Satellite-based measurements of the artificial nighttime light brightness (NTL) have been extensively used for studying urbanization and socioeconomic dynamics in a temporally consistent and spatially explicit manner. The increasing availability of geo-located big data detailing human population dynamics provides a good opportunity to explore the association between anthropogenic nocturnal luminosity and corresponding human activities, especially at fine time/space scales. In this study, we used Visible Infrared Imaging Radiometer Suite (VIIRS) day/night band (DNB)–derived nighttime light images and the gridded number of location requests (NLR) from China’s largest social media platform to investigate the quantitative relationship between nighttime light radiances and human population dynamics across China at four levels: the provincial, city, county, and pixel levels. Our results show that the linear relationship between the NTL and NLR might vary with the observation level and magnitude. The dispersion between the two variables likely increases with the observation scale, especially at the pixel level. The effect of spatial autocorrelation and other socioeconomic factors on the relationship should be taken into account for nighttime light-based measurements of human activities. Furthermore, the bivariate relationship between the NTL and NLR was employed to generate a partition of human settlements based on the combined features of nighttime lights and human population dynamics. Cross-regional comparisons of the partitioned results indicate a diverse co-distribution of the NTL and NLR across various types of human settlements, which could be related to the city size/form and urbanization level. Our findings may provide new insights into the multi-level responses of nighttime light signals to human activity and the potential application of nighttime light data in association with geo-located big data for investigating the spatial patterns of human settlement.

As a method of cultural production and communication, remix has permeated the way the social space is perceived, conceived of and lived. Physical social space is captured, constructed and mediated with digital tools and by a multitude of users. The explosive use of cultural software and social media is actively shaping the experience of architectural and urban space. Smart city movement proponents advocate for a kind of participatory decision-making in cities that is akin to digital social space dynamics. Within the architectural practice, the space is first produced as a digital remix. The social space, both online or offline, physical or digital, crowdsourced or expert-designed, is socially produced as a collective assemblage of the fragments of digital images.  This essay aims to outline four trajectories by which physical (architectural and urban) social space is intertwined and remixed with digital (social media and the web) social space, and the broader implications of such cross-hatchings. Additionally, this paper aims to bring this term to architectural and urban discourse. Positing that remix has become the dominant model of spatial production in the contemporary world, what are the implications of it for the social space and for the public?
