Abstract
Libyan cities have experienced a period of rapid urban expansion in the past decades. Urban growth as an example has been the focus of urban researches for a long time. Due to the complexity of the urban growth process, it’s very difficult to model urban growth using traditional urban models. Recently, urban researches are keen on a new technology, Remote Sensing. Remote Sensing technique was applied in many aspects of life, due to ability of covering and representing the real world around us. In urban research, field researches set up many applications to simulate the urban phenomena such as sprawl process, landuse change trends, landcover...etc. Remote sensing technology helps to extract and organize the data about such phenomenon. In addition to understand their spatial relationships, and provides a powerful means to planners and decision makers for analyzing and information about a place or a phenomenon. This will have great impact on the quality of the decision-making. The study uses Spot 5 images, topographic maps which derived from aerial photographs for the year 1980. The remote sensing image interpretation and change detection to review the urban expansion for the study area in (1980 and 2009).Spot satellite image of 2009 and Landuse maps1980 will be used to derive information on urban land use in the study area. The visual interpretation is used to extract landuse. The mutual use of Remote Sensing (RS) and Geographic Information System (GIS) describes the overall physics changes of the study area. This effort can be considered as an application case in this field (RS-based town planning information system), where this thesis show how that system can be useful of using this technology and supporting the sector by developing a model that can support the process of planning and maintain what remained of the agricultural lands to prevent them from encroachment by the urban growth.
