Attribute | Scope | Type
accuracy | Public | Percentage
definition=The extent to which the value is expected to be free from error, measured as a percentage of the data value. 100% means fully accurate. order=0
computationMethod | Public | ComputationMethodEnum
definition=Method of computation which is used to compute the measured value at the measurement site. order=1
defaultMeasurementHeight | Public | MetresAsFloat
definition=Default height, above (positive value) or below (negative value) ground level, at which measurements are made. For example in wind measurement this could be the height of an anemometer. order=2
measurementSide | Public | DirectionEnum
definition=Side of the road on which measurements are acquired, corresponding to the direction of the road. order=3
period | Public | Seconds
definition=The time elapsed between the beginning and the end of the sampling or measurement period. This item may differ from the unit attribute; e.g. an hourly flow can be estimated from a 5-minute measurement period. order=4
smoothingFactor | Public | Float
definition=Coefficient required when a moving average is computed to give specific weights to the former average and the new data. A typical formula is, F being the smoothing factor: New average = (old average) F + (new data) (1 - F). order=5
specificMeasurementValueType | Public | MeasuredOrDerivedDataTypeEnum
definition=The type of this specific measurement at the measurement site. order=6
