# 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_set_extent.R` - This script sets the data directory and loads the extent from `extent.csv`.
|
|
- `02_download_data.R` - This will take the longest. It downloads the data to a `data/` directory in the repo. The whole of Wisconsin downloads ~12GB of data. This script can be skipped after you have already downloaded the data, and the extent is within what you downloaded.
|
|
- `03_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.
|
|
- `04_make_figures.R` - This generates figures in the `figures/` directory in the repo.
|
|
- `05_make_cnc_figures.R` - This generates svg files in the `figures/` directory for use in laser cutters and other cnc machines
|
|
|
|

|
|
- `R`
