Field spectroscopy is an in-situ method for characterising the reflectance of natural surfaces and thereby provides reference data for the calibration of airborne and satellite sensors. In addition, the method provides a means of scaling-up measurements from small areas (e.g. leaves, rocks) to composite scenes (e.g. vegetation canopies), and ultimately to pixels.
Measure reflectance of surfaces of vegetation types and other thematic classes in the field
Compare reflectance measurements from the field to reflectance values in radiometrically pre-processed EO data
