Lesson Data

This section provides links to download the Lesson 4 data and reference information about each dataset (metadata). Briefly review the information below so you have a general idea of the data we will use in this lesson.

Lesson 4 Data Download:

Note: You should not complete this activity until you have read through all of the pages in Lesson 4. See the Lesson 4 Checklist for further information.

Create a new folder in your GEOG487 folder called "L4." Download a zip file of the Lesson 4 Data and save it in your "L4" folder. Extract the zip file and view the contents. Information about all datasets used in the lesson is provided below.


In Lesson 4, we will use many of the same datasets from Lesson 3, including the custom data sets we created in Part II of the Step-by-Step Activity. I have provided clean copies of these datasets in the zip file above. Please use these during Lesson 4, just in case you made an error during Lesson 3. You may want to compare the data you created in Lesson 3 to the provided datasets and see if there are any differences.
