What about spectral signature of urban area?
The spectral signature of urban areas typically includes high reflectance in visible bands due to man-made materials like concrete and asphalt, low reflectance in near-infrared bands due to lack of vegetation, and often higher temperatures in thermal bands due to heat absorption and retention by buildings and roads. Additionally, urban areas may exhibit unique spectral signatures in shorter wavelengths due to specific materials or surface properties.

Why Nature of spectral reflectance curves?
Spectral reflectance measure a thin film's characteristics by reflecting light off the film and analyzing the resulting reflectance spectrum over a range of wavelengths. Light reflected from different interfaces of the film can be in- or out-of-phase so these reflections add or subtract, depending upon the wavelength of the light and the film's thickness and index. The result is intensity oscillations in the reflectance spectrum that are characteristic of the film.To determine the film's thickness, the software calculates a theoretical reflectance spectrum that matches as closely as possible to the measured spectrum. It begins with an initial guess for what the reflectance spectrum should look like, based on the nominal film stack. This includes information on the thickness and the refractive index of the different layers and the substrate that make up the sample. The theoretical reflectance spectrum is then adjusted by adjusting the film's properties until a best fit to the measured spectrum is found.This metrology can be used on thin film thickness measurement, even for transparent films.
