GIS and Networks: Business Anomalies and Topological Errors, Linear Elements Case

The quality control of geographic data, especially from a topological and semantic perspective, is a must for its good management and use. However, while updating spatial data, some sorts of ano-malies are affecting it, due to negligence or non-respect of business and topological rules. Hence the necessity of a solution that enables detecting theses anomalies. Nowadays, Geographic Infor-mation Systems (GIS) have become essential for decision-making in any project that manages spa-tial data. GIS functionalities and tools give the possibility of defining the topology of vector data. Nevertheless, the topology alone does not respond to the needs in matter of defining specific rules for every facility network. This means, we could find topological errors in the spatial database, but taking into account business rules, they are correct and vice versa. The main objective of this ar-ticle is firstly to define business rules for the linear elements of a network. Secondly to premedi-tate the algorithms that detect the violation of the defined rules in order to have a good quality control of geographic data
