Overall structure 

The oceanObs API is an OGC API - Features service and follows this standard as documented here: http://docs.opengeospatial.org/is/17-069r3/17-069r3.html.

Data is returned in a FeatureCollection object that describes the returned data set. Data points are found in the features field which contains a number of Feature objects as described below.




FeatureCollection

Feature objects are wrapped in a GeoJSON FeatureCollection, which includes:

KeyNot nullData TypeDescription
typeyesStringAlways equal to "FeatureCollection"
featuresyeslist<Feature>See below for the description of the specific feature
timeStampyesStringTimestamp when the response was generated. In RFC3339 5.6 format.
numberReturnedyesNumberNumber of Feature objects returned
linksyesList of Link objects

Links to pages;

  • the link with rel="self" is a link to the page itself. 
  • the link with rel="next" is a link to the next page of results




Generic fields for every Feature

KeyNot nullTypeDescription

id

yes

String

Internal database ID

type

yes

String

Always equal to "Feature"

geometryyesObjectPosition of the station in GeoJSON format. For "Oberservation" objects it is derived from the station's location
geometry.coordinates.0yesfloatlongitude in WGS84
geometry.coordinates.1yesfloatlatitude in WGS84




Observation

This is a GeoJSON feature and the table below describes the returned data:

Key

properties.stationId

yes

String

Station ID identifying the station

properties.created

yes

String

Timestamp of create time in observation database in RFC3339 5.6 format

properties.observed

yes

String

properties.value

yes

Object

Measured value




Station

This is a GeoJSON feature and the table below describes the returned data:

KeyNot nullData TypeDescription
properties.instrumentParameteryesInstrumentParameterN/A - Currently null
properties.nameyesStringName of the station. See station list for a list of names
properties.owneryesStringOwner of the station
properties.typeyesStringStation type. See here for available types
properties.countryyesStringCountry code
properties.regionIdnoStringRegion id
properties.stationIdyesStringStation id
properties.parameterIdyesList<String>List of parameterIds as defined in Parameters schema, which the station observes
properties.statusyesStringPossible values are "Active" or "Inactive"
properties.wmoContryCodenoStringWMO country code
properties.wmoStationIdnoStringWMO station id
properties.createdyesStringCreation time in database (in RFC3339 5.6 format, e.g. "2020-07-10T07:59:38Z")
properties.operationTonoStringLast date the station is operational in RFC3339 5.6 format. If the station is currently operational this field is null
properties.operationFromyesStringFirst date the station is operational in RFC3339 5.6 format
properties.updatednoStringLast station update in RFC3339 5.6 format. Update may be a new location, changes to instrument parameters etc
properties.validTonoStringLast date the station sends valid data in RFC3339 5.6 format. For now this is the same as operationTo, but may change in future versions
properties.validFromyesStringFirst date the station sends valid data in RFC3339 5.6 format. For now this is the same as operationFrom, but may change in future versions
