Designed to accompany and explain the first comprehensive survey of the entire Austrian Empire (including the new kingdom of Galicia), this legend defines the scale of the maps plus the meaning of the colors and more than 30 feature types on the maps. Particular attention is paid to fortifications, resources, and communication pathways. This map image is from Wikimedia Commons. A full overlay map of the First Military Survey of Galicia is available on the Mapire website.
