# 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
- 02_process_data.R
- 03_make_figures.R). 
Downloading the data and loading the data will take the longest. The whole of Wisconsin downloads ~12GB of data
