Name

Name of the station.

Type

Type of control or check point, which can be 3D, horizontal or vertical.

Latitude

Known latitude of the station.

Longitude

EllHgt

Known ellipsoidal height of the station.

HzSD

Standard deviation of the known horizontal coordinates. Applies only to 3D and horizontal control points.

VtSD

Standard deviation of the known vertical coordinate. Applies only to 3D and vertical control points.

dE

Easting residual between input coordinate and traverse solution at check point.

dN

Northing residual between input coordinate and traverse solution at check point

dH

Height residual between input coordinate and traverse solution at check point

Right-click Options in the Control / Check Points Window

The following options are available by right-clicking on a control or check point:

View Info

Displays the Information box for the point.

Edit

Allows for editing of known coordinates via the Add / Edit Control Point window.

Toggle between Control / Check

Switches status between control point and check point.
