I'm the developer of Protomaps, to summarize: The latency you see on https://pmtiles.io/?url=https%3A%2F%2Fdata.source.coop%2Fpro... is representative of how PMTiles works on AWS S3, coming from the us-west-2 region. It will be reasonable to load for those in the western US and likely quite slow from Europe or Oceania. If you want to make a direct comparison of Protomaps to OpenFreeMap, you need to compare serving Op…

No, the ping is 150 ms to us-west-2, and the tiles load in like 5 seconds on a cold start. Of course we cannot test cold start on HN comments because HN is the definition of hot :-) I can imagine workers to be fast, it's the range requests which are super slow. It's also outside of your control, it depends on how Cloudflare and S3 handles range requests to 90 GB files. I think if you could make PMTiles split into fil…

I agree, there are tradeoffs to using static storage - the intended audience for PMTiles is those that prefer using static sites instead of administering a Linux server.

I would be interested to see a comparison of Btrfs + nginx serving latency, vs `pmtiles serve` from https://github.com/protomaps/go-pmtiles on a PMTiles archive on disk. That would be a more direct comparison.

I think there's potentially some interesting use case for tiles in Btrfs volumes and incremental updates, which I haven't tackled in PMTiles yet!

So Protomaps is a really full stack map platform, they are competing with kind of like 3-4 projects at once: - There is the Protomaps schema. It's competing with OpenMapTiles and Shortbread ( https://shortbread-tiles.org/ ) - There is the Protomaps file format. It's competing with MBTiles and say Btrfs images in OpenFreeMap. - There is the Protomaps styles. It's competing with OSM Liberty and OSM Bright styles ( http…

1) The Protomaps schema is mostly a re-implementation of the Tilezen project https://tilezen.readthedocs.io/en/latest/ which is a linux foundation project. OpenMapTiles, which OpenFreeMap uses, while open source, does not have a license that encourages derivative works or enables distributing styles under a standard FOSS software license ( https://www.npmjs.com/package/protomaps-themes-base ). That's also one motivat…

Can you elaborate on this ? I'm derivating OMT and am quite worried now ^^

I currently use the cyclosm[1] as a tile map for my small web app. I'd love to use OpenFreeMap instead, as cyclosm is quite slow. Is there any way I can do this for bicycle maps? Awesome project. [1] https://www.cyclosm.org

As far as I know, no vector equivalent of cyclosm has been made. OpenMapTiles's data are too poor ("compressed" : different cycle way types are summarized in a unique tag) to make a great cycle map.

For this use case i would use the bunny volume tier which is $5/TB

That's still an order of magnitude more than what you can get with rented servers. I pay between 0.2 and 0.4 per TB doing nearly 2000TB a month.

Agreed. Getting a dedicated fibre link colocated is a great way to backfill and push the free tiers of CDNS.

Just like the cloud becoming easier to run on your own environments, tons of bandwidth is accessible too.

OMT use a CC-BY license: https://creativecommons.org/faq/#can-i-apply-a-creative-comm... (edit: link)

This means that software that implements OMT, even if written from scratch, cannot be re-used by other FOSS projects (Apache, BSD, GPL, AGPL, other software in the OpenStreetMap ecosystem, etc) without affecting the license.

Ideally for Protomaps it should be possible to re-use just one portion - like only the label layer with your own layers from other sources, or even bundle it as a JS dependency in another open source project - without affecting the license of downstream projects.

I miss some libre client for Google's Street View. On 3D maps, adapting Marble for OSGEarth should be a piece of cake. If not, declaring one with IMGui+layers can be done in a week from any experienced C++ programmer. The included demos for OSGEarth already depict a minimal client with impressive 3D maps for a nearly non-supported demo. I think KDE/Plasma lost a great oportunity there by not adopting OSGEarth.

What would be the aim of a libre client for Google's SW ? Street View API is quite expensive.

Do you know about https://panoramax.fr ?

Thanks ! I've thought about making an "education" project but it takes time, and after 9 months of working on it I'm now convinced it's possible to build a basic Gmaps alternative in a few years. Business model still missing though !

Edit : just watched some minutes, he's rebuilding low-level components, like route finding. Impressive stuff but not quite user-friendly.
