Question

A common problem in surveying is to determine the altitudes of a series of points with respect to some reference point. The measurements are subject to error, so more observations are taken than are strictly necessary to determine the altitudes, and the resulting overdetermined system is solved in the least-squares sense to smooth out errors. Suppose that there are four points whose altitudes

Answer 1

During light downpour or day off, teams can work; be that as it may, at whatever point the downpour or snow is influencing perceivability or there is lightning, a field group ought not be working.
