Vibes are all that matter. As soon as you start measuring it, that measurement becomes a target and vendors start optimizing for it at expense of the general usefulness of the mode…

Cool! I definitely felt the pain of current options when I added parquet support to Planetiler to process overture data. I ended up using parquet-floor to trim the dependencies but…

Planetiler currently supports generating MLT by adding —-tile-format=mlt cli argument. It’s only on latest main right now but I should be able to get a release out in the next few …

Pole of Inaccessibility is also a useful technique for placing the label for a polygon at a visually pleasing location on a map. @mourner came up with a more efficient algorithm fo…

I haven’t used markdown in javadoc yet but this seems like at least 3/10? I often want to put paragraphs or bulleted lists in javadoc and find myself wanting to use markdown syntax…

A friend of mine is on a 25 year running every day streak. He flew to Australia and landed 2 days after taking off and said that day “never existed for him” ¯\_(ツ)_/¯

I’ve stopped at that Lee McDonald’s and remember thinking the price seemed kind of high. Little did I know it was the most expensive in the country. Even the eastbound one across I…

I’m looking forward to be able to memory-map an entire large file without having to split it up into 2gb segments, and to be able to reliably unmap it when done. So many hacks to w…

I came up with an approach for placing labels where each gets a min zoom to show up at such that there are no collisions and always appears beyond that. Personally I like the feel …

The protomaps basemap is also built on planetiler: https://github.com/protomaps/basemaps - and Brandon is one of the main contributors a to planetiler!

Exactly, this use case is write-once then read-only after that. Random updates to the sqlite file after that would need more “normal” settings, but they wouldn’t also need as much …

I spent a while optimizing sqlite inserts for planetiler, this is what I came up with: https://github.com/onthegomap/planetiler/blob/db0ab02263baaa... It batches inserts into bulk …

I built planetiler ( https://github.com/onthegomap/planetiler ) for this purpose. The output up to z14 is ~80gb and depending on how big of a machine you have it takes from 30 minu…

You may have chosen Valhalla for other reasons, but FWIW I’ve found Graphhopper can handle 1-2 orders of magnitude more qps than Valhalla on the same hardware.

We’ve been experimenting with R2 for serving tiles from an 80gb pmtiles archive, unfortunately the latency on up to 3 byte range requests from a worker is 5-10 seconds so it’s not …

You can track progress for planetiler producing pmtiles output here: https://github.com/onthegomap/planetiler/issues/98 . Another bonus of writing pmtiles directly is that it will …

Another option if you want to offload the tiles from embedded in your docker image to static file hosting would be to convert the mbtiles output to pmtiles [1]. Then just upload th…

Nice! I was going to point out the project I’ve been working on [1] to reduce the cost but I see you’ve already found it :-) Feel free to reach out it you run into any issues! [1] …

I recently found this approach: https://github.com/onthegomap/planetiler/blob/main/planetile... but I’m hoping this api will eventually let you do that without an external dependen…

I have a google sheet where I keep track of each fund I’ve bought and sold. From there I added a column with gain/loss for each tax lot with remaining shares, and a script that run…

I make a photo book once a year with the best photos from the year. I use Amazon photos, google photos, etc but the hard copy book is the only one I’d expect to still be around in …

Yep, that first one will do it! And you probably want to rip out the polygon merging code and minimum zoom on the attrs. You can use --only-layers= or --exclude-layers= if you don'…

The main driver of memory usage (~1.0x the input file size) is storing node locations so we can convert the list of node IDs on each way into lat/lon coordinates. By default nodes …
