Singapore Land Authority (SLA) publishes the national cadastral parcel map as authoritative geospatial open data updated weekly. Polygons approximate surveyed lot boundaries across Singapore in GEOJSON and KML formats. Property researchers, conveyancers, and civic hackers can join parcel geometry with tenure or transaction tables for spatial analysis. The layer underpins many Singapore land-administration and urban analytics workflows on the open data portal.
