Data sections

The Si-Ware Neospectra is a handheld near-infrared (NIR) reflectance spectrometer covering 1350–2550 nm at approximately 2.5 nm resolution, producing 257-element spectral arrays. Unlike the benchtop instruments, Neospectra is used both in the field and in the laboratory. Its observation logs use home: 1 rather than laboratory: 1 to reflect this.

Prerequisites

The neospectra provision must exist from Load utility data.

Notebook cell

In load_ai4sh_spectral_data.ipynb, the Manage Neospectra spectrometer cell runs:

job_file = 'import_data/neospectra/job_neospectra_spectrometer.json'

structured_process_D, scheme_params_D = Initiate_process(notebook_path, scheme_file, job_file)

if structured_process_D is not None:
    Run_process(structured_process_D, scheme_params_D)

Job file

Path: ./ai4sh/import_data/neospectra/job_neospectra_spectrometer.json

{
  "process": {
    "job_folder": "import_data/neospectra/spectrometer",
    "process_sub_folder": "process",
    "pilot_file": "xspatula_add_spectrometer_pilot.txt"
  }
}

Pilot file

Path: ./ai4sh/import_data/neospectra/spectrometer/xspatula_add_spectrometer_pilot.txt

neospectra_spectrometer.json

One entry — one spectrometer record.

Process file

Path: ./ai4sh/import_data/neospectra/spectrometer/process/neospectra_spectrometer.json

{
  "process": [
    {
      "process": "manage_spectrometer",
      "parameters": {
        "provision_id__provision_name": "neospectra",
        "wavelength_unit_id__wavelength_unit_name": "um",
        "wavelength_array": [1350.0, 1352.5, 1355.0, 1357.5, "...257 values total...", 2549.9]
      }
    }
  ]
}

The wavelength_array contains 257 values from ~1350 to ~2550 nm at ~2.5 nm steps. The example above is abbreviated.
