摘要：
The night light images obtained by the visible light imaging linear scanning business system (e.g., DMSP/OLS) and the visible light near infrared imaging radiometer (e.g., NPP/VIIRS) carried by the national polar orbit satellite are the main data sources for monitoring the social and economic activities and natural phenomena (e.g., forest fire, oil, and gas combustion). However, the existing nighttime lighting data lack the radiation of calibration, the pixel saturation, the discontinuous time scale, and the inconsistency of the multisource night light radiance. Thus, this work proposes a method of extracting invariant target area based on linear fitting and performs the mutual correction between two kinds of data between DMSP/OLS and NPP/VIIRS images by taking the Kashi of China and Pakistan Economic Corridor as the research area. Subsequently, the correction results of the economic corridor of China and Pakistan are tested on different spatial scales, including the total amount of regional gray scale, the standard difference index, and the total of standardized difference index. Results show that the goodness of fit of two calibration models is above 0.78. The correlation between the total gray level of the corrected DMSP/OLS image and the GDP and population data significantly increased (GDP:R2=0.7689; population: R2=0.9033), and the standard difference index significantly decreased after being calibrated. The calibrated NPP/VIIRS images are more consistent with DMSP/OLS in temporal and spatial distribution, and the spatial details are more prominent. This phenomenon enhances the consistency of multisource nighttime light images and is more suitable for the analysis of long-term development trends in socio-economic factors. © 2020, Science Press.
