Abstract:
Geographic Information Systems require advanced spatial look-up layers to execute multi-dimensional polygon matching and proximity searching without introducing long query latency patterns. Standard bounding-box layout methods suffer from severe performance bottlenecks as geographical database densities grow, inflating the data filtration path length significantly. This paper presents an optimized spatial index model, Balanced Cell-Split (BCS), created specifically for dense geometric record layouts. The framework divides complex topographical data vectors into dynamic, non-overlapping hierarchical cells using a localized quadrant matching formula. We benchmarked coordinate query speeds across a reference database containing 50 million geographical features under fluctuating request frequencies. The experimental results demonstrate a 24.5% reduction in average query retrieval timelines alongside an 18.2% enhancement in overall indexing resource utilization compared to traditional R-tree and quad-tree baselines. The memory footprint for index paths scales linearly, establishing a reliable storage blueprint for massive geospatial repositories.
