#Meta is sun-setting their Daylight Distribution in favor of putting their efforts behind #OvertureMaps 🗾

It makes sense as Meta was a Overture Maps Foundation founding member, together with Amazon, Microsoft, and TomTom.

The Daylight land cover dataset was pretty solid for self-hosted maps with #Maplibre & #Protomaps

@jez @djh This is largely right. We haven’t done a good job at explaining this. But there’s more in Overture. Daylight had few checks on admins (why we had it in a sidecar) but there’s a lot more in Overture. Also better validation of the road network than Daylight had.

@jwass2000 @jez Awesome! This is nice to see! I read the post and would love to understand more about

1. What's the license of the landcover dataset now?

2. Do you have validation metrics on the derived landcover classes? As in: how accurate is this dataset (per class, per geography, etc.)

@jwass2000 @jez also if I get this right it'll basically never update.

Does it mean it reflects landcover from this year or last year during summer time?

Especially on high resolution, don't the landcover polygons change over time?

That would also be an opportunity to reflect the seasons and change we experience on Earth in a dataset 🌍✨
