The Adaptation of CROTIS Data Model and Generation of GML Application Schema

Zvonko Biljecki, Aida Osmanagić, Daniel Vencler

Abstract


Through the project Production of an object-oriented conceptual data model and production of GML application schema, the CROTIS data model is fully conformed to the latest ISO and OGC standards. A new data model, a new schema for data exchange and a new data catalogue have been encompassed within the project. The main elements of the project are presented in this article. The modelling was done for the purpose of data model improvement, according to standards that provide the methods and properties for display of model objects and model attributes. UML (Unified Modelling Language) is used for formal description of the data. A logical data model in UML enables the implementation of GIS, including the database as well. The automatic generation of a GML application schema was developed from UML. Data description is contained in the data catalogue, which resulted automatically from data model.
