gi-2708	Potůčková, Markéta; Štefanová, Eva	Utilization of BEAM and NEST open source toolboxes in education and research	2010	12	.pdf	application/pdf	4008	169	42	BEAM consists of three main components [5]: � VISAT, a visualization, analyzing and processing desktop application comprising func- tions for – data import and export (formats Envisat N1, CEOS, HDF, GeoTIFF, BEAM- DIMAP), Geinformatics FCE CTU 2010 38 Pot̊učková M., Štefanová E.: Utilization of BEAM and NEST open source toolboxes in education and research – displaying images including navigation window, layer manager and enhancement tools, – basic image analysis: histogram, scatter plots, band transect profile, definition of points of interest (so called PINs), spectrum view in PIN positions, geometric corrections – Generation of image products: reprojection, orthorectification, connecting images to a mosaic, band arithmetic, band filtering, – advanced processing: cluster analysis, spectral unmixing and special functions suited for processing MERIS data (SMILE and SMAC correction, radiance to reflectance processor, NDVI processor, cloud probability processor). Spectral signatures of selected vegetation species The main advantage of MERIS data in monitoring of vegetation is in their high spectral and temporal resolution.	cache/gi-2708.pdf	txt/gi-2708.txt
