Geographic coordinate of the location (Northing)

z

z
z

Optional elevation of the location above the global reference.

Info

The elevation defined will be used for converting a parameter supporting local and/or global datum. By convention the data stored in the DELFT-FEWS database is at the local datum. The elevation defined here is added when displaying./converting to a global datum.

The value defined for the elevation should be the gauge zero for river gauges where an exact level is important.

When using transformations and the datum needs to be converted and also a multiplier, divider and/or incrementer are defined in the time series set of the data, then the following equations are used.
When reading data from the database the calculation is:
value = (stored_value + z) * multiplier / divider + incrementer
When writing data to the database the multiplier, divider and incrementer of the time series set are not used, so the calculation is:
stored_value = value - z

Info

All time series data in DELFT-FEWS must be referenced to a location. This is the case for all data types (scalar, longitudinal, grids & polygons).

For Grids and Longitudinal profiles, additional information may be required and defined in the grids and branches configurations respectively. For scalar and polygon time series no additional information is required.
