This page outlines the key aspects of the data service suite (following a decision to cease development based on DX).

Enterprise Viewpoint

Need to be able to extract a cruise-section-equivalent from a model dataset (e.g. ERA40) at BADC and difference against a BODC actual cruise.

Information View Point

  • CSML Schema description of a GridSeriesFeature
    • GridSeriesInterface exposes an extractProfile, but does it expose extractProfileSeries?
  • CSML Schema description of a ProfileSeries
  • CSML Instances at both locations
  • Binary Files at both locations
