ENVI® Mapping Resample Raster

This task resamples a raster to different dimensions using column and row mapping.

GBDX Registered Name: ENVI_MappingResampleRaster
Provider: Harris Geospatial Solutions

Inputs

The following table lists all ENVI_MappingResampleRaster 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 the raster to resample. -- 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
row_mapping False N/A string Specify an array of interpolation coordinates for each row of pixels. This array must be the same size as the number of rows in INPUT_RASTER. Use this parameter in conjunction with COLUMN_MAPPING to define a regular grid of interpolation coordinates. -- Value Type: DOUBLEARRAY
column_mapping False N/A string Specify an array of interpolation coordinates for each column of pixels. This array must be the same size as the number of columns in INPUT_RASTER. Use this parameter in conjunction with ROW_MAPPING to define a regular grid of interpolation coordinates. -- Value Type: DOUBLEARRAY
resampling False "nearest neighbor" 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: "Nearest Neighbor"
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_MappingResampleRaster 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.
