ENVI® Pixel Scale Resample Raster

This task resamples a raster to different dimensions by multiplying the pixel size by a scale factor.

GBDX Registered Name: ENVI_PixelScaleResampleRaster
Provider: Harris Geospatial Solutions

Inputs

The following table lists all ENVI_PixelScaleResampleRaster 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
pixel_scale True N/A string Specify a two-element array of positive values that define how each pixel will be resized. Setting this keyword can result in the resampled raster having slightly different geographic extents than the source raster. Scaled pixels may not exactly cover the same geographic area as the original pixels. The upper-left corners will coincide while the right and bottom edges will be scaled by a sub-pixel amount. -- 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_PixelScaleResampleRaster 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.
