Once you have downloaded the historic sites and historic districts data from COHGIS Open Data Portal and the major rivers data from H-GAC, you will be able to find the data files in your Downloads folder. You will see that all the files are zipped, meaning they contain compressed files of data within them (you can tell a file is zipped when the file type column reads “Compressed (zipped) Folder”). You will need to unzip the folders to be able to see the data inside them. 

1. On the Desktop, click the File Explorer icon located on the Windows Taskbar on the bottom left corner of the screen. 
2. Navigate to the Downloads folder.
3. Ensure that you see the following zipped folders in your Downloads folder.
