ESEAS data exchange format
|
A standard ESEAS data format has been accepted to enable exchange
of oceanographic data where acquisition method can
be interpreted as the time series in a permanent geographic location.
Originally, the ESEAS format has been agreed for tide gauge data exchange
by the IOC’s Group of Experts .
In the framework of the SESAME project, the ESEAS format has been adopted and expanded.
In order to formalize the format, references to standard vocabularies for
metadata are added to the following format description.
