We found a [hilbert implementation fast enough](https://github.com/rawrunprotected/hilbert_curves) that computing the start offsets was a bottleneck, the fastest way we found to do it was to precompute a lookup table, then...

Nice!

Has anyone considered accomplishing this by splitting up a larger pbf into smaller pbfs at tile boundaries then running tilemaker sequentially over them?

Planetiler currently limits to z14 but it should be pretty straightforward to increase if people want to go higher. The z14 limit was to support openmaptiles schema which only needs...

Awesome! I tried to make planetiler-examples an example standalone project, but maybe a separate repo would make it easier to grok? I'd be happy to bring in your example to...

Thanks for reaching out @bdon! Could you elaborate on exactly how that connectivity check would work? The line merging algorithm is pretty simple now, it just groups linestrings in each...

Ok thanks for the explanation. I think the first step here is to implement a custom line merge routine to be able to customize any of this stuff since the...

Hello! In planetiler this logic is controlled by the profile, which decides what zoom levels to include which features at. There is no inherent tile size limit and no density-based...

On a larger machine like that try -Xmx=120g and --storage=ram to store all node locations (80gb) and relation membership (10gb) in RAM. If you have less than 128gb ram then...

There are 2 memory issues going on there, the first one when it got killed was when the JVM got close to 180gb but sqlite was using some unmanaged memory...
