Software download and FAQ

As part of the SeaDataNet CDI data discovery and access services, data sets are accessible to users via download services. Data sets are then delivered in common data transport formats, which interact with other SeaDataNet standards (Vocabularies, Quality Flag Scale) and SeaDataNet analysis & presentation tools (ODV, DIVA).

Depending on their local data management configuration, data centres might be required to pre-process their in-house data files from their own formats to the SeaDataNet data formats. To support data centres for this conversion, SeaDataNet is providing NEMO software as a useful tool (written in java). NEMO enables conversion from any type of ASCII format to the SeaDataNet ODV and Medatlas ASCII formats as well as the SeaDataNet NetCDF (CF) format (for timeseries, profiles and trajectories observations) . NEMO makes use of the Common Vocabularies and EDMO directory. The latter are each time synchronised by online connections to the respective Web Services on user demand.
