GInfo Hong Kong: Smart Geospatial Infrastructure for Landslide Risk Management

The Geotechnical Engineering Office (GEO) of the Civil Engineering and Development Department (CEDD), HKSAR Government, developed the Geotechnical Information Infrastructure (GInfo) to systematically manage Hong Kong’s landslide risks, an urgent necessity in a densely urbanized environment surrounded by natural hillsides and over 60,000 man-made slopes. Initiated in 2009, GInfo is a robust, web-based GIS platform built on Esri ArcGIS technology, integrating vast geospatial datasets including slope inventory, LiDAR topography, aerial images, drillhole logs, and maintenance responsibilities. It offers an advanced and user-friendly interface for professionals and the public to access, analyze, and act on slope stability and maintenance data. The system's core strength lies in its spatial geoprocessing functions which enable slope engineers, city planners, and government bodies to perform real-time analytics for informed decision-making and disaster mitigation.
