Sessions
In this session, I will introduce mago3DTiler (https://github.com/Gaia3D/mago-3d-tiler), an open-source OGC 3D Tiles creator that has gained global popularity thanks to its robust features, high performance, and user-friendly interface. Initially unveiled at FOSS4G-Asia 2023 in Seoul, mago3DTiler supports over ten different 3D data formats, including 3DS, OBJ, FBX, glTF, Collada DAE, BIM (IFC), LAS, LAZ, and SHP. One of its standout features is on-the-fly Coordinate Reference System (CRS) conversion during the 3D Tiles creation process. Additionally, it allows users to convert 2D data with height attributes into extruded 3D Tiles.
During this session, I will also demonstrate how to create a digital twin using mago3DTiler in just a few minutes. This tool makes complex geospatial tasks more manageable, especially for users looking to integrate diverse data formats seamlessly into 3D projects.
The range of AI applications in the geospatial information field is diverse, object detection, area extraction, change detection, and super-resolution. In our industry, we collectively refer to these technologies as GeoAI.
However, these technologies remain primarily confined to specialized groups, making it difficult to consider them as universal technologies ready for everyday use.
In light of this, we sought to explore areas that could be easily accessible to the general public. Consequently, we developed 'magoGPT', a application enabling users to manipulate maps and interact with 3D objects using natural language in a digital twin environment.
Based on a 3D FOSS architecture composed of CesiumJS, it uses 3DTiles buildings, Terrain from high-resolution DEMs, and multiple layers visualisation. It is also related to artificial intelligence techniques such as Large Language Models (LLM), Speech-to-Text (STT), and Natural Language Processing (NLP).
In this presentation, we'd like to introduce magoGPT, the technology behind it, and the development process.
