Unit Converter:

Most countries have now adopted a metric system of measuring units but often we find ourselves facing measurements in traditional systems which can be converted easily if the conversion factors are known. CoGeo has a large library of these factors for your reference and can be added to and customised to suit.

Trapezoidal Area/Volume:

A popular method of calculating areas is by a series of vertical measurements at intervals across the section. The trapezoidal method simply multiplies the base length by the height where Simpsons rule implies parabolic arcs. Volumes can be measured in a similar way using the area of sections along the length of the item to be quantified.

Quantity Surveyors have the responsibility on a construction project of making sure the contractor is paid appropriately for the work they do and that any sub contractors work is measured fairly and accurately. This often involves the complex measurement of very large earthmoving operations or may simply be repetitive tasks of computing areas from sets of coordinates.

DTM Volume:

Complex shapes are popularly measured using a triangle mesh often referred to as a Delaunay triangulation. The two surfaces are modelled separately using this mesh and contours are shown so that the resulting model can be verified and edited if necessary. The models are then merged together and broken down into many individual prisms whose volumes are calculated and added together to give the total cut and fill between the surfaces. In version 1.1 we have added a render view, which allows the user to spin the model around and view it from any direction as a solid model or virtual reality.
