averageInPrecedingInterval 
averageInPrecedingInterval 
Value represents the average value over the preceding interval. 
averageInSucceedingInterval 
averageInSucceedingInterval 
Value represents the average value over the following interval. 
constantInPrecedingInterval 
constantInPrecedingInterval 
Value is constant in the preceding interval. 
constantInSucceedingInterval 
constantInSucceedingInterval 
Value is constant in the succeeding interval. 
continuous 
continuous 
A continuous time series indicates the observation result is the value of a property at the indicated instant in time. The points are essentially connected and interpolation may occur between points in order to estimate the value of the property between points. The appropriate time spacing between successive points to minimise interpolation errors is related to rate of change (wrt time) of the property. 
discontinuous 
discontinuous 
The sampling of the property occurs such that it is not possible to regard the series as continuous. The time between samples is too large to classify the measurements as continuous. 
instantaneousTotal 
instantaneousTotal 
Value represents a total attributed to a specific time instant. This is normally generated from an event based measuring device such as a tipping bucket rain gauge. 
maximumInPrecedingInterval 
maximumInPrecedingInterval 
Value represents the maximum value that was measured during the preceding time interval. 
maximumInSucceedingInterval 
maximumInSucceedingInterval 
Value represents the maximum value for the following interval. 
minimumInPrecedingInterval 
minimumInPrecedingInterval 
Value represents the minimum value that was measured during the preceding time interval. 
minimumInSucceedingInterval 
minimumInSucceedingInterval 
Value represents the minimum value for the following interval. 
precedingTotal 
precedingTotal 
Value represents the total of measurements taken within the previous time interval. 
succeedingTotal 
succeedingTotal 
Value represents the average value over the following interval.
