Object datum output (Water Overlay)
|OBJECT_DATUM_OUTPUT||m + datum||An array of values, two per timeframe. Each value indicates the water level at one sides of the hydraulic structures, entry or exit.||None|
All hydraulic structures have an OBJECT_DATUM_OUTPUT attribute.
- This attribute does not need to be created when configuring the project. This attribute is created automatically by the Water Overlay when a calculation is performed. When the calculation is complete, the attribute is updated automatically.
- Each Water Overlay will create this attribute with the ID of an Overlay appended to it, to prevent the results of multiple Water Overlays storing their results in the same attribute by default.
- This attribute is also visible when zoomed in on a hydraulic structure. The water levels on either side of the structure can be seen at each timeframe when a Water Overlay is selected.
