Aim

After this tutorial, you will be able to export pre-recorded flight data to CIR and stitch the view to one compound map. This a quite simple approach where only one view at the time can be stiched.

Requirements

Prior getting started you will need

  • Cubert Utils Fuchsia (v. 2.2.0 or newer, available for download here)
  • Flight data from a Cubert Hyperspectral camera (please find sample data here)
  • Microsoft ICE (see  EXTERNAL LINK)

Demo data

  • Berlin Flight 3 (REFERENCE) CU3 DATA
  • Trial version Cubert Utils 2.2.0 or newer

Steps

  1. Open Cubert Utils Touch
  2. Enter gallery mode
  3. Browse to the flight data (only one flight)
  4. Open one file in details mode and select “Processing Mode” = “Reflectance” and View = “CIR”
  5. Navigate back to the overview and open export dialog. Select:
    • Processing Mode = Reflectance
    • Pan-Sharpen = 0%
    • Format = Multi-Channel-Tiff
    • Export All = selected
    • advanced / Channels = “450”
    • Interpolation Mode = “Bicubic”
    • Pan Image Separately = unchecked
    • Pan Image To cube = uncheded
    • Write Labels = unchecked
    • Export view = checked
    • Overwrite Source = unchecked
    • Force Re-Process = unchecked
    • Force Current References = unchecked
    • Confirm and wait for export to finish
  6. Start Microsoft ICE
  7. Select “New Panorama”
  8. Browse to you export directory (Default:../../export relative to your data location)
  9. Mark all files ending with “_view.tiff”, confirm to open (hint: order by size)
  10. Select “Simple Panorama and press “Next”, wait for the step to finish
  11. Select the desired orientation and press “Next”
  12. Select the desired crop area and press “Next”
  13. In the “Image” tab select
    • scale = 100%
    • File Format TIFF
      and press “Export to disk”

Conclusion

Congratulations! You have created you first stitched map based on hyperspectral data. You can repeat the process for different views on the data, e.g. CIR.
