This research aims to examine the spatial structure changes of internal urban land use based on the interpreted datasets of 1984 and 2008. Spatio-temporal patterns of internal land use conversion and urban expansion are analyzed, and then dominant driving factors (e.g., social economy, population growth and urban planning) were identified. The results indicate that Beijing′s intra-urban layout has experienced tremendous adjustment from compact to disperse configure, otherwise its function objects have shifted from the major economic and industrial development before the 1990s to the combination with cultural, high-technological and inhabitable city at present. The dominant urban land use transformations include the relocation of industrial lands from core districts to suburban or other provinces, and the accelerating expansion of residential areas and green spaces for supplying the demand of housing and ecological protection. Although Beijing′s urban planning has experienced three major adjustments and improvement since the 1980s, its optimization of urban internal patterns still remains a challenge.展开更多

This study examines changes in land use, socioeconomic indices, and the transportation system of Gifu City during the late 20th century using geographical information system (GIS) methods. The data for the study were historical maps and the population census and economic statistics data from 1950 to 2000, when Japan was in a period of high economic growth. The discussion focuses on the master plan, road construction, land use, the spatial distribution of the population, and socioeconomic indices. It was possible to compare spatial distribution patterns over time using GIS. When policies were created that attached importance to construction of a road network due to the development of motorization and elimination of the city tram, the surrounding suburban area became the focus of land-use development. As a result, Gifu City is plagued by the doughnut phenomenon. It is important to identify the relationships among urban planning factors to provide for future urban and transportation planning.展开更多

The system features that it has expendability,maintainability and universality, makes data be shared between different components of DSSUERand provides help facilities and protection. The system is built by using database and graphic basetechnologies it consists of the main control module, data-management module and data-proassingniodule. The applications of this system is demonstrated by an example which is the case ofsuitability analysis of land use for residential areas in Tianjin.展开更多

Their role in sustainability and development planning is thus unique and es- sential. National cartographic centers and national mapping agencies offers example of such national mapping agencies. Accurate information on land and environmental resources is essential to effective land use planning. Key sources of in- formation include topographic maps, aerial photos, satellite images, and data derived from geographic information sys- tems (GIS). At the national level, this information can be used to identify environmental resources, reveal the develop- ment potential of the country, and help promote effective ecological studies and sound land use planning with a land use planning approach. This article begins with some general comments on the importance of land use planning, and outli- nes some current environmental issues and also highlights the connection between roles of Geo-referenced information in land use planning with a sustainable development approach. The discussion describes several key methods of resour- ce identification, with particular emphasis on aerial photography and the existing potentials of Iran in this field. The ar- ticle also discusses the role that the Geo-referenced information and environmental planning play in developing and promoting geographic information system use to sustainable development and finally present proper models to use en- vironmental information and geo-referenced data for sustainable development.展开更多

Special analysis also attention was paid to population density for the construction of the land development priority map and using satellite image analysis to determine land use changes and analysis of geo-spatial information, because highly dense populated areas represent the highly important urban and industrial areas. While geo-information technology offers an opportunity to support flood management adequate geo-spatial information is a prerequisite for sustainable development, but many parts of the world lack adequate information on environmental resources. Such information providing, which serves as an important tool for decision-making in land use planning, can help provide effective information to natural disaster management. This paper develops a framework for flood control and begins with some general comments on the importance of land use planning and outlines some current environmental issues and then presenting environmental models to use in disaster management plan by using GIS and remote sensing results. Flood control is a complex problem that requires cooperation of many scientists in different fields. The article also discusses the role that geo-information and environmental planning and GIS and remote sensing technology play in disaster management control to reduce negative impacts of flood and present proper alternatives for developing of Gorganrood in the north of Iran. Advanced high-resolution sensor technology has provided immense scope to the decision makers for analysis of flood and damages details using GIS and remote sensing.展开更多
