Leicester Digital Mapping
Data Interoperability
The success of the Leicester Digital Mapping project depends upon the range, accuracy and usefulness of the data it incorporates, and upon the ability of large and diverse data sets to overlay and interact with one another. This part of the project therefore focuses upon data gathering and integration, and the creation of an underlying computational infrastructure (see DARBS) that is capable of uniting the various elements.
Ontology-based data understanding approaches will be designed to achieve data interoperability in data integration part of this project. Geographical ontology will be used in data understanding and integration for following purposes:
- Metadata: Definitions for the basic atomic information in the data source – data about data.
- Global Vocabulary: Geographical thesaurus which will be used as reference for terms in all data sources.
- Data Glue: Not only stick the semantic heterogeneous graphical data together, but also adhere related data from different aspect. E.g., graphical information, historical information and cultural information
- Knowledge Based Queries: Knowledge based reasoning engine will enable precise and efficient query in integrated data sources.
