PMTiles raster maps for timeseries data

[brandao-andre]

Hi @bdon!

I’m new to Protomaps, but I’m really excited to learn more about the project! I’m working on creating a map with raster data from weather forecasts, and I’m a bit unsure about how to handle the time dimension, as PMTiles itself doesn’t natively support a time axis.

I’ve been following the AWS tutorials, and the results so far have been great. However, I’m trying to figure out the best approach to represent time-series data. Specifically, I’m considering two options:

• Creating multiple PMTiles files, where each file represents a single timestamp.
• Creating a single PMTiles file where each band represents a different timestamp.

Could you please advise on which approach would be more suitable for this use case? Any guidance or suggestions would be greatly appreciated!

Thank you in advance for your help!

There isn't anything timeseries specific in PMTiles, but you can store date data as strings in vector tile tags and then manipulate those in MapLibre styles, within a single PMTiles archive. An app I have seen that seems to do this is: https://lens.pathandfocus.com/
