As you learned previously, Natural Earth is a website created to provide vector and raster data to meet the needs of cartographers using a variety of software applications. The data on this website is free to use without restrictions. Open the Chrome browser and navigate to the Natural Earth website. Click the Downloads link. Under Small scale data, click the Cultural link (Figure 2.01).
If for some reason the website has changed or is not working properly, you can download a backup copy of the data using the following link: https://bit.ly/uncertainty-prj-datum
Under Admin 0–Countries, right-click Download countries (Figure 2.02). Select, Save Link As, then navigate to your original folder and save.
Scroll down until you see Populated Places (Figure 2.03). Right-click the button that says Download populated places, select Save Link as, then navigate to your original folder and save.
When you are ready, hit the back button and return to the main downloads page. Click Physical under Small scale data. On the Physical Vectors page, scroll down until you see Graticules (Figure 2.04). Right-click on the button that says Download 10. Select, Save Link As, then navigate to your original folder and save.
Previously, you learned how to decompress a file using 7zip. In Microsoft Windows, navigate to your original folder. You should see the three zip files, one for countries, one for populated places, and one for graticules (Figure 2.05). For each zip file, right-click, select 7zip, then Extract Here.
Be sure to delete the zip files when you are done decompressing them (Figure 2.06). You won’t need them anymore. Eliminating them saves space and helps to avoid confusion later.
