Beyond NDVI- Spectral indexing of biomass

Abstract

The use of both terrestrial and satellite sensors often lacks the specific knowledge that makes them more effective. There are many reasons for this, one of them is agricultural digitalization to facilitate data availability and shortened automatic spectral indexing, but interpretation requires special remote sensing and agricultural knowledge. The absence of this complex knowledge, will result in misleading or incorrect solutions and on the other hand the existing technical possibilities cannot be exploited by the farmers. The application and calculation of the wide and narrow band channel VIs were presented on two agricultural test areas. The purpose of this publication is to briefly introduce the technical capabilities of vegetation indices based on a Hungarian test site and thereby reduce potential misinterpretation.
