| Résumé anglais |
Since the 1970s, the urban growth of the Greater Cairo region has been analysed from remote sensing data. Using data from the first Landsat satellites, a methodological base was created, notably to ensure that the digital data met with the objectifs of the classification and the multitempo- ral analysis. The subsequent use of Spot data appears to offer new possibilities, but confirms the basic rule of the need for a detailed knowledge of the site and for continuous verification. The results obtained allow the spatial forms of urban growth in the Greater Cairo region to be clearly identified. Compared with the zones of colonisation and their spectacular forms in empty regions of the desert, urban development in the valley is more complex. Urban expansion has occured by stages, at the same time integrating the older built-up areas of agricultural villages. Growth is retained within the limits of the Greater Cairo ringroad.
