This tutorial covers how to use the Google Maps public site to create an interactive, robust map on your website complete with pins, boundaries, etc. It's important to understand when creating a map while you are logged into your Google account, traffic to the map counts towards your monthly quota. In most cases, maps on school websites will not see enough traffic to run over your quota. The maps data is also saved to your google drive. So, you can come back and edit the map any time and the latest map will render on your site without having to update the snippet.
