Publishing

Clone the repository

Prepare the municipal boundaries

1. Download and extract the data into a specific directory. Peek into gml_to_geojson.sh for the path.
2. Run ./gml_to_geojson.sh to transform the municipal boundaries from GML to GeoJSON and into the right spatial reference system.
3. Copy the transformed file into leaflet/app/data/.

Prepare the member list

1. Download the data into a specific file. Peek into member_csv_to_json.sh for the filename.
2. Run ./member_csv_to_json.sh to transform the CSV file into a JSON file.
3. Copy the transformed file into leaflet/app/data/.

Build and publish the map

1. Run the following:

cd leaflet
npm install
bower install
node_modules/.bin/gulp

2. Publish the contents of dist/. The directory contains static files only.

Note

• Only members with the domicile set to a name of a Finnish municipality, in Finnish or in Swedish, are counted.
  • This excludes members who live abroad.
  • This excludes members who made a typo.
  • This excludes members who put more specific location information into the field.
  • This excludes members who did not report their domicile at all.
• The total count of all OKFFI members, visible on clicking any municipality, includes all members regardless of domicile.
• Humans and legal entities, e.g. other NGOs, are not separated in the calculations.
• The coloring algorithm is quite ad-hoc. It is meant to visually separate where there are many, few or no members. The colors are not meant for reading absolute numbers or proportions.

Todo

• Here are the members as a CSV.
  • Use papaparse to parse the CSV in the browser.
    • "papaparse": "~4.1.0", into bower.json
