Abstract:
Civil infrastructural safety is a key indicator for a sustainable built environment. Urban ground subsidence and infrastructural deformation are threatening infrastructural health and human well-being, in particular, in those rapidly urbanized regions in China and other Asian developing countries. Today, advances in satellite and terrestrial sensor technologies are enabling the creation of an integrated satellite–terrestrial sensor network for regular 'Urban Computed Tomography Diagnosis' and early warning of potential deformation disasters. This paper reviews the key earth observation and terrestrial sensor technologies for urban infrastructural health diagnosis, and proposes the potentials and prospects for future development of the satellite–terrestrial system.This paper summarizes the characteristics of China's civil satellite payloads and the research status of radiometric calibration,and ascertains the calibration method flow that suits China's civil satellite payloads.We perform the calibration and validation of civil satellite by using above mentioned methods.The retrieval algorithm of land surface property parameters,such as reflectance and temperature,are researched based on the civil satellite remote sensing data.At last,a application demonstration of land surface products is performed.The result shows that the method stipulated in the paper is appropriate to in-orbit calibration and validation of satellite payloads,and the calibration coefficients are accurate for quantitative application,the demonstration result based on our country remote sensing data is very well.

The present paper describes a UV-VIS spectroradiometer named GASCOD/A4r developed at ISAC-CNR for remote sensing measurements aboard stratospheric M55-Geophysica aircraft, flying up to 21 km. Obtained experimental data are used for retrieving of NO2, O3 and of other minor gases atmospheric content, applying the DOAS (Differential Optical Absorption Spectroscopy) method. UV actinic flux and J(NO2) are also derived. All these parameters are used for satellite data validation tasks. The specific results obtained during dedicated aircraft missions in different geographical areas have already been utilized for ENVISAT validation.
