Gülsüm Ecem Demirdağ
This study investigates the dynamics of Land Use and Land Cover (LULC) changes along the İzmir-Denizli Highway corridor in western Turkey from 1984 to 2025, utilizing remote sensing techniques and the Landscape Expansion Index (LEI) to analyze urban growth patterns. Employing cloud-free Landsat satellite imagery and the Random Forest classification algorithm within Google Earth Engine, the research identifies and quantifies built-up area expansion over four decades. The findings reveal a significant increase in built-up areas, particularly after 2000, with a total expansion from 45682 hectares in 1984 to 68869 hectares in 2025. The analysis highlights a predominance of edge-expansion growth (71.3%), with outlying growth (27.4%) and minimal infilling growth (1.3%). This trend indicates a sh...
