The purpose of this study is to analyze the possibilities and limitations of using ground-based spectroradiometry methods to create spectral libraries of northern plants and apply them to interpret satellite images in the area of technogenic impact around Monchegorsk (north-west of European Russia) and Noril’sk (north of central Siberia). We compared various methods for measuring plant samples, examined the influence of measurement conditions, of plant species, their age, differences in habitat conditions, and level of disturbance. To make a database of the spectral signatures of plants and compare different instruments, we measured their reflectance with a SkyeInstruments SpectroSense2+ 4-band spectroradiometer and an ASD FieldSpec 3 Hi-res hyperspectroradiometer.
