Setting up a station using multiple point resection
A resection sets up the station using angle/distance measurements to known points.
You can use a maximum of 10 points in a resection. Measurements can be distance and
angle, or angle only. Calculation starts automatically when enough measurements are
taken.
You can delete poor observations and recalculate if necessary. You can also select the
BS point.
Note –
If the angle between known point 1 and known point 2 (measured from the station
point) is extremely acute or extremely oblique, the resulting solution will be less reliable
geometrically. For geometric reliability, select known point locations (or station point
locations) that are widely spaced.
