Abstract

Smart cities generate large amounts of Internet of
Things data from diverse sources, often presented in varying
formats and with inconsistent quality, complicating effective data
management and interoperability. Despite recent advancements
related to geospatial data standards and interoperability
frameworks, there is a need for modular and comprehensive
semantic frameworks that can leverage distributed architectures
to manage specific geospatial functions, such as real-time disaster
response mapping and resource allocation in smart cities. This
paper presents the MicroMaps framework designed to enhance
decision-making in smart city projects by addressing geospatial
interoperability issues in cloud-native geographical information
systems through semantic integration. MicroMaps employs
semantic models and microservices to standardise data into an
ontology-driven knowledge graph for real-time processing. This
geographical information system provides an end-to-end solution
to integrate, distribute and visualise geospatial data. A case study
at Keele University demonstrates this framework’s capability to
unify and analyse diverse datasets, including real-time sensor data
and historical time-series data on energy consumption and climate
conditions. The findings underscore the framework’s ability to
uncover spatial patterns, thereby improving spatial data
infrastructure and decision-making.
