The planimeter is a mechanical device used for determining the area of many shape of figure plotted to unknown scale. It's design is based on the principle that the amount the roller turns is a measure of the area

Simpson's One Third Rule is based on the assumption that the curved boundary consists of parabolic arcs, where each arc is continuous over three adjacent offsets that are equally spaced. Because of this assumption the rule is only applicable when there is

The assumption made in using the Trapezoidal Rule is that the ends of the offsets in the boundary line are assumed to be connected by

The double meridian distance of the last course of a closed traverse is numerically equal to the

The meridian distance of a line is defined as the

The hectare is the most commonly used unit of area for large tracts of land. It is equal to

In plane surveying, the area of a tract of land is taken as its projection up on a horizontal plane. However, areas of much larger tracts of land such as a country or a continent are taken as the

Whether the sides of a closed traverse with unknown activities are adjoining or non-adjoining, it must be definite that the algebraic sum of the latitudes and the algebraic sum of the departures must be zero

When the two sides of a closed traverse are non-adjoining, the determination of the unknown quantities is undertaken with an added graphical solution. For example, a line for lines may be moved from one location to a second location parallel with the first. This principle is adapted since the

When the length or direction of a line within aclosed traverse cannot be determined by field observation, these missing quantities may be determined analytically to obtain a complete set of notes for the traverse provided
