This study aims at determining the spatiotemporal change in urban areas by using multi-temporal satellite images with geographic information systems integration. In this study, the city of Erzincan was selected as the sample case. The analyses of change were conducted by using the optical satellite images from LANSAT TM dated 1987 and the LANDSAT ETM+ dated 2006, besides the night images from 1998, 2006 and 2010. Spatial change maps were created for the qualitative analysis, and change matrixes were formed for the quantitative assessment of these changes. The outcomes of these change analyses were then evaluated and interpreted in the light of the demographics of the population living in the area. The results obtained from the Landsat satellite images indicate that the area of the city expanded at the annual average rate of 1.65% in 1987-2006. Night images indicate that the city area grew at an annual average rate of 4.04% in 1998-2006, while this rate was 20.28% in the period of 2006-2010. The results of the study demonstrate that the usability and contribution of satellite images is quite significant in tracking and monitoring temporal and spatial change in the area.
