If we store our Wi-Fi SSIDs and GPS location in external storage such as a microSD card, we map the Wi-Fi hotspot into Google Maps. You can view Google Maps at https://www.google.com/maps/d/. After logging into Google Maps, you can see the web form in Figure 7.9:

To create a new private map, you can click on the CREATE A NEW MAP button; you will then see something similar to Figure 7.10.
Now you can upload a CVS file that consists of a Wi-Fi SSID and its locations. You should see your Wi-Fi SSID names on the map:

You can experiment with what we have learned here in your own time. I recommend looking at an example of the Wardriving project at https://wigle.net/.
