This paper discusses the spatial trends of urban physical growth of several cities in Java. Six cities in Java (Jakarta, Bandung, Semarang, Yogyakarta, Surabaya, and Malang) were chosen as samples to represent the characteristics of cities in Java using geographic settings consideration, including topography, city size, population density, and history of cities development. The objectives of this study are: (1) to understand the variations in physical growth of cities in Java; and (2) explain the spatial trends of urban physical growth of these cities based on their geographical settings. Multi-temporal Landsat satellite images were chosen as data sources to identify urban morphological development processes. Based on results of analysis, it is known that the physical growth of cities in Java has quite diverse variations in the aspect of urban settlements, infrastructure, and urban functions. However, the diversity of urban physical growth can be simplified into 4 types based on the dominant form of physical development. The four types are (1) compact-rounded city that is formed by densification process domination; (2) the spread-elongated city formed by the dominance of extensification process; (3) compact fan-shaped city that is formed by natural physical conditions; and (4) scattered-random city formed by leapfrogging process domination.
