Interoperability of Conceptual Geographical Data Schemas using UML Infrastructure

چکیده
Issues in the area of geographic databases, caused by the lack of a standard geographic conceptual data model, can be classified as interoperability problems. This paper proposes a method to reach horizontal interoperability, i.e., a schema can be transformed in another schema designed using a different model. UML infrastructure and the Enterprise Architect CASE tool are used in the process. To reduce the number of transformations between all schemas, a UML Profile called GeoProfile is used as a base model. OCL expressions are used to enforce spatial constraints.

In the last 20 years, several conceptual data models specific for Geographic Information Systems (GIS) have been proposed. However, so far there isn’t a consensus model, which has generated several problems for the GIS area, such as the lack of interoperability among CASE tools that give support to these models. A UML profile, called GeoProfile, was proposed to standardize the task of geographi...
