Cairo is a huge city with many problems. The most severe of these are rapid urbanisation and a totally overloaded traffic system. In many cases, satellite image interpretation is a relatively cheap and fast method of assessing these problems. The images give a complete overview of the structure of the city, allow surface classifications (e.g. urban, non-urban) and measurements (e.g. distances) and show changes in the city's development. They act as a basis for planning and as control elements.

All the following exercises are based on high resolution Landsat 7 ETM+ images. The datasets provide 8 channels, which are shown in greyscale and look quite similar. But a lot of differences can be seen when combining 2, 3 or more images. Explore the city's structures and provide information on historical, cultural and tourist sites.
