<![CDATA[This study analyzes economic development and spatial inequality in the Special Region of Yogyakarta during 2014–2024 using multi-source geospatial data, including Nighttime Light Intensity (NTL), Normalized Difference Vegetation Index (NDVI), and population statistics. Trend analysis, economic center of gravity, urban sprawl assessment, and the Gini coefficient were applied to evaluate regional development. Results show that economic activity increasingly expands outward from the urban core while vegetation remains stable. This finding indicates the phenomenon of urban sprawl, the gradual expansion of economic activity and the growth of built-up areas into the city's periphery. The NTL/NDVI ratio identifies the highest urbanization pressure in central Yogyakarta. These findings highlight the potential of geospatial indicators to complement official statistics for monitoring inequality and supporting sustainable spatial planning.]]>
