Overview

This repo shares the raw (binary), parsed and processed spectral data used to develop the general models of the Swiss mid-infrared (mid-IR) soil spectral library (SSL) in version 1. The spectral measurements and modeling were done at the Sustainable Agroecosystems Group at ETH Zürich. The data and hands-on were compiled at the Swiss Competence Center for Soils (KOBO), and also in my private time. This work was done as a PhD project, in collaboration with the Swiss Soil Monitoring group (NABO) at Agroscope. The associated laboratory analytical reference data needs to be requested from NABO. This version comes along with this open-access publication:

Baumann, P., Helfenstein, A., Gubler, A., Keller, A., Meuli, R. G., Wächter, D., Lee, J., Viscarra Rossel, R., & Six, J. (2021). Developing the Swiss mid-infrared soil spectral library for local estimation and monitoring. SOIL, 7(2), 525–546. https://doi.org/10.5194/soil-7-525-2021

How to fetch and use the data

Because this repository contains both binaries (OPUS files with spectra), and large files (> 100MB), the relevant data are stored on GitHub via Large File Storage (LFS).

On Linux, either install git-lfs with your supported package manager, or follow the instructions on the official Git Large File Storage page. On Debian, you can just use:

sudo apt install git-lfs

On MacOS, you can use Homebrew:

brew install git-lfs

On Windows, you can follow the instructions here, where you are referred to download and execute the .exe file provided here (installer).

To enable it for your local user, you need to only type once to activate LFS on your system:

git lfs install

After this, you are ready to clone this repository, whereby git will resolve and download all large files via LFS.
