To select the starting point, click on a point on the screen, or enter the point number at the keyboard. Type in the point number and press ENTER, TAB or Down Arrow to move to the next field

To select the ending point, click on a point on the screen, or enter the point number at the keyboard. Type in the point number and press ENTER or TAB to display the bearing and distance.

The bearing from Point 1 to Point 2 is displayed in degrees, minutes and seconds DDD MM’ SS’ format.

The distance from Point 1 to Point 2 is displayed in metres. (Horizontal distance).

This is the difference in heights between the two points as Pt2_height – Pt1_height. Thus a positive number means the line from point 1 to point 2 slopes upwards.

This is the slope of the line from point 1 to point 2. A positive slop means the line slopes upwards from point 1 to point 2.

If the two points lie on a curve, the centre point number will be displayed here. A curve is defined as a curved string segment joining the two points

If the two points line on a curve, the radius of the curve will be displayed here. A curve is defined as a curved string segment joining the two points.

If the two points line on a curve, the arc distance of the curve joining the two points is shown here. A curve is defined as a curved string segment joining the two points.
