Your supplied spectral data, curated

The National Spectral Database (NSD) houses best-practice spectral data collected by Australian remote sensing scientists from multiple locations and institutions across the country. As the collection grows the NSD will service continental scale research for the Earth observation community and support application such as the validation of satellite-based measurements of surface reflectance.

The National Spectral Database targets as diverse as soils, vegetation, waterbodies, coral, macro to micro algae, seagrasses and land surfaces.

The database also includes field-based data routinely collected by Geoscience Australia’s Digital Earth Australia program for calibration and validation measurements, as well as spectral data previously hosted by the University of Wollongong.

Why collate spectral data?

  • Provide a wealth of knowledge to remote sensing scientists
  • Compare EO reflectance data to a useful resource of ground-truth data
  • Curated data going back to 1994
