Abstract |
: |
Al-Taif region is inserted in Eltharwat Mountains at the southwest of the Arabic peninsula, at an altitude of 1700 m above sea level. Such location inherits valuable resorting conditions characterizing the area. Al Taif city is a good example that may show the possibility of urban sprawl on the account of green land, as previous studies pointed out its vast expansion. However, it is necessary to define the nature of urban expansion to avoid the environmental degradation. Multi-temporal satellite images proved to be an excellent tool to detect the qualitative and quantitative changes in land features. Also, multi-resolution satellite data allow insinuating on surrounding details to predict the changes nature and risk that might be induced due to continuous changes. The objective of the article is to determine the magnitude of the urban expansion and point out its nature, on the long term, at Al-Taief area, using the multi concept of remote sensing, integrated with GIS.
A number of four LANSAT thematic and enhanced thematic mapper satellite images, dated 1984, 1990, 2000 and 2011 were used. Hybrid classification concept was followed using ENVI 4.7 software depending on spectral data, ground checkpoints and the digital topographic maps. Change detection analysis is based on a pixel-by-pixel basis. |
