Volumes

Volumes Volume calculations for rectangular prism and pyramid are shown below: A truncated pyramid is a pyramid which top has been cut off. If the A1+A2 is almost equal in size then the following formula can be used instead: V = h × (A1 + A2) / 2 A prismoid is as a solid whose […]

Lesson Notes On Areas

Areas Area calculations refer usually to rectangular and triangular shapes. If you need the trigonometric function for calculations click here. There are different ways to calculate the area of the opposite figure. Try to minimise the amount of calculation. The figure could be divided in three distinct areas a=10.31×5.63+ b=6.25×5.76+ c=10.39×4.79 or the whole rectangle […]

Lesson Note On Traverse Computations

Traverse Computations ________________________________________ A. Overview A traverse is a series of connected lines whose lengths and angular relationships are measured. 1. Traverse configuration A traverse is either a loop or a link: Loop Link   begins and ends on the same point begins on one point and ends on another 2. Traverse Type A traverse […]

DGPS

DGPS The DGPS (Differential Geographic Positioning System) Survey These are surveys which are carried out using the differential GPS. It achieves higher positional accuracy by making use of the differential capabilities of two GPS antenna linked by a radio signal. The DGPS Survey main features are: ·         Position is determined by distance from at least 4 satellites ·         […]
