Geospatial Approaches to Monitoring the Spread of Invasive Species of Solidago spp

Štefan Koco, Anna Dubravská, Jozef Vilček, Daniela Gruľová
2021 Remote Sensing  
We can also say that due to the spectral proximity of the surrounding vegetation, the spectral resolution in four spectral bands is insufficient for the classification of multispectral records in the case  ...  of Solidago spp. and cannot replace the advantages of high spectral resolution hyperspectral imaging, which significantly refines the feature space for Solidago spp. and the surrounding vegetation.  ...  Subsequently, combining data from different types of sensors, such as optical and synthetic-aperture radar (SAR), improves classification accuracy [50] .  ...
