Vessel:	The first entry is always [Reference Vessel] This means that the first defined object will be used (with Object Id 1). In Database Setup you will see a 'square' icon in front of the vessel name: The rest of the list will show all available objects, existing in the current selected Qinsy database (see General Layout Information about loading a Qinsy database).

Height

Value [in survey units] of the Height Aided Observation, which is calculated by the Height Aiding driver. Driver is always present in the Windows task-bar.

The Height value is by default on Chart Datum (also known as Vertical Datum), but Survey Datum or WGS84 may be selected.

Note that this value is the same as the height of the reference node for the selected vessel.

double

Datum:

Survey Datum
Height value will be on the selected survey datum ellipsoid, e.g. ED50.
Survey Datum (or Horizontal Datum) is set in the Geodetic Configuration as Project CRS.
WGS84
Height value on the WGS'84 datum.
Notice that WGS84 (or ITRF2008) must be one of the two selected CRS's in the Geodetic Configuration.
Chart Datum (default)
Height value on the selected vertical datum e.g NAP, De Min Geoid.
Chart Datum (or Vertical Datum) is set in the Geodetic configuration as Vertical CRS.

Height Status

Two possible values: one or zero.

0: The height aided observation is not used in any of the computations: The height status of the triggering system (located on the selected vessel) is set to Accurate in all available computations.

1: The height aided observation is used in at least one of the computations. I.e. that the height status of the triggering system (located on the selected vessel) is set to Unreliable in one of the computations.

int

Height Sd

1 Sigma (68%) A-Priori Standard deviation of the Height Aiding observation

double

Heave

Heave component of the Height Aided Observation.

double

Heave Status

Two possible values:
1: Heavecomponent is part of the height aided observation
0: No heave component, or no height aided observation at all

int

Squat

Squat component of the Height Aided Observation.

double

Squat Status

Two possible values:
1: Squat component is part of the height aided observation
0: No squat component, or no height aided observation at all

int

Draft

Draft component of the Height Aided Observation.

double

Draft Status

Two possible values:
1: Draft component is part of the height aided observation
0: No draft component, or no height aided observation at all

int

Tide

Tide component of the Height Aided Observation.

Notice that this item is the same as item Tide under Tide Results

double

Tide Status

Two possible values:
1: Tide component is part of the height aided observation
0: No tide component, or no height aided observation at all

Notice that this item is the same as item Tide Status under Tide Results

int

MWL Model

Mean Water Level Model component (often known as Mean Sea Level) of the Height Aided Observation.

double

MWL Model Status

Two possible values:
1: MWL (Mean Water Level) Model component is part of the height aided observation
0: No MWL Model defined (in Db Setup), or no height aided observation at all

int

Depth

ROV Depth component of the Height Aided Observation.

double

Depth Status

Two possible values:
1: ROV Depth component is part of the height aided observation
0: No depth component, or no height aided observation at all

int

Actual Water Level

The actual water level above Survey Datum

For the object's reference node the "Height above Actual Water level" value is used minus the "Height above Survey/WGS84/Chart Datum" value.

double

Datum:

Survey Datum
Height value will be on the selected survey datum ellipsoid, e.g ED50.
Survey datum (or Horizontal Datum) is set in the Geodetic Configuration as Project CRS.
WGS84
Height value on the WGS'84 datum.
Notice that WGS84 (or ITRF2008) must be one of the two selected CRS's in the Geodetic Configuration.
Chart Datum (default)
Height value on the selected vertical datum e.g NAP, De Min Geoide.
Chart Datum (or Vertical Datum) is set in the Geodetic configuration as Vertical CRS.

Mean Actual Water Level

The Actual Water Level (see above) minus the heave of the object, so i.e. the actual water level without the swell influence.

double

Datum:

Survey Datum
Height value will be on the selected survey datum ellipsoid, e.g ED50.
Survey datum (or Horizontal Datum) is set in the Geodetic Configuration as Project CRS.
WGS84
Height value on the WGS'84 datum.
Notice that WGS84 (or ITRF2008) must be one of the two selected CRS's in the Geodetic Configuration.
Chart Datum (default)
Height value on the selected vertical datum e.g NAP, De Min Geoide.
Chart Datum (or Vertical Datum) is set in the Geodetic configuration as Vertical CRS.

Mean Water Level

The Actual Water Level (see above) minus the heave of the object (swell) and minus the tide.

double

Datum:

Survey Datum
Height value will be on the selected survey datum ellipsoid, e.g ED50.

MWL Geoid Height

The current geoid height above survey datum.
This is the calculated height value for the vessel location from the Mean Water Level model. This model is selected in the database setup, Edit menu, Advanced settings, Mean Water Level Model:

double

MWL Level Height

The current level height above geoid datum.

This is the calculated height value for the vessel location from the Mean Water Level model.
This model is selected in the database setup, Edit menu, Advanced settings, Mean Water Level Model, using the second drop-down list selection. Normally you select here your River Lines model.

double

MWL Height Offset

The height offset above level datum.
This is a fixed offset value as entered in the database setup, Edit menu, Advanced settings, Mean Water Level Model.

Note that this item is actually the same as item "MWL Model Height Offset" in group SETUP DATA, category Geodetics.
