Profile A one-dimensional grid at fixed (x, y, t) coordinates within a four-dimensional (x, y, z, t) coordinate reference system. The grid axis is aligned with the coordinate reference system z-axis. Typically used to characterize or measure phenomena as a function of depth. SamplingCurve OGC Observations & Measurements Term retrived from OGC Observations & Measurements (e.g., see https://www.seegrid.csiro.au/wiki/AppSchemas/ObservationsAndSampling#Sampling_model) SamplingFeatureType ODM2 Working Group A vocabulary for describing the type of SamplingFeature. Many different SamplingFeature types can be represented in ODM2. SamplingFeatures of type Site and Specimen will be the most common, but many different types of varying levels of complexity can be used.
