ERDDAP (Environmental Research Division Data Access Portal) data is sourced from the ERDDAP server using the rerddap R library.
As data on the ERDDAP server is updated regularly this provides the
opportunity for interactive figures using ERDDAP data to be updated
regularly as well. The first step in this process is to update the
relevant tables, which for the Channel Islands Marine Sanctuary (CINMS)
are located at: https://github.com/marinebon/cinms/tree/master/data/oceano.
These tables, saved in csv format, are updated monthly via GitHub
Actions using the update_oceano.yml
workflow. This workflow in turn calls the R script update_oceano-data.R,
which uses the calculate_statistics() and
calculate_SST_anomaly functions from the
onmsR package to update the relevant csv files.
Once the data tables have been updated, the next step is to update
the figures that draw upon those tables. This is done by rerendering the
modal windows (which are R Markdown files) that contain those figures.
This also occurs on a monthly basis via GitHub Actions using the update_oceano.yml
workflow. The workflow calls the R script render_oceano-modals.R,
which calls the onmsR function
render_all_rmd() to update the relevant modal windows.
