“…Diese Annahmen wurden zwar widerlegt, der Transfer der Methoden der Botanik und Geschichte auf die Geographie gibt aber einen Eindruck von der Bereitschaft Gradmanns, auch außerhalb der Logiken des eigenen Faches zu forschen. Diese pragmatische Anwendung 10 Christallers Arbeit wurde in den 1940ern in den USA von einer Reihe von Geographen aufgegriffen (Ullman, 1941;Bunge, 1962;Berry, 1965). Vielfach wurde sie als grundlegend für die "Quantitative Revolution" der Geographie betrachtet, was sich beispielsweise in der Widmung in Bunges "Theoretical Geography" "To Walter Christaller" (Bunge, 1962) zeigt.…”

“…Tatsächlich vergingen nach dem ersten Wiederaufgreifen der Arbeit in den USA (Ullman, 1941) mehr als 20 Jahre bis auch in Erlangen inhaltlich an die theoretischen Überlegungen angeknüpft wurde und erst zu einem Zeitpunkt zu dem Harvey in den USA schon die Überwindung der "Quantitativen Geographie" (Harvey, 1973:128) …”

Abstract. This article aims at expanding the predominant narrative of a Quantitative Revolution in German-speaking geography, to develop a more complex and multifaceted perspective on this chapter of the discipline's history. For this purpose, I take a closer look at the institute of geography in Erlangen. Eugen Wirth, the long-term chair holder in Erlangen, argued that here, in contrast to the majority of other institutes, the implementation of quantitative methods started in 1932, when Walter Christaller submitted his thesis: Central Places in Southern Germany. According to Wirth a dissertation supervised by him in 1969 was a further step towards the use of quantitative methods. I argue that Wirth made a significant contribution to the debate on quantitative theoretical geography in Germany with his textbook Theoretical Geography published in 1979, although the book was subsequently criticised and strongly rejected by Bartels and others as a conservative embrace. By examining this local negotiation process, I develop one of many narratives, that stand opposed to a unified account with which the general assembly of geographers in 1969 and Bartels' Geographie des Menschen uniquely motivated the abandonment of the concept of Länderkunde.

“…The earliest concepts of urban growth proposed that urban growth is the consequence of two factors, the distance to the city centre and the transport cost (Alonso, 1960;Ullman, 1941). The selection of factors affecting urban growth and the concept of urban systems has evolved since then, largely because urban studies have attracted researchers from various disciplines other than the geographer (Ullman, 1941). Factors affecting urban growth, hereafter called urban driving factors or factors, have been implemented to explain the urban system, and for projecting possible urban growth by implementing these factors in a model to bring insight on the location, distribution, and size of a new urban area.…”

Abstract:Urban growth modelling has attracted considerable attention over the past two decades. This article reviews the driving factors that have been identified and studied in cellular automata (CA); one of the popular methods in urban growth modelling. Over a hundred articles published between 1993 and 2012 were selected and reviewed. We extracted the driving factors from CA transition rules and arranged them in a list. The list contributes to early spatial research for the selection of factors in CA models. Our analyses show that studies between 1993 and 2000 mainly focused on using earth's physical factors in predicting urban growths, while recent studies combined them with socioeconomic factors, resulting with models with a greater number of inputs. Nevertheless, the human-behaviour factors impacting urban growth were generally under-represented. Geographically, more applications of the CA urban growth models have been seen in the developed countries compared with those in the developing countries, suggesting substantial work is needed to address issues in understanding and modelling rapid urban growth processes in developing countries.
