A foolproof web service for spatial data aggregation and analysis
2023-10-05, 11:50–11:55, Poster presentation

We demonstrate a novel web service that offers comprehensive spatial context for areas of interest. The spatial context includes diverse types of information, e.g., land coverage, demographic and econometric data, weather, and air quality measurements, and more. These datasets originated from numerous official sources and services across the EU, assuring the reliability and accuracy of the information. The spatial-context (SC) service is enhanced with a map-centric UI that serves as an input and output interface. The user can simply draw an arbitrary polygon within EU boundaries to gather aggregated information, visualize data, and select variables to render clusters and outliers. The integration of various data sources and the provision of a user-friendly interface makes SC service a powerful tool for analyzing and interpreting spatial data in a comprehensive and efficient manner.
The primary aim of this service is to enrich with additional metadata the GEOSS Portal cognitive search developed in the context of the EIFFEL EU-funded project. In particular, a specific spatial dataset can give a broader perspective in the context of additional multidiscipline data. For example, the physical and social surroundings can potentially influence the interpretation of the data and can provide insights into relationships among variables and underlying trends. Realizing the potential and perspective of this venture, we propose the SC service as an autonomous open-source application, able to provide insights quickly and straightforwardly using aggregated open datasets easily obtained from reliable sources, such as the Eurostat and Copernicus.
One of the significant characteristics of the proposed SC service is the ease with which their data sources can be extended. Registered users can upload almost any spatial dataset, specifying the necessary information for data integration into the service and making the data publicly available. Beyond providing aggregated results and data visualization, the service has been enriched with some extra features. The first is Machine Learning (ML)-based geospatial clustering, with clusters formed based on the user-selected variables. Users also have the option to upload ephemeral datasets to be combined with existing ingested sources. Clustering procedure results in an interactive choropleth map with cluster visualization, including the automatic detection of spatial outliers. Another available analysis tool will be the geographically weighted regression (GWR) operating multiple local regressions on point data. Furthermore, a spatiotemporal analysis can be performed for variables with data available for multiple years. This is achieved after estimating and clustering the GWR coefficients separately for each year. The modular architecture of the SP service allows for more features to be included in the future.
