Operation of measure(ment) consists in attributing values to phenomena of interest in the frame of geographical questioning. On the one hand, it is used to characterise attributes of studied objects, and in these cases comes before any processing. On the other hand , it plays a role downstream, to characterise spatial forms, to describe nature and intensity of relations, to qualify similarities, etc. In the first case, measure is apprehended in the phase of acquisition of information and (...)

Theories of spatial analysis
12 January 2005, by D. P.The general theoretical position of spatial analysis consists in proposing a partial explanation as well as prediction possibilities about the state and probable evolution of geographical objects / entities, on basis of knowledge of their situation with respect to other geographical objects.
There exists not yet any general theory of geographical space that could be a theory of concentrations, of spacing, of spatial structures and of evolution of spatial systems, relying on knowledge of (...)

Fractal
6 October 2004, by D. P.(term proposed by B. Mandelbrot)
In mathematics, a fractal is a geometrical object such that the same properties are showing at different scales. There is thus a hierarchically organised structure, which follows a welldefined hyperbolic law, either determinist (regular fractal) or stochastic (random fractal):
n(e) = e D
where e is the measure interval(variable parameter characterising the scale of observation) and n the number of elements appearing at that scale. D is the fractal (...)
