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.
The following new ENVI tasks are now available on the GBDX platform, starting with this v1.5.0 update:
|ENVI_BinaryAutomaticThresholdRaster||Create 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_BufferZone||Create a buffer zone image from a classification raster.|
|ENVI_CalculateGridDefinitionFromRasterIntersection||Create a grid definition from an array of rasters whose spatial extent encompasses the area where the rasters overlap.|
|ENVI_CalculateGridDefinitionFromRasterUnion||Create a grid definition from an array of rasters whose spatial extent encompasses all of the rasters.|
|ENVI_CalculateRasterThreshold||Calculate a threshold value for each band in a raster, as input to ENVIBinaryGTThresholdRasterTask or ENVIBinaryLTThresholdRasterTask.|
|ENVI_DimensionalityExpansionRaster||Create 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_DimensionalityExpansionSpectralLibrary||Perform dimensionality expansion on a spectral library to match the data space of a dimensionality expansion raster.|
|ENVI_ExportRasterToCADRG||Export a three-band byte raster to CADRG format. A NITF/NSIF Module license is required to write to CADRG format.|
|ENVI_ExtractROIsFromFile||Open one or more ROIs from a specified location.|
|ENVI_FlatFieldCorrection||Apply Flat Field atmospheric correction to a raster.|
|ENVI_GenerateContourLines||Generate contour lines from an input raster and convert them to a shapefile.|
|ENVI_GenerateIndexArray||Create an array of numbers (typically used with contour lines).|
|ENVI_GetColorTable||Get an array of red/green/blue (RGB) values from a specified IDL color table name.|
|ENVI_IARReflectanceCorrection||Apply Internal Average Relative Reflectance (IARR) correction to a raster.|
|ENVI_PixelStatistics||Compute 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_TopographicShadingUsingHLS||Blend an HLS (hue/lightness/saturation) color representation of a DEM with a topographic feature such as shaded relief.|
|ENVI_TopographicShadingUsingHSV||Blend an HSV (hue/saturation/value) color representation of a DEM with a topographic feature such as shaded relief.|
|ENVI_TopographicShadingUsingRGB||Blend an RGB color representation of a DEM with a topographic feature such as shaded relief.|
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 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.
A discrepancy between documentation and task definitions on ENVI_ExportToShapefileTask has been fixed.
The following API endpoints will be retired from the GBDX Platform on Monday, April 22, 2019. This means you will not be able to access or run calls against these API endpoints.
- VectorService ESRI API Endpoints
- VectorService Non-Index-Based API Query Endpoints
Our reports indicate these API endpoints are not in use, so there should be no customer impact. GBDXtools and GBDX Notebooks will not be affected.
Index-Based API Endpoints will continue to be available. Write API Endpoints will also not change. If you have any questions or concerns, please email email@example.com as soon as possible.
The following tasks have been retired:
-Automated Land Cover Classification (task name = lulc)
- Built-up Extent (protogenV2PANTEX10)
Please contact gbdx-support @digitalglobe.com if you have any questions.
GBDX Domain Updates:
- nvidiag2 has been updated to the latest driver version
- nvidiap2 has been updated to CUDA 10.0
See GPU Specs for more information
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'.
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.
This file update will take place during a brief maintenance window on Thursday, September 13, 2018.
There will be no downtime or impact to GBDX services.
The 2018 DEM file will now be default file. TO use the default DEM, no action is required.
To continue using the 2016 DEM file, specify it as an input using the ortho_dem_specifier optional setting in the AOP_Strip_Processor task.
File Names and Locations
2016 DEM: s3://dgdem/DEM_2016_08_12.txt
2018 DEM: s3://dgdem/DEM_2018_04_06.txt
Thursday, September 13th at 9 PM MST, the workflow system will be down for maintenance. Workflows cannot be submitted during that time. See the Platform Status Notification.
The ENVI® Task Engine software on the GBDX platform has been updated with a new v1.3.3 version for all ENVI tasks on GBDX. The updates are described below.
Note: The ENVI task engine on GBDX uses ENVI version 5.5 available from Harris Geospatial Solutions

- ENVI® Image To Image Registration
The following ENVI tasks have been removed from direct access on the GBDX platform and instead combined into the ENVI® Image Coregistration Workflow Task:
- ENVI® Image To Image Registration
- The ENVI Raster Statistics task documentation has been updated with an end-to-end Python workflow script in the QuickStart tutorial.
- The ENVI® ROI Statistics task documentation has been updated with an end-to-end Python workflow script in the QuickStart tutorial.
- The ENVI® GeoJSON to ROI task documentation has been updated with an end-to-end Python workflow script in the QuickStart tutorial.
- A bug has been fixed where GeoJSON data was not being read properly
- A bug has been fixed where string outputs were not being created properly when linking tasks together.
GBDX University has been updated with some design and navigation improvements. Updates include:
A cleaner landing page design
An additional layer of navigation in the left navigation pane
User documentation and API reference material each have their own section The API reference section uses a new 3-column format
The Validate Token request was updated to include client ID for tracking purposes.
The Postman collection has been updated to reflect recent API retirements.
The GBDX Thumbnail Service API was removed
All references to previously deprecated APIs were removed
The "submit a workflow" example was updated The Postman Environment file was updated to remove API key since it's no longer used for GBDX Authentication.
A number of components and tasks have been retired from the GBDX platform during July. Please see the GBDX Deprecation Schedule for a complete list.
The ENVI® Task Engine software on the GBDX platform has been updated with a licensing maintenance deployment of new v1.3.2 version for all ENVI tasks on GBDX. The new v1.3.2 version of ENVI tasks will be the active supported version of the ENVI® Task Engine software on GBDX effective immediately. All workflows that run ENVI tasks without explicit task version execution will continue to operate since the latest v1.3.2 version will automatically be executed. Any existing workflows with explicit ENVI task version execution of v1.3.1 or older will need to be updated by either removing the explicit task version execution (recommended) or updating the explicit version being executed to "1.3.2". For more information on GBDX task versioning behavior in workflows please consult the documentation on this topic:
