Downloading Data from Natural Earth
Natural Earth is a website created to provide free vector and raster data to meet the needs of cartographers using a variety of software applications. Tom Patterson and Nathaniel Vaughn Kelso (HSU alumni) are the primary authors. The data on this website is free to use without restrictions.
Open the Chrome browser and navigate to the Natural Earth website at http://www.naturalearthdata.com/. Click the Downloads link. Under Large-scale data, click the Cultural link.
If you do not have the Chrome browser, you can download it here.
Under Admin 1 – States, Provinces, right-click Download states and provinces. Select, Save Link As, then navigate to your original folder and save.
In a previous activity, you learned how to decompress a file using 7zip. In Microsoft Windows, navigate to your Original folder. You should see the zip file for the states and provinces. Right-click, select 7zip, then Extract Here. Be sure to delete the zip file when you are done decompressing it. You won’t need it anymore. Eliminating the zip file saves space and helps to avoid confusion later.
