The model of geographical space of the Earth is represented as a multilevel discrete grid structure. This provides a scientific basis for the construction of a natural geoinformation system of the globe with invariant organization of data in the form of a universal grid, i.e. a different-level set of elementary cells with discrete topology. A grid structure is a multilevel system of reference points, with respect to which a spatial analysis of the territory is carried out. Reference points have attributes reflecting the territorys hierarchic level and location characteristics. It is found that there is a connection between the topology of the cells and specific structures of the Earth, and between the lineament network and the hydrological network in particular.
