ENVI® Image To Image Registration

This task performs image to image registration.

GBDX Registered Name: ENVI_ImageToImageRegistration
Provider: Harris Geospatial Solutions

Inputs

The following table lists all ENVI_ImageToImageRegistration 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[*]
warping False "polynomial" string Specify the warping method. -- Value Type: STRING -- Default Value: "Polynomial"
background False N/A string Same parameter as DATA_IGNORE_VALUE, left here for backward compatibility purposes. -- Value Type: DOUBLE
base_raster False "raster 1 from tie points" string Specify which raster from input tie points is used as the base raster. -- Value Type: STRING -- Default Value: "Raster 1 from Tie Points"
full_extent False true string Output the full extent of the warp image instead of the overlapping area only. -- Value Type: BOOLEAN -- Default Value: true
resampling False "bilinear" string Specify the resampling method. Nearest Neighbor: Uses the nearest pixel without any interpolation. Bilinear: Performs a linear interpolation using four pixels to resample, Cubic Convolution: Uses 16 pixels to approximate the sinc function using cubic polynomials to resample the image. -- Value Type: STRING -- Default Value: "Bilinear"
output_pixel_size False N/A string Set the output pixel size in the map unit of the base raster. The default output pixel sizes are the same as those of the base raster. -- Value Type: DOUBLEARRAY
polynomial_degree False 1 string Specify the polynomial degree when using the Polynomial warping method. -- Value Type: UINT -- Default Value: 1
input_tiepoints True N/A See ENVITIEPOINTSET input type This is a reference to the input tie points. -- Value Type: ENVITIEPOINTSET
data_ignore_value False N/A string Specify a unique data value for pixels in the output raster that have a non-zero pixel state value (transparent pixels). -- Value Type: DOUBLE
output_raster_uri_filename False N/A string Specify a string with the fully-qualified path and filename for OUTPUT_RASTER. -- Value Type: STRING

Outputs

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

Name Required Default Valid Values Description
task_meta_data False N/A directory GBDX Option. Output location for task meta data such as execution log and output JSON
output_raster_uri True N/A directory Output for OUTPUT_RASTER. -- Value Type: ENVIURI

Output structure

The output_raster_uri file will be written to the specified S3 Customer Account Location.
