MPA Europe maps platform

This is the repository for the maps platform being developed by OBIS to hold the SDM (Species Distribution Models) maps produced as part of the MPA Europe project.

The platform uses Quarto and Shiny, and is still under development. You can access the platform here: (https://shiny.obis.org/distmaps/)

Repository structure

The main files are:

• index.qmd: Quarto file used to generate the webpage and the frontend part of the app (generate index.html).
• _quarto.yml: Quarto configuration file.
• www/addons.js: Javascript additional functions.
• www/styles.css: CSS stylesheet for personalization of the interface.

Main folders:

• quarto_components: Page sections.
• components: Shiny server-side components.
• scripts: R functions/scripts needed within components.

Components explanation:

• serverstart.R: Information loaded on server start
• tabactions.R: Tab control/actions
• tabcontexts.R: Tab contextual information
• updateoptions.R: Update selectize options
• selectinfo.R: Main information from input
• contextualinfo.R: Add/update contextual information
• dataloaders.R: Load accessory data
• renders.R: Contextual information renders
• maprenders.R: Map render and placeholder
• mapreactive.R: Main reactive for map change
• extrainfo.R: Extra information section
• extrainfomaps.R: Extra information popup - maps
• downloads.R: Manage download requests

The zip folder app_bundle.zip contains files produced by pre-render.R and is provided for a faster deployment on server. The script build.R, which should be called on the server when the app is deployed, will unzip this file on the data folder.
