Measuring Hidden Points

Bearing & Distance
One point must be known. It
• may already exist in the job.
• may be manually occupied during the hidden point measurements.
• may be manually typed in.
The distance and the bearing from the known point to the hidden point are to be determined.
An auxiliary point helps compute the bearing which might not be known. The auxiliary point
may be measured in the direction from the known point to the hidden point.
