5. Why focus on global data services?
Towards services ‘Global’ sets an ambition Market for global information

6. Global Data Services
Incredible content
Develop incredible content such that our members will
not be shy to share the content
Consulting
Allow members to gain access to our consulting
expertise
Paid subscribers
This is optional, not sure yet if this applicable for all
data/services. Ideally everything should be free for
everyone but we need to cover at least our OPEX
Free services
Capture potential members with free-mium model
Data as a Service
Great data
Give access to incredible data such that our clients will
and can re-use the data for their own benefit
Information as a Service
Valuable information
Give access to valuable information such that our
clients will and can re-use the info for their own benefit
Platform as a Service
Collaboration and impact
Allow members and clients to gain access to our data,
information and expertise to collaborate with us and
the community.

As a windfarm operator, I want to assess metocean conditions at my
windfarm, to assess workability conditions.

As a coastal manager, I want to assess the state of my coast every
year & after storms, to decide for mitigating measures.

14. Global Tide and Surge Model v3.0
• 2D barotropic model
• Unstructured global grid
(25 km ocean - 2.5km coastal/1.25km EU)
• Bathymetry:
• EMODnet (250m) for EU
• Bedmap2 below lat 60S
• GEBCO 2014 bathymetry(~1km)
• TGF driven, no assimilation
Runtimes in 8 cores ~3.6hour/week

15. GLOSSIS: real-time water level and storm-surge forecasts
at world-wide scale
• Real-time, medium-term forecasts
• Historical timeseries
• anywhere
• Ingredients:
• Deltares expertise: hydrodynamics, storm surge,
wave, bathemetry
• Computational engine: Delft3D FM based GTSM model
• Forecasting platform: Delft-FEWS
• Storage: Deltares OpenArchive

17. GLOFFIS: real-time hydrological forecasts at world-wide scale
• Medium-term and seasonal fluvial flow
forecasts
• Historical timeseries
• anywhere
• Ingredients:
• Deltares expertise: hydrology, WRM, forecasting
• Computational engine: Delft3D FM based
models:
• D-Hydrology (wflow)
• D-Flow FM (1D)
• Forecasting platform: Delft-FEWS
• Storage: Deltares OpenArchive

19. Where are we now with the Global Data Services
• Still under development (early beta stage at present)
• Available on the Deltares network (now)
• Available for external beta-testers Q1 2020 (sign up)
• Official release end of Q1 2020

20. Where are we now and next steps
Develop a platform that has:
• Easy access to (global) data
• Enables quick setup of model & tools
• Includes a Model Analysis Framework
• To support Water Resources Management & Planning
• Upcoming data sets:
• Water levels & currents for RCP4.5 and RCP8.5
• Extreme precipitation due to global warming
• Urbanization and Human Settlements
• …

21. Your feedback is appreciated
• General look and feel
• Which additional features would be useful
• Are the available data sources useful
• What should be changed to make it (more) useful
• What kind of opportunities do you see?

22. Thank you!
