Spectral resampling: Missing wavelength definition for spectral raster layer: raster

[Maesiu]

Hi, The spectral resampling tools (to any sensor) seem not to work properly.

Error: Missing wavelength definition for spectral raster layer: raster

The error appears for all .bsq files I use as input. The wavelength definition should be correct in the .hdr file:

ENVI description = { E:/20220530_AVIRIS_NG_Irlbach/Irlbach/400_2500nm_Cut/ang20210530t101445_rfl_wlCut.bsq} samples = 663 lines = 2837 bands = 419 header offset = 0 file type = ENVI Standard data type = 3 interleave = bsq byte order = 0 map info = {UTM, 1, 1, 332499.642028, 5419368.76286, 5.3, 5.3, 33, North,WGS-84} coordinate system string = {PROJCS["unnamed",GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["WGS_1984",6378137.0,298.257223563]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["Transverse_Mercator"],PARAMETER["False_Easting",500000.0],PARAMETER["False_Northing",0.0],PARAMETER["Central_Meridian",15.0],PARAMETER["Scale_Factor",0.9996],PARAMETER["Latitude_Of_Origin",0.0],UNIT["Meter",1.0]]} band names = { Band 1, Band 2, ...

Hi @Maesiu, please share your ENVI file.

ang20210530t101445_rfl_wlCut_minisubset_TO_NoOverlapMEAN.zip

I would like to resample ang20210530t101445... into 20240501_102037_01_NoOverlapMEAN...

ok, further errors to be reported. The first error disappeared although I do not know why?

If I use an .hdr-file as FWHM and wavelength source:

Thank you for looking into it! Greetings, Matthias

Hi @Maesiu, your ENVI header has a typo. Nanometer (without the letter "s" at the end) is incorrect.

See: https://www.nv5geospatialsoftware.com/docs/ENVIHeaderFiles.html

Nevertheless, I will support the spelling without a the "s" in the future.
