The elevation model is generated from DEA Landsat and Sentinel-2 surface reflectance data from each 3-year composite period, utilising a pixel-based approach based on Ensemble Tidal Modelling. For every pixel, the time series of surface reflectance data is converted to the Normalised Difference Water Index (NDWI) and each observation tagged with the tidal height modelled at the time of acquisition by the satellite. A rolling median is applied from low to high tide to reduce noise (such as white water, sunglint, and non-tidal water level variability), then analysed to identify the tide height at which the pixel transitions from dry to wet. This tide height represents the elevation of the pixel. -`name` elevation  +Layer attributes: -`datatype` float32  - -`units` metres above MSL  +:::{list-table} -`nodata` NaN  +* - **Name** + - `elevation` +* - **Data type** + - `float32` +* - **Units** + - `metres above MSL` +* - **'No data' value** + - `NaN` +::: #### DEA Intertidal Elevation Uncertainty @@ -270,7 +276,7 @@ This shift to a more dynamic product suite is achieved through a pixel-based alg * Tidal metrics calculated by comparing satellite-observed tides against high frequency modelled tides. -## Code repositories +## Code repositories [DEA Intertidal Github](https://github.com/GeoscienceAustralia/dea-intertidal) - codebase for DEA Intertidal product generation workflows @@ -282,7 +288,7 @@ This shift to a more dynamic product suite is achieved through a pixel-based alg Beaman, R. 2023.
