URA Master Plan 2019 geospatial data includes an indicative underground structure and infrastructure layer approved with the November 2019 plan. GEOJSON and KML files highlight selective subsurface features for planners coordinating basements, tunnels, and utilities in dense Singapore. Engineers and GIS teams should consult ura.gov.sg for the latest Master Plan because this extract may predate subsequent amendments. The layer supports 3D-aware planning without exposing sensitive operational detail beyond published outlines.
