Parameter descriptions

InputText: Input OrthoEngine project file

Specifies the path and file name of the input OrthoEngine project file.

Image ID

Specifies the image identification name in the project file to which the GCPs are exported.

The following formats are acceptable:

• S129
• S129.pix
• C:\Projects\Demo Data\S129.pix

Output: Output file name

Specifies the output PCIDSK file that will contain the exported GCP segment for IMAGE_ID (Image ID). If this parameter is not specified, the GCP segment is exported to the file that is referenced in the project file and that is associated with IMAGE_ID. If this is not a PCIDSK file, a linked PCIDSK file with an identical base name is created to accept the GCP segment.

GCP Segment Name

Specifies a name (up to 8 characters) for the output GCP segment. If a name has not been specified, the default name "GCP" is assigned.

GCP Segment Descriptor

Describes (in up to 64 characters) the contents or origins of the output data. If a description is not provided, this parameter is assigned an empty string.
