This study presents the result of an investigation into the dynamics of urban growth and urban landscape change in the Dallas-Fort Worth area of the United States using Landsat satellite data over a 30-year period. The goal was to assess the impact of urban growth on the landscape of the area in order to provide baseline information that can support a sustainable urban growth in the future. To achieve this goal, Landsat satellite data were classified on a broad scale for four epochs (1988, 1998, 2008 and 2018) and a change detection of the landscape of the area was conducted using the four datasets. To understand the dynamics of the spatial pattern of the change that is taking place in the area, landscape metrics were incorporated into the analysis. The result showed that over the 30-year period understudied, built-up lands increased as expected. However, the result also showed that the major type of growth witnessed in the area was infill, which is considered an excellent approach to urban development as it minimizes sprawl. Additionally, results from incorporating spatial metrics into the analysis showed a stable entropy value for the study area at the metropolitan scale. However, at the County level, both Collin and Denton Counties experienced increased entropy values, indicating sprawling, while Dallas and Tarrant Counties experienced decreased entropy values, indicating infills. These results provided baseline data that can be incorporated into future urban growth plans for the area.
