摘要：The technology improvements together with evolutions due to the decentralization of services and data processing developments have deeply modified most professional practicing in many fields. This variety of fields have a spatial reference and are generally dealt with through Geographical Information Systems (GIS). Recent awareness for information economic, strategic and social dimensions and the major role of related techniques have lead to an important increase, worldwide of software packages for management and processing usage of spatial referenced data. Even if the use of such tools covers a many fields, thus concerns many products as users needs, it necessitates however several primary treatments such as collecting, cleaning, structuring and updating data and if necessary discarding whatever are useless, etc.. What is particular in spatially referenced database studies is embodied in the fact that they require the implementation of several processes that may solve problems rising from the control of a huge data volume. These data are very complex to deal with because they are twofold : descriptive data (attributes) and spatial data (geometry and topology).
