Inputs

The following table lists all ENVI_FilterTiePointsByGlobalTransformWithOrthorectification inputs.
Mandatory (optional) settings are listed as Required = True (Required = False).

Name Required Default Valid Values Description
file_types False N/A string GBDX Option. Comma seperated list of permitted file type extensions. Use this to filter input files -- Value Type: STRING[*]
output_tiepoints_uri_filename False N/A string Specify a string with the fully-qualified path and filename for OUTPUT_TIEPOINTS. -- Value Type: STRING
input_orthorectified_tiepoints True N/A See ENVITIEPOINTSET input type This is a reference to the input orthorectified tie points. It is typically generated by GenerateTiePointsByCrossCorrelationWithOrthorectification or GenerateTiePointsByMutualInformationWithOrthorectification task. -- Value Type: ENVITIEPOINTSET
error_threshold False 5.0 string Specify the maximum error to allow for each tie point. -- Value Type: DOUBLE -- Default Value: 5.0
fitting_transform False "first-order polynomial" string Specify the transform to use when automatically filtering tie points. -- Value Type: STRING -- Default Value: "First-Order Polynomial"
input_tiepoints True N/A See ENVITIEPOINTSET input type This is a reference to the input tie points. -- Value Type: ENVITIEPOINTSET
