based on satellite imagery?
imagery and what is changing.
data from satellite imagery?
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?
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 Spottitt service 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
Sputnik launched 4 Oct 1957 >1000 satellites >2000 satellites >3000 satellites From single satellites To constellations
Global coverage and resolution of data
IKONOS revisit 3-4 days 4 meters 1999 SPOT 1 revisit 1-4 days 20 meters 1986 Earth-i 3*per day <1 meter Colour video 2019 Geoeye-1 1.5 meters 2008 Landsat 1&2 18 days 80 meters 1972 Landsat 8 15 days 30 meters 2013 Sentinel 2 5-8 days 10 meters 2015
Similar picture for radar (SAR) satellite imagery
The buying process is complex and often very manual
can seamlessly search, purchase and download imagery straight into your systems
and download imagery from multiple commercial and non-commercial providers.
Commercial license agreements
Competition and technical advancements forcing change
Just an expensive picture?
Fully automated, cloud based, remote sensing analysis service, which allows customers to:
Turbine Positioning analysis
and get results in a matter of minutes/hours. “Quick, efficient, affordable. No earth observation knowledge or software required”.
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
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)
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)
AI used to find similar features all across America
Feature extraction - Building recognition analysis(Spottitt)
Neural network trained on broad catalogue of global building types
Forestry and agricultural insights (Global Surface Intelligence)
Machine learning combined with high performance processing
Site selection (Spottitt)
Multi input analysis of exclusion zones and buffers to determine suitable sites.
Monitoring and change detection - Deforestation
Time-lapse based on satellite imagery
Monitoring and change detection – Water depth (Proteus Geo)
Satellite derived bathymetry
Can Satellite Image Analysis Replace Manual Digitization? But………….it has an important role to play in the generation of valuable GIS products and services.
