Contributions
The Skyline Project renders building footprints in MapLibre GL and adds address search, click-to-inspect panels and curated landmark stories. A shared map engine uses separate configurations and data for New York, San Francisco and Central London. The London edition identifies official Ordnance Survey footprints and published construction-age bands. Open datasets make local use possible without a paid map service, while completeness and historical precision still depend on the source data.[4]
