This zoomable map was made possible using Zoomify.
The map below is based on the Galileo/Voyager basemap created by the USGS's Astrogeology Group in Flagstaff, Arizona. Labels have been added for named surface features. The controls below the map allow you to zoom in all the way to the full resolution of the map, pan around the map, and make the map full-screen. You can also use your mouse on the map itself to pan across the image. I am still looking into the possibility of using different layers so you can turn labels on and off, and have volcanic hotspots indicated on the map.
