Transforming Geometrically Enhanced Conceptual Model Schemas to GML

Part of the Lecture Notes in Computer Science book series (LNCS, volume 7260)

Abstract

Successful implementation of geographic applications starts with conceptual design. A conceptual schema will then be transformed into a database schema that can be implemented. Geography Markup Language (GML) has emerged as an open standard that provides a common grammar for coding geo-spatial content and exchanging over the Internet. In this paper we discuss the transformation from Geometrically enhanced ER model (GERM) to GML. GERM is an extension of the classical ER model that has been successfully used for conceptual modelling of geographic applications. The transformation rules have been chosen such that relevant application semantics is preserved during the transformation. We further present an bottom-up algorithm for transforming GERM schemas into their GML counterparts. A case study is conducted to demonstrate the effectiveness of the algorithm.
