Abstract : Geographic content production and maintenance is often done through a combination of various contributions. Thus, updating IGN geographic data relies on integrating data from partners or by involving field change alerts. This is also the case of free content produced by community projects such as OpenStreetMap. An important problem is quality management of collaboratively produced geographic content, in particular consistency management. This allows for decision-making which is based on this content. Data consistency depends on how homogenous space representation is. Likewise, it depends on preserving important non-explicit information that can be found on the geometries of the entities described in the content. This Thesis proposes a model baptized Coalla for collaborative editing of geographic content with consistency management. The model has three contributions: 1) identifying and defining elements that should be included in a formal vocabulary to facilitate the construction of collaborative geographic content, 2) user assistance process to help users build on the fly a formal vocabulary extracted from formal IGN databases specifications and existing collaborative vocabularies, and 3) a strategy for evaluating and reconciling user contributions in order to coherently integrate them into the content. Our model Coalla has been implemented in a prototype
