# Point Resection

You can use a series of observations to resect a point position.

Rules:

1. All resection observations must appear sequentially. (no gaps)

2. You must have a minimum of one obs and a maximum of 10 observations.

## Calculation Method

Observations can be with a bearing only or a bearing and distance.

A minimum of three bearing observations are required to compute the resection.

A minimum of two bearing and distance observations are required for the calculation.

If more than three obs are present, a least squares solution is computed for the postion.

**Point**

You can enter the point number to be created, or leave blank to auto allocate a point number

**Observations**

- Point - Enter the Source Obs point number.

You can click any point on the screen for this
- Bearing - Enter the Bearing (DDDMMSS) for the obs.

You can click on a line in the job to adopt that bearing
- Distance - Enter the Distance value if known.

You can click on a line in the job to adopt that disance

**OK**

Press Ok to Compute the Resection
