Using CoGo
Offset
Offset calculates the coordinate
of an offset point (
P
3
) along a
line between two known points
( P
1
& P
2
) at a distance ( D ) along
that line and at a specified
perpendicular Offset .
Press to switch from the right offset to the left offset.
This functionally is similar in the other CoGo functions.
To Line 1
This function calculates a new
point ( P
4
) along a line between
two points ( P
1
& P
2
) that is offset
perpendicular from a third point
(
P
3
). It also displays the distance
(
D
) along that line and the
Offset
distance.
To Line 2
Use this function to calculate a
new point (
P
3
) at a given bearing
(
B
) from a point (
P
1
) that is offset
perpendicular from a second point
(
P
2
). It also displays the distance
( D ) between P
1
& P3 and the
Offset distance between P
3
& P
2
.
Bearing-Bearing
Bearing-Bearing is used to
calculate offset points at
centerline intersections.
P
1
&
P
2
are points on the two intersecting
centerlines and B
1
& B
2
are the
respective bearings of those
centerlines. The right-of-way offsets are entered as
Offset
1
and
Offset
2
. The resultant point,
P
3
is at the intersection of
the two right-of-ways.
Use the button to switch between 4 different offset
scenarios.
