The ENVI® Task Engine software on the GBDX platform has been updated with a new v1.5.0 version for all ENVI tasks on GBDX. This ENVI Task Engine update to GBDX includes an upgrade to the latest ENVI v5.5.2 available from Harris Geospatial Solutions along with an ENVI software licensing maintenance deployment.

New ENVI Tasks

The following new ENVI tasks are now available on the GBDX platform, starting with this v1.5.0 update:

NameDescription
ENVI_BinaryAutomaticThresholdRasterCreate an image where values above a specified threshold are set to 1 and all other values are set to 0. The task uses a predefined thresholding method to create the binary image.
ENVI_BufferZoneCreate a buffer zone image from a classification raster.
ENVI_CalculateGridDefinitionFromRasterIntersectionCreate a grid definition from an array of rasters whose spatial extent encompasses the area where the rasters overlap.
ENVI_CalculateGridDefinitionFromRasterUnionCreate a grid definition from an array of rasters whose spatial extent encompasses all of the rasters.
ENVI_CalculateRasterThresholdCalculate a threshold value for each band in a raster, as input to ENVIBinaryGTThresholdRasterTask or ENVIBinaryLTThresholdRasterTask.
ENVI_DimensionalityExpansionRasterCreate an image that contains an expanded number of bands created from various non-linear transforms. Having additional bands increases the dimensionality of a raster, which can help improve accuracy in some target detection algorithms.
ENVI_DimensionalityExpansionSpectralLibraryPerform dimensionality expansion on a spectral library to match the data space of a dimensionality expansion raster.
ENVI_ExportRasterToCADRGExport a three-band byte raster to CADRG format. A NITF/NSIF Module license is required to write to CADRG format.
ENVI_ExtractROIsFromFileOpen one or more ROIs from a specified location.
ENVI_FlatFieldCorrectionApply Flat Field atmospheric correction to a raster.
ENVI_GenerateContourLinesGenerate contour lines from an input raster and convert them to a shapefile.
ENVI_GenerateIndexArrayCreate an array of numbers (typically used with contour lines).
ENVI_GetColorTableGet an array of red/green/blue (RGB) values from a specified IDL color table name.
ENVI_IARReflectanceCorrectionApply Internal Average Relative Reflectance (IARR) correction to a raster.
ENVI_PixelStatisticsCompute statistics for each pixel in a raster. The result is a new raster where each band represents a different statistic computed from the input raster.
ENVI_TopographicShadingUsingHLSBlend an HLS (hue/lightness/saturation) color representation of a DEM with a topographic feature such as shaded relief.
ENVI_TopographicShadingUsingHSVBlend an HSV (hue/saturation/value) color representation of a DEM with a topographic feature such as shaded relief.
ENVI_TopographicShadingUsingRGBBlend an RGB color representation of a DEM with a topographic feature such as shaded relief.

Functional Updates

  • The EXPORT_AREA and EXPORT_CLASS_CLRS ports were removed from ENVI_ClassificationToShapefileTask.

  • APPLY_SYMBOLOGY and OUTPUT_METHOD ports were added to the ENVI_ClassificationToShapefileTask.

  • OUTPUT_COORDINATE_SYSTEM port has been added to the ENVI_RPCOrthorectificationTask.

Documentation Updates

Documentation has been added for all new tasks and updated for tasks that have changed. The updates are follows:

  • The INPUT_RASTER_RAW_OUTPUT port was removed from the documentation for tasks that did not output a raster.

  • ENVI Task Engine documentation has been updated to reflect the latest ENVI version and a new ENVISTRETCHPARAMETER type has been added.

Bug Fixes

A discrepancy between documentation and task definitions on ENVI_ExportToShapefileTask has been fixed.

New v1.4.0 version of ENVI® tasks on GBDX

The ENVI® Task Engine software on the GBDX platform has been updated with a new v1.4.0 version for all ENVI tasks on GBDX. This minor upgrade adds the ability to specify whether the output format for raster output processing results is ENVI Raster format (.dat + .hdr) or GeoTIFF format (.tif + .hdr).

By default the ENVI task runner on GBDX will automatically convert the output raster from ENVI format to GeoTIFF format. However, an issue converting large raster datasets was recently discovered. In order to provide a workaround, a new optional input port input_raster_raw_output was introduced where a user can specify true to have the task skip the TIFF conversion so the output raster file is the original ENVI Raster format. If the tinput_raster_raw_outputt is set to true the resulting output ENVI Raster format can be used in a multi-task workflow with subsequent tasks by using the input port <task_name>.inputs.input_raster_filename = 'data'.

Update to the Default DEM file on GBDX

Summary
The default DEM file on GBDX is being replaced with a more recent version. The current DEM file is from 2016. The more recent DEM file was created in April, 2018. This will now be the default DEM file called by the AOP_Strip_Processor task.

Date Scheduled
This file update will take place during a brief maintenance window on Thursday, September 13, 2018. 

Operations Impact
There will be no downtime or impact to GBDX services.

Action Required
The 2018 DEM file will now be default file. TO use the default DEM, no action is required.
