Singapore Land Authority open geospatial data defining cadastral airspace parcels across the island, available as SLA Cadastral Airspace Parcel in GeoJSON and a companion KML export. The layers depict surveyed outer perimeter boundaries for each airspace parcel, supporting aviation, surveying, and 3D land-administration GIS workflows. Planners, engineers, and researchers can overlay airspace limits with cadastral and development datasets when studying Singapore vertical land use and spatial regulation.
This dataset depicts the entire Cadastral Airspace map of Singapore. This dataset contains polygons which graphically show the approximate coordinated outer most perimeter boundaries (nearest cm) of each surveyed airspace parcel in Singapore.
GeoJSON cadastral airspace parcel polygons covering surveyed airspace boundaries across Singapore, published by the Singapore Land Authority with coverage from November 2025. Supports aviation planning, property air rights GIS, and 3D cadastral applications that need official perimeter coordinates.
