Plans.—It is obvious that the detail which it is possible to introduceinto a map depends more especially upon the scale to which it is we distinguish between plans, topographical maps, andgeneral maps. The scale of a Plan should be sufficiently large toenable separate houses and plots of land to be clearly distinguished. Ascale of I : 500 would suffice for this purpose, and occasionally even amuch smaller scale, say i : 10,000. As a plan only embraces a very smallarea the sphericity of the Earths surface is not taken into account by thesurveyor
