(a) forward planning, by the prediction and monitoring of detailed urban land 
use classes, 
(b) socio-economic differentiation of urban areas for inter-census monitoring 
using image surrogate data, 
(c) urban catchment studies by combining predicted surface data (and thus run- 
off coefficients) with rainfall and terrain data. 
Further research will be necessary, however, to capitalize on the urban advan- 
tages of high resolution data.
