Information about the USGS Spectral Library Data Download

This post is about recent updates to the USGS Spectral Library Data Download.

Recently the USGS has removed the previous Spectral Library download service and the new download information is at https://www.usgs.gov/media/files/usgs-spectral-library-data-download-information-docx , which describes the download of the whole archive as a .zip file.

Consequently, the Semi-Automatic Classification Plugin tool to Download USGS Spectral Library can't work.

However, it is still possible to import the USGS libraries using the Import tool.
Following the main steps to import a library:
  1. download the main archive ASCIIdata_splib07a.zip from https://www.sciencebase.gov/catalog/item/586e8c88e4b0f5ce109fccae
  2. create a directory and move one spectral library (name ending with _AREF.txt) and the wavelengths file (file name splib07a_Wavelengths_ASD_0.35-2.5_microns_2151_ch.txt) in it
  3. create a .zip file of this directory which can be imported in SCP.
