Mar 1, 2025March 2025 — Geoviite (finnishtransportagency/geoviite) delivered notable features and stability improvements across geocoding, memory management, and geometry visualization. Key features include faster geocoding through memory optimizations and a cleaned interpolation API, plus an enhanced vertical geometry diagram that exposes the current layout context. Major bugs fixed strengthen memory stability and geometric robustness: a memory leak in LocationTrackSpatialCache was removed by eliminating duplicate references and simplifying segment storage; degenerate bounding polygons were expanded to sensible bounding boxes with accompanying tests. Overall impact: reduced memory footprint, faster and more predictable geocoding, more robust geometry processing, and clearer developer ergonomics through API refinements. Technologies demonstrated include memory profiling and optimization, API refactoring, and geometry robustness testing.
