A Framework Uniting Ontology-Based Geodata Integration and Geovisual Analytics

Linfang Ding, Guohui Xiao, Diego Calvanese, Liqiu Meng
2020 ISPRS International Journal of Geo-Information  
Our framework consists of two modules centered around an ontology: (1) an ontology-based data integration (OBDI) module, in which mappings specify the relationship between the underlying data and a domain  ...  To address this challenge we rely on two well-established research areas: data integration and geovisual analytics, and propose to adopt an ontology-based approach to decouple the challenges of data access  ...  In particular, it has been used for consistency assessment of open geodata [36] , and for maritime security [37] . In this work, we rely on OBDI for geodata integration.  ...

Integrating linked open data in mobile augmented reality applications - a case study

Silviu Vert, Radu Vasiu
2015 TEM Journal  
In this paper we develop a model and implement a prototype that integrates user-generated linked open data and open government data in a mobile augmented reality tourism application that works in the browser  ...  However, this integration is not straightforward and developers have to deal with known linked data integration issues and issues due to its open world assumption, such as geodata integration, data quality  ...  This step consists of analysing the information and deciding on ontology to be used in modelling that information.  ...

An Integrated GIS-Expert System Framework for Live Hazard Monitoring and Detection

James McCarthy, Phil Graniero, Steven Rozic
2008 Sensors  
For decision makers to make use of sensor web data these issues must be dealt with to some degree.  ...  This model can be understood by analysis software that leverages rule-based logic and inference techniques to reason with, and draw conclusions about, spatial data.  ...  Moving from raw sensor data to an ontological representation, which can enable an inferencing system like REASON to assess meaning and therefore relevance, can be a complex process.  ...

Highway Alignment Optimization: An Integrated BIM and GIS Approach

Linlin Zhao, Zhansheng Liu, Jasper Mbachu
2019 ISPRS International Journal of Geo-Information  
This study proposes an approach for managing highway alignment in the context of a larger landscape that integrates building information modelling (BIM) and geographic information system (GIS) capabilities  ...  To support this integration, semantic web technologies are used to integrate data on a semantic level. Moreover, the approach also uses genetic algorithms (GAs) for optimizing highway alignments.  ...  Acknowledgments: The authors would like to thank the Beijing University of Technology for its support through the research project.  ...
