What data/products do you currently use ? |
Need currently being partly fulfilled. Forecast: ocean current data, consultancy, model data such as Hycom, ECMWF, NCEP |
||||
5 |
When do you use this kind of dataset? |
These data are needed during the Survey preparation (Hindcast). They are helpful for finding a weather window to conduct operations and avoid downtime. It hen helps to reduce the survey duration by planning and optimizing operations. (Forecast) |

What are your actual limitations and do you have a work around? |
Ocean current forecast:
Ocean models:

Needs and expectations on EO data |
Satellite images: they are just inputs to other products or services. The company needs the global picture as a result of a combination of in-situ measurements, EO and combination of EO, models, and this is what is expected from the service companies. |

14 |
Temporal resolution |
Tidal: hourly Current: daily if nothing else is available Monthly mean |
||||
15 |
Spatial resolution |
1m, 100m, 1 km / 1:50000, 1:25000 ... Model : ¼° SAR image : 1/150000 |
||||
16 |
Data quality |
Higher for lakes as info for ground truthing/Very important during operations |
||||
17 |
Data Coverage and extent |
Over survey area, typically 100km x 100km/Along track, programmable |
||||
18 |
Example formats |
e.g. GeoTIFF, Report, GIS formatsn NetCDF etc... raw data and geotiffs |
||||
