Which vector-based rendering did you use? I'm working on a new attempt at that here, though not WebGL-based: http://github.com/protomaps/protomaps.js so it would be valuable to know if it can get closer to what yo

A cursory search of media published in the last month [1][2] shows those can be used to productively communicate in Chinese languages. You can argue that it is outside of what is prescribed in a table, but if not Pinyin, then what writing s

So by your definition, are "biang", "kiang" and "duang" valid pinyin, considering those are pronounceable and understandable to millions of people, though they don't appear in your table?

There are plenty of other uses of Bopomofo: 1) as a faster electronic input method for Mandarin and other Chinese languages 2) in casual or abbreviated writing 3) in overseas education

Yes, I mean that it is a valid syllable in the orthography rules but that does not imply it can be pronounced sensibly.

There are plenty of other transliteration systems that might lead to more accurate pronunciations for English speakers in particular (as opposed to say, native Russian speakers); see Wade-Giles or Gwoyeu Romatzyh. The factors that led to th

It does use almost all vowels and consonants. “Ching” ㄔㄧㄥ is a technically valid syllable in the Pinyin system but does not correspond to any word in the dictionary.

If the developer does not need to deal with a long-running process abstraction, and is billed only by actual compute time and not idle time, I think the consensus is to call that "serverless"

Yes, though for zooming in to sufficient detail you will need recursive indexes if you don't want the initial fetches to be really huge. https://github.com/protomaps/pmtiles#specification

This is the approach I took with http://github.com/protomaps/pmtiles , though it's optimized for the very specific use case of going from Z/X/Y integer coordinates to binary blobs, and takes shortcuts to

I am working on making the set of information included in the tiles configurable via a JSON definition, kind of like Overpass Turbo if you've used that. The reason I'm doing it this way is because data completeness and performance

It can deal with relations more flexibly than PostGIS-based workflows, because the tiles are generated from a near lossless representation of OSM instead of having to convert to OGC Simple Features first. Can you email me at brandon@protoma

Thank you!

I think I've fixed this now, and it exposed some other problems in my code and build process... can you verify everything works? Thanks for reporting!

by bdon 5y ago
Yes, I'll look into this. Can you email me at brandon@protomaps.com or make an issue at http://github.com/protomaps/protomaps.js ? I may need to make a get a sourcemap-enabled build online as well.

I'd like to understand what you mean by doing it many times - do you mean for different areas of the world? I haven't thought about API access to the bundles in detail yet, but you can contact me via email at brandon@protomaps.com

For annotation UIs on the web I would check out how http://geojson.io works, the implementation is on GitHub: http://github.com/mapbox/geojson.io

That's exactly what PMTiles is for, and there's nothing in it specific to maps or geographic coordinates, just a Z/X/Y pyramid structure. I chose to support Leaflet for now because it is very popular; there's other

Author here, so there are a few options: 1) If your information belongs in OpenStreetMap, you can add it via an editor like the web editor at https://openstreetmap.org - this will also benefit all other OSM users. You can then &

It might sound funny, but making slippy maps in Web Mercator is emphatically not what people call GIS - GIS being: * The technical part of the academic Geography field * Data collection and mapping work done at agencies like the USGS and mu

Right now it's best suited for mapping applications focused on some part of the world - neighborhood, city, country scale - especially ones that might avoid using a hosted service. Think visualization projects built for clients, newspa

Thank you! Really appreciate the commitment to simplicity among the libraries I'm using like potpack, rbush, and polylabel. I did take a look at Kothic and agree the labeling is great; I did feel like I needed to write yet another Canv

The tile generation from PBF (actually OSMX) is not one of the parts that is open source; for that task I would look at https://github.com/systemed/tilemaker or https://github.com/openmaptiles/open

Author of OP here, I use the tile unpacker as well! I didn't point this out in the OP, but I found the ergonomics of uploading tiles to S3 etc get bad once you're over a couple tens of thousands of tiles, as each upload has some o

Author of OP here. Is this information that you're interested in contributing, and is appropriate for, OpenStreetMap? The end goal is to build a system that lets you customize the tileset to include any node, way, relation, or tag in O

Author here. You should be able to first download OpenStreetMap tiles in PMTiles format ( http://github.com/protomaps/pmtiles ) and then write out a new augmented tileset in the same format. It's a use case I want
