A 3D rendered map of Zavodovski Island, the northern-most island of the South Sandwich Island chain. This model was created using a hand-drawn topo map, photographs and satellite images as references. A digital elevation model (DEM) was created by plotting the elevation points, then given natural textures and features using the 3D modeling program Terragen. From the book The Pursuit of Endurance – On The Shoulders of Shackleton.
