This presentation explains how large-scale 3D geospatial data for Thailand is managed efficiently. It covers the dataset’s scale and the reasoning behind organizing data using Google’s S2 grid system to improve management and processing. The talk explores the differences between using a single tileset versus multiple tilesets, and how virtual tilesets enable the efficient combination of thousands of 3D assets. Attendees will gain insights into the data and the key benefits of virtual tilesets, including enhanced performance, flexibility, and improved 3D visualization quality. Whether your work involves urban planning, disaster management, or geospatial mapping, this session offers practical strategies for handling complex 3D geospatial datasets.
