1.1.0 (2020 annual shoreline)

In December 2021, the DEA Coastlines product was updated to version 1.1.0. This includes the following key changes to the data and web services:

Improvements and additions:

  • Added annual shoreline data for 2020. The 2020 shoreline is an interim dataset that is subject to change, and will be updated to a final version in the following 2021 DEA Coastlines update.
  • Implemented a new temporal filter that improves mapping performance across small islands and dynamic sandbars while reducing noise in areas with poor satellite coverage (#35).
  • Time series graphs are now available for non-significant rates of change points on DEA Maps (previously this was only available for retreating and growing points) (#40).
  • Australian Coastal Geomorphology Smartline and Australian Coastal Sediment Compartments datasets are now available in the "Supplementary data" folder on DEA Maps to assist in interpreting observed patterns of coastal change.
  • Added new valid_obs and valid_span fields to rates of change points that summarise the total number and temporal coverage of valid non-outlier shoreline observations. Results from valid_obs are now used to filter out unreliable rates of change points on DEA Maps by removing points with fewer than 25 valid observations (#38).
  • Climate indices (e.g. SOI) are now detrended prior to regression to remove false positives associated with trends in index values over time, and to allow climate index relationships to be modelled for coastlines with temporal erosional or progradation trends through time (#42).
  • Numerous minor improvements to inland water and estuary masking to fix areas of missing shoreline data and remove non-coastal features (#32, #33, #36).

Backwards incompatible changes:

  • Removed experimental breaks field from rates of change points (#41).
  • Removed retreat, growth fields from rates of change points (this data is already captured in rate_time, with negative values indicating retreat and positive values indicating growth).
  • Updated WMS layer group names from "dea:DEACoastLines" to "dea:DEACoastlines", and "dea:AnnualCoastlines" to "dea:AnnualShorelines"
