Abstract:

The desktop study stage is a fundamental component of geotechnical site investigations, requiring the collection, synthesis, and interpretation of diverse spatial datasets including geological records, hazard maps, service infrastructure, and planning documents. However, the fragmented nature of spatial data sources and the technical complexity of Geographic Information Systems (GIS) tools present challenges, particularly in educational contexts. This study presents the development and implementation of a web-based geospatial application designed to streamline desktop investigations for geotechnical engineering students.

The application integrates publicly available spatial datasets from Auckland Council, Watercare, and other authorities, converting complex GIS layers into interactive map visualisations and automated text-based outputs. Developed using HTML, CSS, JavaScript, and Leaflet.js, and deployed via Netlify, the platform enables users to input a property address and retrieve information on soil deposits, flood hazards, erosion susceptibility, volcanic field boundaries, zoning classifications, and infrastructure services. A case study at 20 Rochdale Avenue, Glendowie, Auckland demonstrates the application’s capability in supporting site assessment. Trial implementation within undergraduate geotechnical courses indicates enhanced student engagement, improved spatial reasoning, and stronger alignment between academic learning and professional practice. The study highlights the potential of web-based GIS tools to transform engineering education and outlines future directions for scaling the platform for industry and public use.
