Abstract

This paper presents a transformative approach that allows for the utilization of existing 3D models from diverse sources within a geographic context. It introduces the concept of external metadata, which describes these models, making them searchable, accessible, and seamlessly intergrated in webGIS environments using Three.js and MapLibre GL. This paper addresses the demand for the reuse of three-dimensional data representation in the geospatial domain and acknowledges the wealth of 3D models available from various sources. By introducing a standardized metadata schema, it establishes a structured framework for the incorporation of these models into webGIS systems. A central theme of this work is the development of a metadata standard that acts as a bridge between 3D models and webGIS environments granting it all information that can be used to correctly locate, scale and orient the models. It enables efficient searching, rendering, and utilization of these models within geographic contexts. Leveraging MapLibre GL JS and Three.js, the paper showcases how external metadata can significantly enhance the integration of 3D models into webGIS, thereby fostering a more versatile and comprehensive geospatial data exploration experience.
