Unfortunately, many of us unwitting share that information anyway if you happen to have smartphone or fancier camera.  There are ways to remove this, including some apps.  I think it is very important to know not just for saving your favorite outdoor locations, but even posting photos taken around your house.

"GPS coordinates are stored as “metadata” embedded in the photo files themselves. All you have to do is view the file’s properties and look for it...

In Windows, all you have to do is right-click a picture file, select “Properties,” and then click the “Details” tab in the properties window. Look for the Latitude and Longitude coordinates under GPS.

In macOS, right-click the image file (or Control+click it), and select “Get Info.” You’ll see the Latitude and Longitude coordinates under the “More Info” section"
