Measurements at 1 point, 1 date :

Greek monitoring

Evaluation: Poor, no spatial info, no procedural info

Contents:

  • Excel Data File
    • No spatial information
    • Depth info in Excel
    • Contains conversion factors for specific properties
    • UoM as additional row under ObsProps
    • No procedural information
  • Metadata file
    • Only administrative info, responsibles

Measurements at multiple points (x,y are there), 1 date :

Evaluation: Poor, only relative spatial information, no real coordinates. UoM difficult as mixing in Property. Does include procedure

Contents:

  • Excel Data File
    • readme tab contains all columns with description, UoM and methodology
      • includes depth information for all locations
      • Site location is not provided in readme, only name of site "Itatinga Experimental Station, University of São Paulo"
      • spatial information provided in m, but no information on the origin
      • issues with UoM as usually includes compound, should be shifted to ObsProp.
        • Not UoM "mg C g-1 soil DW h-1", ObsProp "Glucose-induced respiration rate"
        • Should be UoM "mg g-1 h-1", ObsProp "Glucose-induced respiration rate as C in soil DW"
    • data file: fairly normal
      • one column includes %, other just provide a fraction, though UoM same
  • Metadata file
    • in addition to administrative metadata, quite a bit of descriptive content.
    • Includes keywords, partially even from AgroVoc.

Cacao

Evaluation: Good!

Contents:

  • CIV_Cacao_sols Nguessan.txt - metadata
    • Contains ObsProp, UoM and method for all columns
  • CIV_Cacao_sols Nguessan.xlsx - data
    • coordinates seem to be WGS84 (or related)
    • some values are colored (red or green), unclear what this means

Finland Soil - same as Greek monitoring

Evaluation: Poor, no spatial info, no procedural info

Contents:

  • dataset
    • many values include "<", e.g. "< 1"
  • metadata
    • administrative data full stop

Measurements at different times, at 1 point (no spatial info) :

Soil 4-m profile data

Evaluation: Poor, no spatial info, no procedural info

  • dataset
    • no spatial information, only sample ID
    • ObsProps explained for first table, other tables without explaination
  • No additional metadata provided

Measurements at multiple points and multiple times (will we have this situation in the Mission Soil projects ? I can investigate during MS week the 5-6 nevember) :

Long term monitoring of near surface soil temperature i

Evaluation: Excellent!!! Only issue is that some bits are nested in further files, some in french

  • data
    • additional metadata file in data, includes valuable information, e.g. CRS
      • links to further metadata files, includes
        • measurement design
        • information on the sensor model
        • accuracy
        • UoM is hidden, but there
    • file with spatial information of all locations (CRS described above)
    • Data file clean, ID, Timestamp, Value

  • metadata
    • mostly administrative, but does include keywords, more than others

Measurements with no spatial and temporal information (located in the article probably):
