Distance
type
The type of distances and offsets to be
accepted as input or displayed in the fields,
and used in the calculation.
Grid
Distances are calculated as the trigonometric
distance between the position of two points.
The distance field is
Horizontal distance
.
Ground
Distances are horizontal distances between
two points at the mean elevation parallel to
the ellipsoid of the active coordinate system.
The distance field is
Horizontal distance
(ground)
.
Ellipsoid
Distances are reduced to the ellipsoid. They
are calculated as the shortest distance
between the two points on the ellipsoid. A
scale factor is applied. The distance field is
Horizontal distance (ellipsoid)
.
☞
In the attached coordinate system,
a projection, an ellipsoid and a
transformation have to be defined
to calculate grid, ground and ellip-
soid coordinates.

Activates the use of offsets in the COGO cal-
culations. Editable fields for the offsets are
available in the Input panel of any COGO cal-
culation method.
