Orbit Path Node

The Orbit Path dialog gives access to two groups of additional orbit path parameters, time- constant shift and time-constant rotation. These parameters model the difference between the provided orbit path and the actual path in space and will be determined during the adjustment. Note: The time-constant rotation is experimental and should not be used! A node is created either during the Image import or direct Import of Metadata via the Image Node.

Double click on the orbit path node will open the following dialog.

Orbit Path dialog

This dialog can be used as a viewer for the additional orbit path parameters and to select adjustable parameters. To change the reference system in which the parameters are shown toggle between Show in reference system or Show in orbital system. To determine the additional parameters tick time-constant shift or time-constant rotation . Currently you can only select or deselect all three parameters per group. Single selection is not yet supported.

The accuracy column can be used to introduce a priori accuracy information for the additional parameters. The column Parameter shows the adjusted (or default) value of the parameters and its standard deviations. By pressing Apply to all the selected parameters and introduced accuracy information will be stored in all orbit paths in the project.

Reset Parameter resets adjusted parameters to their default deviations and accuracy information. Reset all resets all orbit paths in the project.

To the rename the orbit path click with the right mouse button on the node and select Rename. Note: Barista uses the name to automatically determine whether orbit paths can be shared between different Pushbroom scanners. Therefore, only change the name if you load Pushbroom scanner metadata manually via Import of Metadata.
