Extremely well detailed throughout the coastal and interior area, including streets and even individual buildings. Staten Island is well developed. Insets at bottom show two offshore views of the Highland Lights, the light ship and Sandy Hook Light from different bearings. If joined the map would measure 40" x 48".
