{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
& C.
