Urban features visible - shortwave Infrared spectral reflectance measurement

1 Scope

This standard specifies the requirements for visible light - shortwave infrared reflectance measurement of urban landforms, including the measurement conditions, the basic measurement requirements, measurement Specific requirements, measurement records, measurement results processing and measurement summary. This standard applies to access to the development and utilization of non-agricultural land within the typical region in the 380nm ~ 2500nm wavelength range Within the spectral reflectance measurement.

The spectral bandwidth is usually expressed as the spectral response of the radiation measurement channel 1/2 of the peak of the curve corresponds to the wavelength interval. 3.4 Standard reference standardreferenceplate Homogeneous flat sheet. Its uniform reflectivity and satisfies the Langbian surface characteristics, reflectance with wavelength and time changes gently and changes can be determined.
