Inputs

The following table lists all ENVI_AdditiveMultiplicativeLeeAdaptiveFilter 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[*]
input_raster True N/A See ENVIRASTER input type Specify a raster on which to perform additive and multiplicative Lee adaptive filtering. -- Value Type: ENVIRASTER
input_raster_format False N/A See ENVIRASTER input type Provide the format of the image, for example: landsat-8. -- Value Type: STRING
input_raster_band_grouping False N/A See ENVIRASTER input type Provide the name of the band grouping to be used in the task, ie - panchromatic. -- Value Type: STRING
input_raster_filename False N/A See ENVIRASTER input type Provide the explicit relative raster filename that ENVI will open. This overrides any file lookup in the task runner. -- Value Type: STRING
input_raster_raw_output False False See ENVIRASTER input type Provide True to output an ENVI Binary instead of a tif. -- Value Type: STRING
window_size False 3 string Specify a square filtering window size. -- Value Type: UINT -- Default Value: 3
multiplicative_noise_mean False 1.0 string Specify the multiplicative noise mean. -- Value Type: FLOAT -- Default Value: 1.0
additive_noise_mean False 0.0 string Specify the additive noise mean. -- Value Type: FLOAT -- Default Value: 0.0
noise_standard_deviation False 0.25 string Specify the noise standard deviation. -- Value Type: DOUBLE -- Default Value: 0.25
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_AdditiveMultiplicativeLeeAdaptiveFilter 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.
