Land use change analysis in the Zhujiang Delta of China using satellite remote sensing, GIS and stochastic modelling

Rapid land use change has taken place in many coastal regions of China such as the Zhujiang Delta over the past two decades due to accelerated industrialization and urbanization. In this paper, land use change dynamics were investigated by the combined use of satellite remote sensing, geographic information systems (GIS), and stochastic modelling technologies. The results indicated that there has been a notable and uneven urban growth and a tremendous loss in cropland between 1989 and 1997. The land use change process has shown no sign of becoming stable. The study demonstrates that the integration of satellite remote sensing and GIS was an effective approach for analyzing the direction, rate, and spatial pattern of land use change. The further integration of these two technologies with Markov modelling was found to be beneficial in describing and analyzing land use change process.

A remote sensing?GIS evaluation of urban expansion and its impact on surface temperature in the Zhujiang Delta, China

The Zhujiang Delta of South China has experienced a rapid urban expansion over the past two decades due to accelerated economic growth. This paper reports an investigation into the application of the integration of remote sensing and geographic information systems (GIS) for detecting urban growth and assessing its impact on surface temperature in the region. Remotesensing techniques were used to carry out land use/cover change detection by using multitemporal Landsat Thematic Mapper data. Urban growth patterns were analysed by using aGIS-based modelling approach. The integration of remote sensing and GIS was further applied to examine the impact of urban growth on surface temperatures. The results revealed a notable and uneven urban growth in the study area. This urban development had raised surface radiant temperature by 13.01 K in the urbanized area. The integration of remote sensing and GIS was found to be effective in monitoring and analysing urban growth patterns, and in evaluating urbanization impact on surface temperature.

EVENTS: 3rd International FIG Workshop on 3D Cadastres

When :	25 Oct 2012 to 26 Oct 2012
Where :	Shenzhen -
Website :	http://www.cadastre2012.org
Description:	The aim of the Third Workshop on 3D Cadastres is to consider current developments and practices in an international context. The workshop will be organized as joint activity of Urban Planning, Land and Resources Commission of Shenzhen Municipality, Wuhan University and the International Federation of Surveyors (FIG) joint commission 3 and 7 Working Group on 3D Cadastres.

The 3^rd International FIG Workshop on 3D Cadastres will be organized in Shenzhen, China, 25-26 October 2012.
Submissions are possible via the 3D Cadastres 2012 EasyChair website

Background

A fast-economic growth with steadily rapid urbanization has brought about a challenge to limited land resource in urban areas. The challenge urges a shift of land use from land surface to land space in terms of land administration. The recently experienced development and utilization of land space in developed cities has broken through the traditional frame of parcel-based or 2D cadastre. The three dimensional (3D) cadastre is suggested and accepted by the research community of land administration as an effective means to support administration of land space technically. The possibility to register property unit in three dimensions efficiently will facilitate the dense and complex use of urban space.

The FIG joint commission 3 and 7 Working Group on 3D Cadastres was formed to meet the needs of 3D cadastres in legal aspects, technical aspects and institutional aspects. The first 3D Cadastres workshop (2001) and the second workshop (2011) were held both in Delft, the Netherlands.

The aim of the Third Workshop on 3D Cadastres is to consider current developments and practices in an international context. The workshop will be organized as joint activity of Urban Planning, Land and Resources Commission of Shenzhen Municipality, Wuhan University and the International Federation of Surveyors (FIG) joint commission 3 and 7 Working Group on 3D Cadastres.

Objectives & Scope

Multiple layers and 3D land utilities push the development of 3D cadastres, which relate tightly to land remarks, policies, regulations and policies. Every county has its own characteristics and solutions to 3D cadastres according to its legal, institutional and cultural issues. The main purpose of the symposium is to bring together about 100 participants from different parts of the world and have a fruitful exchange of ideas about current developments and practices of 3D cadastres, and discuss its key techniques and applications to support the efficient utility and management of urban geo-space. Also the latest practices in China, especially in Shenzhen, will be presented.

Topics

Topics within the special focus include, but are not limited to:

Current developments and practices of 3D cadastres Overall situations on legal, technical and institutional aspects Legal issues and policies about 3D cadastre Data collection and modeling 3D topology 3D visualization 3D planning of urban space Investigation and detecting of underground space Qualifying and registration of the real estate 3D estimate of 3D land space Prediction and Monitoring of 3D land use
