General

Name

Name of the control point (as it appears in Quality Report, Control Point Editor, 3D Window, etc.).

Point Type

Select the point type: control point, tie point, or check point.

Auto-GCP

Automatically identify this control point’s marker in your photos and mark the photos in PhotoMesh accordingly. This will not override any manual marking of control points. See "Marking Control Points in Photos" step ‎9 in this chapter for more information.

Exclude

Select the check box to exclude the control point from the project. See "Excluding Control Points" in this chapter for more information.

Visible

Select the check box to make control point visible in project. See "Hiding Control Point Symbols" in this chapter for information.

AT Tile

AT Tile in which this control point is included.

Sampled Photos

Number of photos in which this control point was marked. If fewer than three photos were sampled, this field is marked in red (Read-only).

Calculated Photos

Number of photos in which the position of this control point was calculated (Read-only).

Horizontal Accuracy (meters)

Accuracy of the control point’s X and Y coordinates. The AT is adjusted to the control point within the specified accuracy margin of error. This field is not displayed in the Add New Control Point dialog.

Vertical Accuracy (meters)

Accuracy of the control point’s altitude. The AT is adjusted to the control point within the specified accuracy margin of error. This field is not displayed in the Add New Control Point dialog

Horizontal Error

This field is only displayed in the Control Point Editor. If the horizontal error is greater than the margin of error defined by the Horizontal Accuracy value, this field is marked in red (Read-only).

Vertical Error

This field is only displayed in the Control Point Editor. If the vertical error is greater than the margin of error defined by the Vertical Accuracy value, this field is marked in red (Read-only).

Sampling Error

This field is only displayed in the Control Point Editor. If the sampling error is greater than 1 pixel, this field is marked in red (Read-only).

X

East-west coordinate of the control point.

Y

North-south coordinate of the control point.

Altitude

Altitude of the control point in meters.

Coordinate System

Coordinate system of the control point. Click Select  to set a different coordinate system. See "Coordinate System" in the "Basic Concepts" chapter for more information.
