Abstract
This work deals with the development of urban growth scenarios and the prevision of the spatial distribution of built-up area and population for the urban area of the city of Guangzhou in China. Using freely-available data, including remotely sensed data as well as census data from the ground, expenditure of time and costs shall remain low. Guangzhou, one of the biggest cities within the Pearl River Delta, has faced an enormous economic and urban growth during the last three decades. Due to its economical and spatial characteristics it is a promising candidate for urban growth scenarios. The monitoring and prediction of urban growth comprises data of population and give them a spatial representation. The model, originally applied for the Indian city Ahmedabad, is used for urban growth scenarios. Therefore, transferability and confirmability of the model are evaluated. Challenges that may occur by transferring a model for urban growth from one region to another are discussed. With proposing the use of urban remote sensing and freely available data, urban planners shall be fitted with a comprehensible and simple tool to be able to contribute to the future challenge <i>Smart Growth</i>.

1.1 Economic Growth and Urban ExpansionComing from the traditional urban form of the walled city, later “influenced” by European planning approaches, replaced by principles of socialist city planning and economic decisionmaking (Wu, 2015) and transferred into the modern China, urban planning in China has encountered several changes
This work deals with the development of urban growth scenarios and the prevision of the spatial distribution of built-up area and population for the urban area of the city of Guangzhou in China
To support local governments efficiently as well as spatial planners and other professionals being involved in planning processes and to reduce costs, our approach was to work with freely accessible data from remote sensing and public census data which were provided by the Statistics Bureau of Guangzhou Municipality
Summary
1.1 Economic Growth and Urban ExpansionComing from the traditional urban form of the walled city, later “influenced” by European planning approaches, replaced by principles of socialist city planning and economic decisionmaking (Wu, 2015) and transferred into the modern China, urban planning in China has encountered several changes. Due to fast economic growth, internal migration and very active building activity urban planners in China face many challenges. With regards to demand and supply of energy resources, including their spatial distribution, city-wide energy-planning requires understanding of the complex system interdependencies at urban level (Agugiaro, 2015). Western concepts such as ‘smart growth’ or ‘new urbanism’ have been imported to China (Song and Ding, 2009; Wu, 2015). In most western and Asian countries for a long period of time energy planning was hardly part of urban planning strategies or development plans; in terms of Smart City and Smart Growth an unacceptable state
