v0.2.0
942e40a

0.2.0 (May 5, 2020)

Features

  • Add 'uncertainty' column to contour data for pixels with either less than 5 observations or > 0.25 MNDWI standard deviation in more than 50% of years
  • Add new DEACoastLines_utilities.ipynb notebook containing additional functions for using DEA CoastLines data
  • Add rates_hist utility function for plotting DEACoastLine statistics data as a histogram based on an interactive selection
  • Add ability to modify waterbody mask by providing a vector files of features to add or remove from the mask
  • Add new deacoastlines_summary.py script for generating continental summary of point statistics based on average values within a buffer of X km of a subset of points. This allows hotspots to be visualised at full zoom out

Bug fixes

  • In deacoastlines_generation.py: Fixed missing grid cell areas by buffering both the input grid cell extent and tide modelling extent by 0.05 degrees (i.e. a total of 0.10 degrees). This ensures that enough tidal modelling points are available for interpolation, and improves tidal modelling consistency between neighbouring grid cells
  • In deacoastlines_generation.py: Break script early if grid cell correspondes to 1 or less tidal modelling points, as this makes tidal interpolation impossible
  • In deacoastlines_generation.py: Increase dask_chunks to {'time': 1, 'x': 2000, 'y': 2000} for improved data load performance
  • In deacoastlines_statistics.py: Fixed missing shorelines caused by the waterbody mask by limiting mask to specific waterbody features ('Aquaculture Area', 'Estuary', 'Watercourse Area', 'Salt Evaporator', 'Settling Pond' and perennial 'Lakes')
  • In deacoastlines_statistics.py: Fix CRS of exported GeoJSON contours and statistics files by converting to EPSG:4326
  • In deacoastlines_statistics.py: Remove previous zeroing of yearly distance values to 1988. Yearly distances are now relative to the 2018 baseline (e.g. 0 for the 2018 contour), which should be simpler easier to interpret
  • In deacoastlines_statistics.py: Increase min_vertices for contour extraction to 30 to reduce noise
  • In deacoastlines_statistics.py: Move vector directory creation until after data load, so no directory is created if rasters do not exist

v0.1.0 (April 1, 2020)

Features

  • First continental run of DEACoastLines
  • Outlier detection now uses a more robust Median Absolute Deviation method

Bug fixes

  • In deacoastlines_statistics.py: Remove mask applied to contour generation due to excessive missing data
