Polygon and arc feature classes are included. Each side of a quadrangle is composed of a single arc, subdivided into 5 arc segments of 1.5'. There is a tic for each quadrangle corner. These data are in a Lambert Conformal Conic projection and coordinate units are feet. The arcs are coded with latitude or longitude in decimal degrees.
Polygons have no user-defined attributes.
