Multispectral remote sensing is defined as the collection of reflected, emitted, or backscattered energy from an object or area of interest in multiple bands of the electromagnetic spectrum.
By means of the combination of spatial and temporal resolution features, multispectral sensors give a relevant contribution to Cultural Heritage monitoring by providing meteo-climatic and air quality measurements for the characterization of local scale meteorological conditions and climate change effects that have a potential impact on the conservation of historical and archaeological structures.
This described system collects 28 semi-monochromatic, i.e. high resolution images (5MPixel) one for each selected transmission band. The maximum dimension of the final 3D spectral cube is 2560*2048*28 data points. The dynamic range of the system is set to be 8 bit for each data point.
