Raster interval object approximations for spatial intersection joins - The VLDB Journal Spatial join processing techniques that identify intersections between complex geometries (e.g., polygons) commonly follow a two-step filter-and-refine pipeline. The filter step evaluates the query pr...

🎉First paper of 2025! Great collaboration with Thanasis Georgiadis & Prof. Nikos Mamoulis.

🚀 We propose a new raster intervals approximation—lightweight, effective & tunable—delivering 3x speedup in spatial joins!
