Project Tovel part 3: georeferencing historical maps

In many archaeological GIS a very important step is the study of historical maps. During the Project Tovel this stage has been a primary target, being strictly related to the 3D reconstruction of the underwater surface of the lake. In fact one of the best source for the bathymetry of Tovel is the plan drawn, between 1937 and 1938, by Edgardo Baldi (director of the "Istituto italiano di idrobiologia Dott.
