Land Transport Authority geospatial layers depicting retaining walls along Singapore’s transport corridor network. GEOJSON and KML datasets help engineers and planners identify structures that stabilise adjacent soil against erosion or landslide risk. Ad-hoc updates reflect asset surveys tied to road and rail infrastructure management. GIS teams can overlay walls with slope hazard studies and maintenance programmes. The collection supports infrastructure safety mapping on Singapore’s open geospatial catalogue.
A wall built to support the adjacent soil from erosion or landslide
This geospatial dataset maps retaining walls maintained in the context of Singapore's land transport network. Retaining walls support adjacent soil and help reduce erosion or landslide risk. The GEOJSON layer can support infrastructure mapping, asset planning and spatial analysis alongside roads and other LTA features.
