Human activities produce imprints in space and time. In this regard, Night-light data is observed to be reflective of the geographical behaviour of economic activities and many other economic parameters as well. Further, Night-light data measured through radiance through satellites has been gaining immense consideration as a representative of multiple economic analysis. Of the data types available in this regard, Visible Infrared Imaging Radiometer Suite (VIIRS) data has been observed to be less erroneous, cutting edge and spatially more precise than any other data base. The current study is an indirect investigation of economic activities in the developing nations of Bangladesh and Sri Lanka in South Asia over the last five years, out of which two have been reeling under the effects of the life altering COVID-19 pandemic through observations of NOAA-VIIRS satellite data. Results depict a specific pattern of radiance in Bangladesh and a highly fluctuating trend of radiance for Sri Lanka spatially and temporally, indicating a specific and non-specific trend in economic activities respectively.
