About CetaHAV
CetaHAV is a pilot marine digital twin for Swedish waters. It integrates publicly available data streams onto a single map so that shipping companies, fisheries, planners, environmental agencies and researchers can answer real questions with real data.
Core data streams
- Meteorological data
- Wind, temperature, pressure (e.g. SMHI)
- Oceanographic data
- Currents, salinity, sea level (e.g. Copernicus Marine)
- Hydrographic data
- Bathymetry and nautical charts (e.g. SMA, EMODnet)
- AIS positional data
- Live & historical vessel traffic
- Environmental monitoring
- Water quality, nutrients, biota (e.g. HELCOM, SMHI)
- Earth observation
- Satellite imagery for ice, chlorophyll, SST
