shoreline_morphometric_space

This repository contains the code to reproduce key elements of the shoreline analysis done in Vulis et al., (2023). A single example delta is given to show necessary file structure.

The following workflow is used to reproduce the results:

• Water occurrence maps for each delta are first obtained from the Global Surface Water dataset via Google Earth Engine using GSW_monthly_history.R or GSW_occurrence.R. A shapefile containing delta outlines is in the "./analysis/globaldata/delta_outlines" folder.
• Water masks and shorelines are created using maskmaking.R. This is meant to be run in semi-interactive mode as it's necessary to choose a cardinal direction when walking on the delta. This uses the ROAM package available on GitHub which will have to be installed from source.
• Run main.R to process the shorelines into spatial-series, compute relevant metrics, and plot figures.

Paper/figures contains the publication figures output by the scripts above.
