A Heterogeneous Geographic Information Architecture For Hong.. - Drew, McInnis (1994) (Correct)
....(e.g. alphanumeric attribute information is stored in a relational model and spatial information is stored in a proprietary internal store) The information is reconstructed as part of the application code of the GIS itself. If instead, a richer data model such as an extended object oriented model [9, 22, 23] were provided by the data store, basic units such as buildings could be modeled and managed as unified objects that happen to be comprised of heterogeneous subcomponents (graphics, text, etc. In this case, the GIS application code currently dedicated to combining information from different ....

Managing Multiple Representations of Georeferenced Elements - Medeiros, Bellosta, Jomier (1996) (1 citation) (Correct)
....representations in geoprocessing is related to the fact that users must model and store data about the world for different types of application. This requires sampling and discretizing reality, and therefore implies several open issues, notably those involving data quality [5, 8] As remarked in [27], even though the state of a given entity may remain unchanged, its representation and relationships with other entities may vary according to user perspectives. 27] defines diversity in representations as a result from variations in users requirements. Though this is certainly true, we prefer ....
....and discretizing reality, and therefore implies several open issues, notably those involving data quality [5, 8] As remarked in [27] even though the state of a given entity may remain unchanged, its representation and relationships with other entities may vary according to user perspectives. [27] defines diversity in representations as a result from variations in users requirements. Though this is certainly true, we prefer to emphasize that different dimensions exist through which representations may evolve e.g. resolution, time, model, user point of view, and others. We analyze ....

Databases for GIS - Medeiros, Pires (1994) (6 citations) (Correct)
....in mind, and usually result from coupling an expert system to a relational dbms. Rules help users in their queries, by performing inferences on stored data. Most rule systems deal exclusively with alphanumeric data (e.g. 63] Some support processing fuzzy queries on spatial relationships (e.g. [66, 40, 68]) 9 Other Issues This paper discussed some of the issues that arise when dealing with database support for gis, given the different points of view of end users and database researchers. There are many other (open) issues in database support for gis applications. The first issue to consider is ....
