National Parks Map

Program screenshot

This web app displays the 63 U.S. national parks on a map. Larger circles indicate that the park had more visitors in 2021. The base map is from Mapbox and the park data is from Wikipedia.

How to Run the App

Download this repository and get an API key from Mapbox. Create a file, src/api-key.json, and add the following to its content with your own API key:
{"key":"API_KEY_GOES_HERE"}

Then run in terminal:
npm install
npm start

How to Run the Scraper

To avoid straining Wikipedia servers, this scraper does not make any HTTP requests. Instead, you must download the HTML file of this Wikipedia article which contains a list of national parks. Then, rename it to wikipedia-article.html and move it to the scrape-data folder.

scrape-data/extract-park-data.py is a script which reads the content of scrape-data/wikipedia-article.html and extracts national park data from it to generate src/national-parks.json, which is read directly by the app. Since src/national-parks.json has already been generated, you do not need to run the scraper to run the mapping app. The article was downloaded on Decmber 10, 2022, to generate the existing data.

Install Python dependencies:
pip install -r scrape-data/requirements.txt

Run the Python script to generate src/national-parks.json:
python scrape-data/extract-park-data.py
