• Spatial structure
  6 August 2004, by B. E., Th. St.-J.

  The word "structure" comes from Latin struere which means to build, to arrange, and contains the notion of an organised thing. Spatial structures exist, because geographical space is not constituted by a set of unique places, occupying random locations. The successive choices of actors and, more broadly, the answers given by societies to the issue of space control , obey to certain logics, even if the overlapping and interweaving of these logics make their legibility more or less evident; (...)

• Spatiality
  6 August 2004, by D. P.

  Spatiality combines all conditions and practices of individual and social life that are linked to relative position of individuals and groups with regard to one another. One fundamental postulate of geography is that those relative positions (or geographical situations) determine, probably or partly, form and intensity of social interactions. These in turn build back, while distorting them in an incremental way, the main structures of geographical space. Spatiality is one of the two main (...)

• 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 (...)

• Situation
  13 October 2004, by B. E.

  In common language, situation of an object on the Earth surface is the same as its position. In everyday use, both terms: situation and position, are used indiscriminately. They refer to reference points conventionally designated by means of an explicit reference system, namely geographical coordinates (latitude, longitude).
  In geographical discourse, situation defines a relative location in space. For a given place, it is expressed with respect to that of other places whose physical or (...)

• Distance
  6 October 2004, by D. P.

  Interval to cover in order to go from one place to another, distance has a meaning of separation, its covering requires effort, expense of energy. The mathematical definition of distance is restrictive: a measure of gap between objects is a distance if it is symmetrical, if it is not negative, if it is null only when two objects merge, and if it verifies triangular inequality. A space endowed with distance in the mathematical meaning is a metric space. Observed or cognitive geographical (...)

• Gradient
  6 October 2004, by D. P.

  Is called gradient the variation of intensity of a phenomenon per unit of distance between a place and a given centre (or axis). It is the case for example with density gradients which develop around a city centre, gradients of population, facilities, shops, services, gradients of land prices, etc. gradients of population which appear on either side of some traffic ways or else starting from a coast, etc. Geographical gradients are the expression of the fact that places belong to fields of (...)
