pretty_rivers

Downloads USGS data for a given location and makes a pretty map of the rivers. The width of the rivers is proportional to the area of land that the section of river drains.

To run :

1. Clone the repository
2. Edit the extent of the map you want to produce in extent.csv. Include lat/long coordinates of two opposite corners (i.e. top-left and bottom-right).
3. Run the scripts:
   • 01_download_data.R - This will take the longest. The whole of Wisconsin downloads ~12GB of data. It downloads the data to a data/ directory in the repo
   • 02_process_data.R - This loads and processes the data. After the initial run downloading the data for a given extent, you can start with this script.
   • 03_make_figures.R - This generates figures in a figures/ directory in the repo.

required packages/libraries installed:

• R
• nhdplusTools
• sf
