2 Agenda 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?

3 Context 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.

4 Why consider satellite imagery? 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) From single Competition satellitesdriving pricing and product spec. Open source and inter commercial providers To constellations Sputnik launched 4 Oct 1957 >1000 satellites >2000 satellites >3000 satellites

5 Why consider satellite imagery? Global coverage and resolution of data SPOT 1 revisit 1-4 days 20 meters 1986 IKONOS revisit 3-4 days 4 meters 1999 Geoeye meters 2008 Earth-i 3*per day <1 meter Colour video 2019 Landsat 1&2 18 days 80 meters 1972 Landsat 8 15 days 30 meters 2013 Sentinel days 10 meters 2015

6 Why consider satellite imagery? Similar picture for radar (SAR) satellite imagery

7 Traditional barriers? The buying process is complex and often very manual 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.

8 Traditional barriers? Commercial license agreements Competition and technical advancements forcing change Relaxing of many areas Creative business models

9 Traditional barriers? Just an expensive picture? Cloud computing Advanced image analysis techniques Automation

10 Spottitt Service 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.

11 Satellite versus aerial photography? 10s of centimetres 4-13 spectral bands Pre-processing required 0 14 per km 2 (40cm achieve imagery) Global coverage High revisit frequency = low prob. tasking required Centimetres Typically 4 bands Analysis ready 0-35 per km 2 (12.5 cm achieve imagery) Regional/national coverage Low revisit frequency = high prob. tasking required

12 What is possible? Land Cover Analysis (Spottitt) Complex rule based algorithms tailored to renewables sector which provide 6m resolution LCA s anywhere in the world

13 What is possible? Feature match Wind turbines, storage tanks, (GeoVisual Search by Descartes Labs) AI used to find similar features all across America

14 What is possible? Feature extraction - Building recognition analysis(spottitt) Neural network trained on broad catalogue of global building types

15 What is possible? Forestry and agricultural insights (Global Surface Intelligence) Machine learning combined with high performance processing

16 What is possible? Site selection (Spottitt) Multi input analysis of exclusion zones and buffers to determine suitable sites.

17 What is possible? Monitoring and change detection - Deforestation Time-lapse based on satellite imagery

18 What is possible? Monitoring and change detection Water depth (Proteus Geo) Satellite derived bathymetry

19 To answer the question? Can Satellite Image Analysis Replace Manual Digitization? But.it has an important role to play in the generation of valuable GIS products and services.
