• Advanced image analysis techniques
• Automation
Fully automated, cloud based, remote sensing analysis service, which allows customers to:• select their desired automated analysis – ranging from Land Cover Analysis through to
Turbine Positioning analysis • define their area of interest any where in the world• purchase the most recent satellite imagery and data from multiple sources• input their analysis parameters of choice e.g. minimum distance from buildings, roads etc.
and get results in a matter of minutes/hours.
“Quick, efficient, affordable. No earth observation knowledge or software required”.
Spottitt Service
10s of centimetres
4-13 spectral bands
Pre-processing required
£0 – £14 per km2 (40cm achieve imagery)
Global coverage
High revisit frequency = low prob. tasking required
Satellite versus aerial photography ?
Centimetres
Typically 4 bands
Analysis ready
£0 - £35 per km2 (12.5 cm achieve imagery)
Regional/national coverage
Low revisit frequency = high prob. tasking required
Land Cover Analysis (Spottitt)
What is possible?
Complex rule based algorithms tailored to renewables sector which provide 6m resolution LCA’s anywhere in the world
Feature match – Wind turbines, storage tanks, (GeoVisual Search by Descartes Labs)
What is possible?
AI used to find similar features all across America
Feature extraction - Building recognition analysis(Spottitt)
What is possible?
Neural network trained on broad catalogue of global building types
Forestry and agricultural insights (Global Surface Intelligence)
What is possible?
Machine learning combined with high performance processing
Site selection (Spottitt)
What is possible?
Multi input analysis of exclusion zones and buffers to determine suitable sites.
Monitoring and change detection - Deforestation
What is possible?
