A detailed description of each layer of data can be found here.
The maps can be viewed in a browser window with MapMaker or with Google Earth by clicking on the “Download With Google Earth” button below. Unfortunately, it is not possible to display the legends in Google Earth, so you will still need to reference MapMaker to determine what the colors on the map represent, although in most cases, it is obvious without having to look up the legend.
