ENVI® Cast Raster

This task creates an ENVIRaster from a source raster where pixel values have been cast to a specified data type; for example, unsigned integer or double-precision floating point.

GBDX Registered Name: ENVI_CastRaster
Provider: Harris Geospatial Solutions

Inputs

The following table lists all ENVI_CastRaster 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 an input ENVIRaster. -- 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
data_ignore_value False N/A string Specify a numeric pixel value that will be ignored upon export. The pixel state of the output raster will be the same as that of the input raster, regardless of whether or not it was set. The data ignore value should be different from any other pixel value in the input raster, in order to avoid masking out good pixels during export. -- Value Type: DOUBLE
data_type True N/A string Specify a string indicating the data type to cast the pixel values to. Casting a floating-point raster to integer will truncate the data values. Overflow will occur when the original value is greater than the maximum value for the output data type. -- Value Type: STRING
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_CastRaster 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.
