"Live Maps" is the GIS platform where we offer access to georectified maps, but also where we combine various elements of data to produce maps "on the fly". Apart from producing maps based on pre-selected data, "Live Maps" includes other features. The first one is a timeline. Only the items selected for a given period will show on the maps (e.g. "schools" in 1910-1925). Each physical element like buildings, parks, etc. -- whenever this is known -- is determined by a "date of construction" and "date of destruction" (or change of function). The second feature is the link between these physical elements and the photographic database. All such identified elements in the photographic database will appear with all their associated pictures and actual location on any georectified map in Virtual Shanghai.

Luciano Cessari, Elena Gigliarelli In: Progress in Cultural Heritage Preservation Lecture Notes in Computer Science Volume 7616, 2012, pp 369-377 Abstract Climate change have impacts on many sectors: land use, housing, transportation, public health, water supply and sanitation, solid waste, food security, and energy. This article presents the results of the project SECHURBA, financed by European funds, whose purpose was to examine the potential of environmental protection and sustainability in historic cities, documenting barriers and prospects of various historical communities with diversity in Europe. Critical objectives which were achieved, such as 'Historic Community Climate Change Strategies', assessment tools, route maps to intervene in areas such culturally sensitive, are under implementation in historic urban areas in Popular Republic of China. Through the application to some typical towns and villages in the Chinese province of Zeijang the outcomes of SECHURBA will developed to outline a set of actions and tools that will call 'Historic Cities Regeneration by Climate Change Strategies'.

DOI : http://dx.doi.org.gate3.inist.fr/10.1016/j.apgeog.2011.11.006 [ScienceDirect, via Biblio-SHS] Auteur : Kai-ya Wu, Hao Zhang Paru dans : Applied Geography, Volume 34, May 2012, Pages 137-145 Abstract In this study, Hangzhou, the capital city of Zhejiang Province in eastern China was selected as a case study. Based on time series Landsat MSS/TM/ETM + imagery and historical census data, analysis of the relationship between land use dynamics, built-up land expansion patterns, and underlying driving forces from 1978 to 2008 was performed, using an integrated approach of remote sensing (RS) and geographic information system (GIS) techniques and statistical methods. The results showed that rapid expansion of built-up land in the Hangzhou Metropolitan Area (HMA) led to accelerated land use conversion. The built-up land increased from 319.3 km2 in 1978 to 862.5 km2 in 2008. Expansion patterns of built-up land in the HMA were essentially characterized by axial expansion centered on the former city proper before 1991. In 1996 and 2001, two significant administrative division adjustments for the former city proper and two neighboring municipalities occurred. This led to the success in implementing strategies of "frog-leaping development along the Qiantang River" and "crossing the Qiantang River and developing southward". Spatially, a closer linkage between the former city proper and two neighboring municipalities was established. Consequently, rapid development of infrastructures, facilities, intensive industrial parks, and urban and rural settlements along the Qiantang River resulted in the eastward and southward expansion of built-up land. Thus, from 1991 to 2008 the model of urban expansion resulted in a multi-nuclei pattern. Furthermore, as shown with detailed analysis, the growth pattern of built-up land of the HMA is highly correlated with socio-economic factors, including the gross domestic product (GDP), per capita disposable income, popul

We mapped urban land from satellite images by using a hybrid approach of spectral mixture analysis, unsupervised classification, and expert rules. We employed binary logistic regression to model the probability of urban land conversion as a function of spatial independent variables. In recent years Hangzhou started its transformation from a compact, monocentric city to a polycentric city. We found that accessibility to the central business district, industrial centers, roads, Qiantang River, the amount of built-up area in the neighborhood, locations of markets, and spatial policies were the major determinants of Hangzhou's urban land conversion. Moreover, the availability of land in the neighborhood has become increasingly important in recent years. We identified several major institutional forces underlying Hangzhou's urban development: administrative annexation and development zones, the increasingly important role of the market, and the unique role of local government. The results from our research indicate the need for policies and plans that can better manage and reduce urban sprawl in Hangzhou. [ABSTRACT FROM AUTHOR]
