ENVI® Radiometric Calibration

This task calibrates an image to radiance, top-of-atmosphere reflectance, or brightness temperatures.

GBDX Registered Name: ENVI_RadiometricCalibration
Provider: Harris Geospatial Solutions

Inputs

The following table lists all ENVI_RadiometricCalibration 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 radiometric calibration. -- 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
output_data_type False "float" string Specify output data type, 16-bit signed integer, 32-bit floating point, 64-bit floating point, 16-bit unsigned integer. -- Value Type: STRING -- Default Value: "Float"
calibration_type False "radiance" string Specify the calibration type. -- Value Type: STRING -- Default Value: "Radiance"
scale_factor False 1.0 string This keyword pertains to radiance only. To output radiance in different units than W/(m^2 sr micrometers), enter a floating-point scale factor to get the calibrated image in your desired units. If you do not specify this keyword, the default value scale factor is 1.0, which will yield a radiance image in units of W/(m^2 sr micrometers). -- Value Type: DOUBLE -- Default Value: 1.0
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_RadiometricCalibration 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.
