An Environment for the Conceptual Harmonisation of Geospatial Schemas and Data

We present a system for defining and evaluating conceptual schema mappings for the harmonisation of geospatial data sets. The goal of this system is to allow domain experts to ensure logically and semantically consistent mappings and consequently high-quality transformed geospatial data. Furthermore, a major focus is put on documentation of the schema transformation process and its impacts, e.g. in the form of lineage information attached to the resultant transformed data. This paper provides a summary of our mapping methodology, outlines lessons learnt in the first two evaluations and explains how the architecture we implemented evolves to meet upcoming user requirements.
