Determination of the HAT mark depends on the availability of high precision topography (in the format of LiDAR DEM data).
At the present this topographyincludes the coast from Queensland - New South Wales border to Port Douglas, as well as Badu, Coconut, Darnley, Dauan, Entrance, Friday, Hammond, Horn, Lizard, Mabuiag, Maer, Masiq, Packe, Palfrey, Prince of Wales, Round, South, Stephens, Thursday, Turtle, Turtle Head, Wednesday, Yam Islands and Pai Bai Tud and Sue Islets as well as in the vicinity Aloa, Cooktown, Injinoo, Karumba, Napranum, New Mapoon, Normanton, Seisia, Umagico, Weipa, Wujal Wujal, Cape Bedford and Forsberg Point.

An elevation error in the HAT DEM and in the topographic DEM, the estimate of the total error is the sum of the errors from the individual sources is a 0.1m constant plus a variable 0.15m that may be positive or negative).
As a worst case example, if the ground slope is 1:1000 then the location error estimate ranges between 50m and 250m. The error diminishes as the slope of the ground increases.

The data is to a standard determined as fit for the purpose for which it was collected.
true
This dataset is GDA2020 compatible. The source data, and therefore the captured features, are georeferenced as GDA94 (horizontal only). The horizontal accuracy of the geo-referencing and/or data collection method for this example is greater than the datum offset between GDA94 and GDA2020 (1.8 meters). The resulting dataset has been nominated as a low-accuracy GDA2020 dataset. As this data has not been directly captured in GDA2020, nor transformed to GDA2020, the resulting data is 'GDA2020 Compatible' not 'GDA2020 Compliant'.
A surface model representing the HAT – AHD separation was produced from maximum recorded tide levels at tide gauges along the QLD coast. The HAT line is generated from the intersection of the HAT-AHD separation surface model with a ground surface model provided by 1 or 5 metre LiDAR DEM data (captured 2006 – 2011) with vertical accuracy approximately 0.15m at one standard deviation.
This methodology is based on a somewhat generalised HAT-AHD separation model and does not take into consideration localised hydraulic dynamics within the intertidal zone along the QLD coast.
Feature Types:
Highest Astronomical Tide - A line displaying the highest water level that can be predicted to occur under any combination of astronomical conditions.
Attributes:
FEATURETYPE - Unique feature type that identifies the topographic feature e.g. Highest Astronomical Tide FEATURERELIABILITY - Reliability date of the source information FEATURESOURCE - The data that the spatial location of the feature was obtained from. ATTRIBUTERELIABILTY - Reliability date of the document or authority that the name of the feature was acquired from. ATTRIBUTESOURCE - The source (imagery, map or data) used for attributing (naming) of the feature. If no name is present then the attribute source will be the imagery, map or data used to define the feature type PLANIMETRICACCURACY - The standard deviation of the horizontal positional accuracy. DESCRIPTION - Information describing the line (Dominant, Depression, Extent, Isolation). Dominant is the general HAT line that can be merged to form a continuous line, Depression is a depression area between the Dominant line and the sea, Isolation are areas of higher elevation between the Dominant line and the sea, Extent are areas beyond the Dominant line.
