NQUERY

IDARS
NQuery is a Java-based, network-enabled data-based query tool that assists the scientist who has selected in-situ datasets within a desired time-space bounding box, and wishes to refine that data selection based on characteristics of the data itself. Examples of such a query might be a request for average temperatures exceeding a specific value, or values along a bathymetry contour. Such a capability is particularly important when the data collections or datasets are very large and located on remote, network accessible data servers. NQuery is a software application for ingesting oceanographic profile data and building a database from values calculated form the observed values. Currently, NQuery is limited to oceanographic profile data.
