Full description

The National Spectral Database (NSD) houses data from Australian remote sensing scientists. The database includes spectra covering targets as diverse as mineralogy, soils, plants, water bodies and various land surfaces.

Currently the database holds spectral information from multiple locations across the country and as the collection grows in spatial / temporal coverage, the NSD will service continental scale validation requirements of the Earth observation community for satellite-based measurements of surface reflectance.

Value: Curated spectral data provides a wealth of knowledge to remote sensing scientists. For other parties interested in calibration and validation (Cal/Val) of surface reflectance products, the Geoscience Australia (GA) Cal/Val dataset provides a useful resource of ground-truth data to compare to reflectance captured by Landsat 8 and Sentinel 2 satellites.

The Aquatic Library is a robust collection of Australian datasets from 1994 to present time, primarily of end-member and substratum measurements.

The University of Wollongong collection represents immense value in end-member studies, both terrestrial and aquatic.

Scope: The NSD covers Australian data including historical datasets as old as 1994. Physical study sites encompass locations around Australia, with spectra captured in every state.

Data types:
- Spectral data: raw digital numbers (DN), radiance and reflectance. 
- From spectral bands VIS-NIR, SWIR1 & SWIR2: wavelengths 350nm - 2500nm collected with instruments in the field or lab setting.

Notes

Purpose
- Provide access to curated Australian spectral data, including Geoscience Australia's Analysis Ready Data (ARD) field Calibration and Validation datasets. - Promote the highest-quality metadata collection and uptake to get the most value out of remote sensing datasets. - Provide an ongoing & managed repository for past, current and future remote sensing studies.
