Field spectroradiometer measurements have been collected at several locations across Australia (formally known as the AusCover Supersites) to relate field based measurements to satellite data products, such as Landsat and MODIS NBAR products. The Hyperspectral ground-based data is used for calibration and validation of at-surface reflectance of airborne hyper-spectral image data. Once the at-surface reflectance values of the hyper-spectral image data have been validated, the data can be used for up-scaling to medium spatial resolution Landsat and MODIS data for cal/val of NBAR products.

Data Creation
Sampling Strategy:
Data is typically collected from standardised calibration targets (white, grey and black) laid out in an open area within or nearby the site. Data is collected in a zig zag pattern of points over the target at approximately 1 m intervals. Natural features (roads, soils, grass, irradiance) are also collected opportunistically.
