Abstract :	[en] Many phenomena, especially physical ones are by nature continuous. Others, although discrete, can be transformed in statistical surfaces by means of potential functions. The construct generated in this way from land cover maps allow the quantitative, qualitative and geographic study of the phenomenon. It is advantageous to consider these statistical surfaces as geographical models. This is particularly true of urban potential surface. The potential fields are new generalised bands and can be utilised for realisation of color composite images called “colorama”. Further the potential fields allow to form a synthetic image which can by submitted to an automatic classification. The result is a chloropleth map of ecological landscape units.
