GEODESIA
, is properly that part of practical geometry that teaches how to divide or lay out lands and fields, among several owners.
Geodesia is also applied, by some writers, to all measurements in the field, and as synonymous with surveying.
Geodesia is defined by Vitalis, as the art of mea- suring surfaces and solids, not by imaginary lines, as is done in geometry, but by sensible and visible things; on by the sun's rays, &c.
