I'm slowly working on my manifesto for the election, and writing my answers to the suggestion questions. I'll let yous know when it's done

All / members are still able to ask board candidates any questions they want. ๐Ÿ™‚ If you have any questions for me as a candidate, please feel free to ask.

@rory Would you Support
an homepage using vector graphics
an server offering vector tiles

@karlos yes I would support that. ๐Ÿ™‚ (that's one of the official questions, so there's more written there too)
I gave a talk at SotM about porting the osm-carto style to vector tiles. I have tech experience with this.

Alas vector tile tech is often a PITA, and I think that'll be the main problem ๐Ÿ˜”

@karlos there are many design decisions when it comes to vector tiles, which affect things. Like do you require only js/client side rendering? Do you redo the style or port OSM carto? Etc

@karlos I really like RichardF's idea for vector tiles. Ah someday....

@rory Looks like I will get lost if i start to read about topic Vector Tiles. To many experiments, arguments, discussion paces. As a first step, this needs organized.

Even the topic "Vector Tiles" are not clear. To me it is files with vector data. An (web-) app with individual styles will render, may be even in 3D.

* I can't find "vector" on the (official) questions page.
* I found your speak: 2016. Well, I would start with a style-shape mimic Carto an let the user make variations.

* JS? Yes, but not only. WASM of course. A renderer on Git with C++ or RUST to use anywhere.
* More but client? Hm, a server rendering bitmaps with all the advantages of vector: seemless zooms, switching styles, filtering POIs, ...

RichardF? You mean github.com/systemed/tilemaker - yes, we need one/some "standards" what tiles will contain (and how coded). May be additional tiles, if you need 3D data i.E.

I would like to help, if a project exists.
Except "I may be to old for this"

@karlos This is RichardF's call to arms about vector tiles. It's a great idea blog.systemed.net/post/15

You're right there's no vector tile question, but my answer to multilingual maps talks about them, which is why I thought it was there.

@karlos alas, there just isn't a lot of rendering software and it's a PITA. There's mapnik, mapboxgl, tangram, ish. There's just a lot of lacking software, and companies like Mapbox have moved on & Mapzen are gone.

@rory Lacking software? Web search about OSM vector render software seems to take days. Most of it is commercial and I am not amused about Mapbox either.
* Tangram looks good. There is also C++ usable with WASM for a (Progressive) Web APP
* Mapnik is C++ and Python. Hm?
Why not use one of them?
I wouldn't mind to start from scratch and just use the logic of Carto, not the code.
What would you like, C++ or Rust?
I wrote OSMgo.org as a 3D renderer, just a small part of what we need of course.

@karlos So I don't want to damp your eagerness. If you wanna make something, then please do it. vectortiles on OSM.org would be _great_!

@rory ๐Ÿค“I started to learn/use Rust and WASM. The idea is to code an example, how OSM vector rendering could be done.

Could OSM found a taskforce to list needed steps and work out ways to solve them?

@karlos I've been playing with too! ๐Ÿ‘

TBH I think you just have to take the lead on it yourself. Just make some software that does something.

@rory ๐Ÿ˜’ I try to do
but the call from JS to WASM
does not work.
I need a running example ...


@karlos I've been programming rust, but I've never done any wasm stuff I'm afriad... I dunno.

@rory It's running! My live is saved, all depressions avoided.
I just forgot to copy one line at the class implementation:

Ok, some more training is needed first.
Meanwhile I will contact RichardF just for a talk. I am sure, there is a ready to use code to read his tiles.

@karlos yay!

I have written a crate to read/write MVT files ( github.com/rory/rust-mapbox-ve ).

The MVT format is very simple. It's just a simple protobuf format. That's not really the hard part. IME it's doing all the graphics & rendering & stuff. I've half started something which renders MVTs as image using cairo (which is what mapnik uses too).
