| 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.
