COGO calculation methods Description
•
the centre point of an arc.
•
an offset point from a distance along,
and offset from, an arc.
•
an offset point from a distance along,
and offset from, a line.
•
a base point on an arc of a known offset
point.
•
a base point on a line of a known offset
point.
•
new points along an arc by segmenta-
tion.
•
new points along a line by segmentation.
Shift, rotate & scale
To calculate the coordinates of new points
using shifts, rotation and scale.
The values for the shift, rotation and/or scale
can either be entered manually or computed
using selected matching points.
For these calculations, points with full coor-
dinate triplets, position only points or height
only points can be used.
Area division
To divide an object by a
•
defined line.
•
percentage.
•
defined size.
Angle
To calculate the angles that are defined by
three points.
Horizontal curve
To calculate the missing parameters of a
curve by the input of the known parameters.
Triangle
To define a triangle by entering the three
