SEMANTIC HETEROGENEITY OF GEODATA
Zhu Xu, Y. C. Lee · 2002
Semantic heterogeneity is a major barrier to geodata sharing. The aim of this paper is to improve understanding of semantic heterogeneity. It provides discussions on what semantic heterogeneity of geodata is, what its sources are, what semantic heterogeneity is irresolvable and how to avoid. The conclusion is semantic poverty and poor conceptual modeling are major forms of semantic heterogeneity. We also argue that spatial database generalization is a critical technique to facilitate geodata sharing.
