Waterline contour extraction

Triangulated Irregular Network interpolation

Processing steps

Extract waterline contours along boundary of each ITEM tidal interval (i.e. each ten percent of the observed tidal range)

Assign contours with median and standard deviation tide heights of Landsat observations for each tidal interval

Generate continuous elevation data from median tide heights per contour using Triangulated Irregular Network interpolation

Clean and filter DEMs to remove noise, modelling artefacts and invalid elevation estimates
