Data export

Cubert’s hyperspectral data is recorded in the special cu3 / cu3s format. This retains all data needed for re-processing, but is also memory-efficient.

For working outside Cubert’s software either the SDK or export can be used. The export options are available via Touch or via command-line options. 

Export to ENVI

When exporting to ENVI, all channel wavelengths and axis labels are written to the .hdr file. When using pan-sharpening, a plot average is set accordingly. 

Export to TIFF

The tiff export comes in various flavours. Files can be exported as one-file-per-channel or as multi-channel-tiff. Also, the panchromatic image can be added to the tiff, or exported as a separate file. All exported tiff files contain EXIF header, GPS header (if GPS was available) and XMP header.

Export of views

The measurements can be processed using the open cuber “user plugin” format. This XML-based format allows the definition of an mathematical expression tree, including perClass Mira / perclass SDK classifiers. The results of these views can be exported to disk directly. Images are written as Tiff (with EXIF, GPS and XMP meta-data), non-image data is written as csv-files.

Example ENVI:

Export of a so called pan image to ENVI with 100% pan-sharpening, having the pan image as the first channel.

Command: CubeExport.exe -i flower.cu3 -o export -s 1 -p ENVI

Example Agisoft Metashape:

Export whole directory as tiff for Agisoft Metashape (no pan-shaprening, pan-image separately):

Command: CubeExport.exe -i “flight_dir” -o export -f TIFF -f MultiChannel

Example export to CAI (chlorophyll absorption index):

Command: CubeExport.exe -i flightB_008.cu3 -o export -s 1 -p VIEW -u myCAI.xml
