In this study an investigation was done to find out how useful the spectral information from Landsat TM is, and if the reflectance values has any connection the needle nitrogen concentration of Norway spruce (Picea abis (L.) Karst.). Moreover, an evaluation of the PROSPECT model was done, both to find out the importance of each input parameter and to find out how they affect the reflectance. A fieldwork was carried out in the spring of 2000 where ten different Norway spruce stands in Scania were visited and various parameters measure...
