Development of an interface for ontology‐based transformation between features of different types
Dissertation submitted in partial fulfilment of the requirements for the Degree of Master of Science in Geospatial TechnologiesImplementation of the INSPIRE directive, the spatial data infrastructure for the Europe, has created a
necessity for easy and convenient conversion between different models of geospatial data. Data
model transformation across heterogeneous systems can be hampered by differences in terminology
and conceptualization, particularly when multiple communities are involved. Requirement in current
situation is an interface facilitating transformation of data to a desired format and immediate use of
the data, which are collected from different formats and models. Ontology-aware software with
shared understanding of concepts, enable users to interact with geospatial data models. Thus use of
ontologies could make a friendly environment to the user in translating the data conveniently.
Feature type ontologies, along with annotations are provided from an ongoing project at the Institute
for Geoinformatics (IfGI, University of Münster, Germany), in order to reconcile differences in
semantics. FME workbench provides a successful environment to execute set of rules for the data
model transformation using a mapping file, which can be developed externally. The thesis work
developed a user interface that includes operations to define rules for the translation of geospatial
data, from one model to another. Annotated feature types are taken as input, and the results are
encoded as FME Mapping files. The overall methodology involves three phases.(...
