Résumé partiel
The objective of this study is to map and assess the relationship between tree/green cover and carbon emission from cars in Khartoum Locality (KL) using remote sensing data and mapping in Geographical Information Systems (GIS). The main data used provided by remote sensing satellites such as Landsat and Quick Bird satellites. Digital geode database was built with many map layers such as vegetation cover and carbon emission required for spatial analysis. Specifically, a 2011 Quick Bird Satellite image of 0.5 m spatial resolution was processed and analyzed to extract the vegetation cover based on visual and digital remote sensing techniques. The study implemented remote sensing and GIS techniques to map tree / vegetation cover and other elements in KL during the period 2001-2011. The resulted maps were further used in GIS to spatially assess vegetation and Co in the area. This was done by linking vegetation density maps to carbon emission maps to detect threats of Co concentration and distribution in the study area. In order to further study, the vegetation change dynamics of KL forest cover, tree cover detection method has been applied to produce maps of tree cover based on the classification of the multi-temporal imagery .Change detection analysis had shown a significant change in tree cover/vegetation ‘’Between’’(2001-2011). However, the produce maps of KL land use / land cover (LULC) showed that decreased in tree cover in Khartoum Center and Alshagra Units, was less than that occurred in Khartoum North, Khartoum East, Khartoum West or Alshuhada and Soba Units. Moreover, the relatively high vegetation/agricultural land area analysis for Khartoum East, Khartoum North, Khartoum West, Alshuhada and Soba Units could be a result of re-habitation of tree cover involving the local orchards.
