At some extent refers to any area that is tangential into a stage surface area in a presented area. The horizontal line parallels the plumb line.
immediate levelling , in which you measure discrepancies in elevation directly. This can be the mostly utilised technique;
The levelling basic principle is to get a horizontal line of sight with respect to which vertical distances in between destinations over and under this line of sight are calculated.
