One oddity of Google Earth is that while you can measure distances, and also draw paths, there’s no direct way to determine the length of a path you’ve drawn. I’ve previously covered several applications that will take a KML path file and determine its total length; all of the require that the path file be a KML, not KMZ file.

Click the “Attach file” link to select the file on your computer:
Then click “Find Path Length” to, ummm, you know:
And you’ll also get back the input screen so that you can select another file. As a bonus, the website cycles through scenic backgrounds, and you have the lovely angler fish logos to look at; you can even order a T-shirt with the logo.
