Fieldwork
CSIRO conducts a range of field work for Earth Observation related activities. In particular, ground truthing products generated from EOI and collection of measurements to support calibration and validation.
Fieldwork can include in situ spectral measurements using calibrated instrumentation, such as for validation of hyperspectral satellite imagery, or qualitative measurements to determine mineralogy of regolith materials using a field portable spectrometer.
Example of ground validation of Earth Observation satellite imagery in conjunction with staff from NASA at the Pinnacles Cal-Val Site.
Cimel Sun Photometer deployed at a Western Australian AEROSPAN (Aerosol characterisation via Sun Photometry: Australian Network) site providing aerosol optical thickness, Angstrom component and water vapour of the atmospheric column.
Field validation of surface reflectances using an ASD Fieldspec in the Pilbara region of Western Australia.
Surface reflectance measurements with a contact probe attached to an ASD FieldSpec spectroradiometer in the Pilbara, Western Australia.
Field campaign of measurements with portable field spectroradiometers, Sun Photometers and weather station at the Pinnacles Cal Val site to coincide with a satellite overpass.
Field spectroradiometer measurements at the Lake Lefroy (Western Australian salt lake) satellite calibration and validation site, where a blue tarpaulin has been laid out.
Field measurements with an ASD FieldSpec spectroradiometer in the wheat fields of Mullewa, Western Australia. Measurements coincided with an airborne imaging spectroscopy acqusition.
Measurements of surface reflectance at a bauxite mine in the Darling Ranges of Western Australia for assessment of rehabilitation of vegetation and soils after mining.
