Summary
Niantic aims to develop a Large Geospatial Model (LGM) from user-generated data.
-
Current Progress: Niantic's Visual Positioning System (VPS) currently uses neural networks to accurately position users learn about the world. We recognize objects and environments based on past experiences and apply that knowledge to new situations. For example, we can identify a chair even if it's tilted or partially obscured. This ability stems from our brain's capacity to build a mental map of the environment, landmarks, and paths from one direction before.
-
LGM's Potential: An LGM would mimic this human-like understanding by learning from vast amounts of geospatial data for AI. The LGM will be able to:
- Geometry
- Architectural styles
- Relationships between objects
- How these objects are arranged in space
-
Benefits Beyond Positioning: An LGM's applications extend beyond accurate positioning. It could enable new ways to represent, manipulate, and create scenes. This type of versatile AI model is considered a "foundation model" and will likely work in conjunction with other foundation models like Large Language Models (LLMs) for a more comprehensive understanding of the world.
-
Challenges: Building an LGM requires massive amounts of geospatial data, which Niantic is uniquely positioned to collect due to its user-generated content. However, ensuring the model's accuracy and fairness while addressing privacy concerns will be crucial challenges.
This discussion revolves around Niantic's announcement of their "Lightship" platform, which leverages data collected from Pokémon GO players to create a global 3D map.
Here are the key takeaways:
Points of Discussion:
Overall Sentiment:
The announcement generates excitement about the potential of Niantic's 3D mapping platform, but also raises ethical questions regarding data ownership and accuracy concerns. Many see it as a promising step towards more immersive and interactive experiences powered by real-world data.
