TOTAL STATION InstructIon manual

This function calculates the center, the 2D and 3D surface and positive, negative andtotal volume.First, you select the points that are used for the volume calculation. The order in whichyou select the points is not important. Please refer 2D SURFACE chapter about selectionway. PowerTopoLite generates a mesh (triangulation) of the points automatically andcalculates the result based on the mesh.The contour of the points will always be convex. A polygon is generated so that an areamay become the biggest. It is like a rope, which is laid around the points, and then tightens.You have to give the reference height, which is used for volume calculation: the part ofthe volume that is situated below the reference height is called negative volume andthe part above the reference height is called positive volume.NOTE: Selected points should be less than 50 points.NOTE: Relations between each volume and reference height are as follows.In 3D Volume, the case that input reference height is lower than a solidReference HeightPositive VolumeTotal Volume =89
