Southern Sierra Aerochart Three Dimensional 3D Raised Relief Map

Southern Sierra Aerochart Three Dimensional 3D Raised Relief Map Horizontal Scale: 1:500,000 (1" = 7.9 miles) Size: 30" x 20" This 3D FAA Sectional aeronautical raised relief wall chart covers the high Southern Sierra Nevada Mountains, from Yosemite and Mammoth to Bakersfield and Mojave. The precisely molded 3D shape allows pilots to see and feel the terrain shape and clearly understand how it relates to the airspace and flight. Pilots will value referencing this chart for flight planning, training, and as a general conversation piece, whether hung on a wall of an office, hangar, or home. These 3D raised relief AeroCharts are available unframed or framed (black aluminum, natural oak, medium oak, or dark oak). How are these three dimensional raised relief maps made? Each raised relief map starts as a map printed on a flat study sheet of vinyl. It is carefully registered over a 3D model that is made from USGS digital elevation model data. The vinyl is heated to make it pliable and
