In a profile leveling process, in between two turning points(TPs), there are many intermediate stations that we take readings to find out the elevations of the those stations. These readings can be taken using a level, a theodolite or a total stations. Problem is that how to find out the elevation of those stations. Using a bench mark and its given elevation it can be learned from the following example. The method used is generally known as the Height of the Instrument method. If you have any doubt please let me know in the comment box.
