Introduction
I am a postdoc fellow in a joint UK-Israeli program. I study artificial light-at-night (ALAN) as a proxy for a human presence on the Earth. Currently, I am exploring the possibilities of advanced machine learning tools to extract more spectral information from panchromatic ALAN imagery.

Artificial lights raise night sky luminance, creating the most visible effect of light pollution-artificial skyglow. Despite the increasing interest among scientists in fields such as ecology, astronomy, health care, and land-use planning, light pollution lacks a current quantification of its magnitude on a global scale. To overcome this, we presen...

Research and educational activities (R&EAs) are major forces behind modern economic growth. However, data on geographic location of such activities are often poorly reported. According to our research hypothesis, intensities and spectral properties of artificial light-at-night (ALAN) can be used for remote identification of R&EAs, due to their uniq...

Mapping geographic concentrations of quaternary industries (QIs) may help to assess regional performance and formulate informed development policies. However, fine resolution data on QIs concentrations are sparsely reported. Thus, for the year 2010, only 45% of all NUTS3 regions (i.e. regions of the third and most detailed level of the Nomenclature...

Enterprises organized in clusters are often efficient in stimulating urban development, productivity and profit outflows. Identifying the clusters of economic activities thus becomes an important step in devising regional development policies, aimed at the formation of clusters of economic activities in geographic areas in which this objective is d...
Article
Full-text available
Data on geographical concentrations of economic activities, such as manufacturing, construction, wholesale and retail trade, financial services, etc., are important for identifying clusters of economic activities (EAs) and concentrations of forces behind them. However, such data are essentially sparse due to limited reporting by individual countrie...

Questionnaires are among the most basic and widespread tools to assess the mental health of a population in epidemiological and public health studies. Their most obvious advantage (firsthand self-report) is also the source of their main problems: the raw data requires interpretation, and are a snapshot of the specific sample’s status at a given tim...

Unlabelled: The physical structure of cities is the result of self-organization processes in which profit-maximizing developers are key players. The recent Covid-19 pandemic was a natural experiment by means of which it is possible to gain insights into shifts in the spatial structure of cities by studying developers' behavior. Behavioral changes...

Using satellite nighttime light (NTL) data as a proxy to measure socio-economic activity in normal times has been well-established in the remote sensing literature. In the recent years, the NTL composites produced by the Visible Infrared Imaging Radiometer Suite (VIIRS) revealed a dimming of light in major cities during the COVID pandemic in large...
Article
Full-text available
Night-time light (NTL) data have been widely used as a remote proxy for the economic performance of regions. The use of these data is more advantageous than the traditional census approach is due to its timeliness, low cost, and comparability between regions and countries. Several recent studies have explored monthly NTL composites produced by the...

The efficient modeling of population-density and urban-extent dynamics is a precondition for monitoring urban sprawl and managing the accompanying conflicts. Currently, one of the most promising approaches in this field is cellular automata—spatial models allowing one to anticipate the behavior of unit areas (e.g., evolution or degradation) in resp...

Article
Full-text available
Data on artificial night-time light (NTL), emitted from the areas, and captured by satellites, are available at a global scale in panchromatic format. In the meantime, data on spectral properties of NTL give more information for further analysis. Such data, however, are available locally or on a commercial basis only. In our recent work, we examine...
Article

Artificial night-time light (NTL), emitted by various on-ground human activities, has become intensive in many regions worldwide. Its adverse effects on human and ecosystem health crucially depend on the light spectrum, making the remote discrimination between different lamp types a highly important task. However, such studies remain extremely limi...

A functional urban area (FUA) is a geographic entity that consists of a densely inhabited city and a less densely populated commuting zone, both highly integrated through labor markets. The delineation of FUAs is important for comparative urban studies and it is commonly performed using census data and data on commuting flows. However, at the natio...

Question
I am trying to compare original and restored rgb images via ssim.
As an output, I get three ssim maps, and none of them does not coincide with the maps produced if I run ssim separately on red, green or blue bands.
I wonder, what is the calculation procedure of ssim for rgb? Please advise me.
