\Ca*das"tral\, a. [F.]
Of or pertaining to landed property.
{Cadastral survey}, or {Cadastral map}, a survey, map, or
   plan on a large scale (Usually 1/2500 of the linear
   measure of the ground, or twenty-five inches to the mile
   or about an inch to the acre) so as to represent the
   relative positions and dimensions of objects and estates
   exactly; -- distinguished from a topographical map, which
   exaggerates the dimensions of houses and the breadth of
   roads and streams, for the sake of distinctness. --Brande
