Distributed models are more and more used in regional hydrology. One of the main reasons is their essential compatibility with raster data in Geographical Information Systems. Also in urban hydraulics, distributed models are promising but their development depends on the availability of high-resolution data able to represent urban features. Public databases from satellite imaging are not yet adequate. The paper investigates the possibility of using other kinds of databases designed more specifically for cartography. The advantages and inconveniences of such an approach are pointed out, based on two actual examples.
