Abstract
The proliferation of spatial data from modern and increasingly prevalent technologies has resulted in large datasets, ripe for extracting insightful knowledge that can drive many applications. The most common datasets indexed by Google Dataset Search come from geosciences and social sciences, with 14 million datasets representing 45.2% of all indexed datasets, accessed by one-third of the users, and dominated by spatial data. This, in turn, necessitates the deployment of scalable and expressive analysis tools capable of extracting significant global insights. In this landscape, spatial statistical analysis emerges as a critical tool enabling social scientists to analyze large spatial data, while maintaining statistical significance in their results. However, an evident gap remains, as the current roster of spatial data science tools either support spatial statistical analysis but falter when handling large-scale datasets, or can manage big data but struggle to articulate spatial statistical queries effectively. Our research bridges the two worlds, exploring innovative query processing techniques that amplify both query expressiveness and scalability. Moreover, our work forms part of an expansive vision for identifying common utilities for spatial statistical analysis that merit system-level support, foreseeing a more profound integration between big data systems and spatial data science tools.t.
