Q: Can SPACIAL AI sort data types using tokens (like LLMS) to ingest a "point clouds" (LAS/LAZ/e57), MESH, NURBS,.. or event photos into a single source of truth w/ layered options (like a multi-verse) that can output simple geo-located fixed geometry for reference that offers various rendered details of reality.
ISO 19115: The global standard for geospatial metadata, ensuring 3D datasets are discoverable and well-documented
Open Geospatial Consortium (OGC) https://lnkd.in/ezWxiym4
is the primary body for developing open 3D geospatial standards.
13+ DATA TYPES
CityGML: A comprehensive XML-based data model for representing 3D urban objects like buildings, vegetation, and infrastructure. It includes levels of detail (LOD) for varying complexity.
3D Tiles: Designed for streaming and rendering massive 3D geospatial datasets over the web, such as photogrammetry and point clouds.
Indexed 3D Scene Layer (I3S): An OGC community standard optimized for streaming large 3D datasets to web, mobile, and desktop clients.
CityJSON: A JSON-based alternative to CityGML that is more developer-friendly and compact for web applications.
IndoorGML: Specifically focused on modeling the internal spaces of buildings for navigation and location-based services.
3D MESH:
glTF / GLB (Web & AR/VR) "JPEG of 3D," it is highly optimized for fast loading on the web and mobile.
OBJ & FBX: Traditional 3D graphics formats commonly used for individual models, though they lack native geospatial coordinate support.
BIM & Construction:
IFC (Industry Foundation Classes): An open standard for Building Information Modeling (BIM) that often integrates with 3D GIS for urban planning.
FBX (Gaming & Film) A versatile container that stores geometry, high-fidelity textures, lighting, and complex skeletal animations.
OBJ (Static Models)
One of the oldest and most widely supported formats; simple and reliable for exchanging geometry without animation.
USD / USDZ (Collaboration & Apple AR)
Developed by Pixar for massive scene management; popularized by Apple for AR experiences on iOS.
STL (3D Printing)
Focuses strictly on surface geometry as a series of triangles; contains no color or texture data.
STEP / IGES (Engineering & CAD)
Mathematical formats used to exchange precise product data between different CAD software.
3D Model of London buildings are now available for purchase and use as a Forma Contextual Data Market Card.
If you are an Autodesk Forma user in #London, you can now purchase this high-quality #LOD2 data from AccuCities® 3D City Models directly within #Forma, with instant access and direct integration.
For building sites outside of city centers, Forma users can order custom 3D models directly from the AccuCities website and we will deliver the site model in a format and coordinate system fully compatible with Forma in just a few days.

3wFallingwater was my introduction to what it means to design for permanence. Seeing technology used to preserve that legacy rather than replace it - that's a harder and more meaningful problem than most people appreciate.
