Human-Computer Interface (language / model)
The definition of a visual query language for Geographical Information System was one of the first studied subjects. A query language, CIGALES, allows defining a query on a database with geolocalizaed data. Visual, since the main concept is the representation of a set of desired spatial relationships defined by the end-user with a drawing (illustration as QBE did for alphanumeric data but applied to (geo-)graphical components). CIGALES is a declarative language in the sense that it does not define any order for the actions to be performed to solve the query but presents the desired spatial relationships (Mainguenaud, Portier – SDH 1990). Here are some links on publications about this subject :
- Cigales, a Visual Query Language for a Geographical Information System: the User Interface : Calcinelli – Mainguenaud – Journal of Visual Languages and Computing – Elsevier
- Classifying Ambiguities in a Visual Spatial Language : Carpentier – Mainguenaud – Geoinformatica – Kluwer
At the data model level, research directions are based on the management of multi-users applications to manage for example over-constraint problems or end-users with an heterogeneous knowledge in computer-science or in buisiness logic. Here are some links on publications about this subject :
- A framework to model and manipulate constraints for over-constrained geographic applications : Jaziri – Mainguenaud, GeoInformatica, Springer

Network management
Another research area is the modeling of network using the concept of graph. The aim is to study this modeling from the semantical point of view (the cartographical representation is not taken into account). The basic principle is to provide the representation of a network starting from the user’s level toward the cartographical level (which may not exists). Here are some links on publications about this subject :
- The Modelling of the Geographical Information System Network Component : Mainguenaud – International Journal of Geographical Information Systems, Taylor and Francis
- A data-model to deal with multiple scaled networks : Mainguenaud – Simatic – Computers, Environment and Urban Systems – Elsevier
- Constraint-based Queries in a Geographical Database for Network Facilities : Mainguenaud – Computers, Environment and Urban Systems – Elsevier
Data models
This research area is mainly oriented towards the result of a spatial operator from the semantical point of view : Which is the data model associated with the result of a spatial data manipulation operator ?). Here are some links on publications about this subject :
- Consistency of spatial database query results : Mainguenaud – Computers, Environment and Urban Systems – Elsevier
- A Revisited Database Projection Operator for Network Facilities in a GIS : Claramunt, Mainguenaud – Informatica, Slovenia
