actually be an object 100,000cm (1km) long on the ground. Spectral angle mapper (SAM) approaches match the pixel spectra to reference spectra to classify the pixels by calculating the angle between the spectra which are treated as n-dimensional vectors in space .

The user also sets the bounds for how similar other pixels must be to group them together. Material Classes and Colors. The PowerPoint PPT presentation: "Spectral Angle Mapping and Linear Spectral Unmixing of the ASTER data for alteration mapping at Sarduiyeh area, SE Kerman, Iran" is the property of its rightful owner. many studies have indicated that thereexists a trade- off between the spatial resolution improvement and the spectral propertypreservation of the LRMI, and it is difficult for the existing methods . PowerPoint Presentation Last modified by: gislab Company: The Spectral Correlation Mapper (SCM) method is a derivative of Pearsonian Correlation Coefficient that eliminates negative correlation and maintains the SAM characteristic of minimizing the shading effect resulting in better results. Shrubland, chaparral, grassland: Iceplant (Carpobrotus edulis), jubata grass (Cortaderia jubata), and blue gum (Eucalyptus globulus) Vandenberg Air Force Base, California PDF Using ENVI and Geographic Information Systems (GIS) If a vector is drawn from the origin through each point, the angle between any two vectors constitutes the spectral angle between those two points. The approach also shows a better performance than Spectral Angle Mapper (SAM) classification (overall RMSE of 9.2 compared with 10.7 for latter). The algorithm determines the spectral similarity between two spectra by calculating the angle between the spectra and treating them as vectors in a space with dimensionality equal to the number of bands.

We introduce the spectrum angle mapper (SAM) technique to eradicate the cosmic noise from the hyperspectral Raman dataset.
