Open Traverse
The inputs of starting azimuth and coordinates are first made.
Nex
i, key in the included angles at individual points and
distances.
As a result, the azimuth and coordinates can be found .
Radiate Traverse
Key in starting azimuth and coordinates.
Next, enter the included angles and distances from st arting
points.
[ Example)
(Open traverse)
As a results, the azimuth and coordinates can
be
found .
