Spatiotemporal analysis of light pollution in Samsun (Turkey) using spatial statistics and algebra from SNPP/VIIRS satellite imageryOzturk, Sarp Doruk (Avtor) Ozturk, Derya (Avtor) light pollutionremote sensinggeographic information systemsspatiotemporal analysisSNPP/VIIRSurbanizationenvironmental sustainabilityThis study analyzes the spatiotemporal changes in light pollution in Samsun (Turkey) from 2012 to 2024 using remote sensing and geographic information systems. SNPP/VIIRS satellite data from five years were examined using spatial statistics and algebraic methods to measure nighttime light variations. Results show a sharp decline in dark sky areas and expansion of high light zones from 85.9 km² to 139.5 km², and medium zones from 87.6 km² to 145.5 km², driven by urbanization and industrial growth. Rapid changes occurred in Atakum, Ilkadim, Canik, and Tekkekoy, affecting sensitive ecological and astronomical sites. The strong correlation between light emissions and socio-economic indicators highlights the need for sustainable lighting policies to mitigate adverse environmental impacts.20252026-02-08 16:52:02Neznano27463UDK: 504.6:628.971.7(560Samsun)”2012/2024”, 528.8(560Samsun)”2012/2024”ISSN pri članku: 1581-6613DOI: 10.3986/AGS.14506COBISS_ID: 267265027slImetniki avtorskih pravic na prispevkih so avtorji
