How are End Area Volumes calculated in InRoads?


The End Area Volumes calculation is based on the traditional end-area volume calculation to compute cut, fill, and net volumes using a series of cross sections along a previously defined alignment:

Using this method, two end areas are averaged over the entire length between them:


This method is the least accurate of all the volume calculations, however it is widely accepted by engineers/contractors. Furthermore, the accuracy of the end area calculation is indirectly proportional to the cross section interval.
