Guided Instruction

This file has you take an active role in learning by getting some coding practice changing the CRS of a plot. It also reviews one method for reading in zipped files using temporary files. Using rio package to read in the zip files may also work. (Rendering this .qmd file may make it easier to read)

We have been asked by the state of Idaho to visualize their water systems in the state: wells, dams, and a couple of key rivers.

Though not necessary for this assignment, you may wish to challenge yourself by visiting the Idaho Department of Water Resources website and trying to find the wells dataset and the dams dataset on their site. You can also find files to use in the “Task” portion of the assignment.

Below are the links to the data zip/files:

  1. Read in all four of the necessary SHP file datasets.
  2. Filter the data so that
    • Only well locations with a production of more than 5000 gallons are included
    • Only large dams (surface area larger than 50 acres) are included
    • The Snake River and Henrys Fork rivers are the only bodies of water that should be included.
  3. Change the projection so that Idaho is not tilted when plotted.
  4. Create a map of Idaho showing these key water system features and save it as a .png file.
  5. Render your .qmd file. Push your .png,, .qmd, .md, and .html to your GitHub repository.
