Perú TopoJSON 2024

This repo contains scripts and input files to generate a TopoJSON file covering the following geography layers. (You can preview and download individual geographies with this tool).

Running the scripts

First, you will need to install the NodeJS dependencies. Assuming you have NodeJS installed, simply run:

npm install

Next, you will need to run the scripts. This can be done with a single command:

npm run make-topo

You can preview the output locally by running the included Svelte app:

npm run dev

Editing/updating the config

To update geographies for year-on-year mergers of local authorities or terminations of counties, you should only need to edit the /input/changes.csv file.

If you want to make more complex changes (eg. mergers or terminations of other geographies, or additons of new geography types), you will likely also need to edit /input/ltla14_lookup.csv, /scripts/make-lookup.js, and possibly other files.

Visualization

This work follows these steps:

• Division into svelte components.
• Refactoring svelte components to match with Perú area code.
• Changing raster style to carto.
• Changing scripts to merge cartography of other countries.
