Guidance on Using GeoWave for Large-Scale High-Precision 3D LiDAR Data

[bloom256]

Hello GeoWave Team,

Our team is working on a large-scale project that involves capturing and managing trillions of LiDAR data points from urban scans worldwide. Currently, we use .LAZ files to store this data in Earth-Centered, Earth-Fixed (ECEF) coordinates, with each point having attributes such as return number, intensity, classification, etc. We are exploring GeoWave as a solution for distributed storage and efficient querying of this data.

From the documentation, it seems a custom data adapter is necessary for 3D data handling, but I have a few key questions:

1. Achieving Millimeter Precision
   For our detailed urban models, global millimeter precision is essential. In .LAZ files, ECEF coordinates provide this precision seamlessly. Would GeoWave support this precision effectively if we stay with ECEF, or would lat/lon/alt coordinates be preferable? If lat/lon/alt, we would require a significant number of decimal places for 1mm global precision.
2. Unified Dataset Structure
   We aim to manage all LiDAR data as a single dataset for analytical tasks, not as separate GeoWave datasets per .LAZ file. Could you provide guidance on configuring GeoWave and choosing an optimal data store to handle this?
3. Creating a Custom Data Adapter
   Could you provide advice or point to resources on building a custom adapter for 3D data, especially with high precision and additional attributes?

Thank you for your help and any recommendations you can provide to us!
