polar method surveying

To create e.g. a location plan, the position and height of a point on the object are determined by measuring angles and distances. To do this, the instrument is set up on any prominent point in a local coordinate system. A second prominent point is selected for the purposes of orientation; after this has been targeted the horizontal circle is set to zero (refer to the user manual). If a coordinate system already exists, set up the instrument on a known point within it and line up the horizontal circle with a second known point (refer to the user manual).
