Part of pilot 2 - Improved Food Security and Water Extremes Management

The importance of soils is ubiquitously recognized; they provide essential services such as food production, prevention of land degradation, water quality, and they act as carbon sinks. It has been thus recognized that a spatio-temporal monitoring of soil quality and soil properties is necessary. One of the most important technologies used to monitor soils is soil spectroscopy which utilizes the spectral information of soil samples to derive their properties. For the successful upscaling (i.e. use of Earth Observation tools) of soil spectroscopy it is important to create detailed soil spectral libraries on the ground, which assist in the validation of the sensors as well as development of soil models.

The Regional Soil Spectral Library

The current dataset contains a regional vis-NIR (350-2500 nm) soil spectral library of the region. It contains metadata regarding the soils sampled, their key properties, and their spectral signature. The spectral signatures were obtained using a standardization protocol. The dataset encompasses the following countries and soil properties:

Country Samples SOM Texture CaCO3 pH NO3 EC CEC
Albania 107 107 107
Bulgaria 105 105 105 105 105
Cyprus 96 96 94 96 96 93
Egypt 10 6 4 6 6
FYROM 124 124 124 124
Greece 928 928 928 928 928
Israel 221 106 193 150 137 141
Serbia 63 63 63 63 63 63
Turkey 100 94 98 100 100 100
All 1754 1629 1712 1341 631 991 334 105

Form of the datasets

To assist future researchers using this soil spectral library, the datasets are provided in the following formats:

  • Per country SSLs in .csv format
  • Complete GEO-CRADLE SSL in .csv format

The documentation describing what each column represents may be found in D4.6.
