Deed Plotter

Course

One leg of the boundary. Every course has a bearing (direction) and a distance. Straight courses use a quadrant bearing; curves use a chord bearing plus radius and central angle.

Bearing

The direction of travel expressed as an angle from north or south toward east or west. Example: N 45°30'15" E means start facing north, rotate 45° 30' 15" toward the east.

Passing Call

A course along an adjoining deed line, road, or creek where the bearing comes from the adjoining record rather than being explicitly stated. Check "Passing call" to include the distance in your perimeter without needing the bearing.

Point of Beginning

The starting corner of the description. The boundary should close back to this exact point. A closure error means the last course doesn't return to the POB.

Curve Call

A curved boundary segment defined by radius, central angle (delta), chord bearing, and chord distance. The arc length is calculated automatically from the radius and delta.

Closure Error

The gap between the last computed point and the POB. A closed deed has 0.00 ft error. ALTA surveys require 1:10,000 or better precision.
