basemaps VS planetiler

Does not have routing etc but https://basemaps.linz.govt.nz/ may be a viable option.

New Zealand regularly uses flying companies to take aerial imagery photos of most of the country, which is generally taken between 30cm and ~2cm, Land Information New Zealand (LINZ) then releases this imagery imagery completely free (CC-BY)[1,2] to the public and can be downloaded as GeoTIFFs [3]

I think LINZ decided that <0.05m might have some privacy issues due to being able to distinguish people in it, and have held back releasing some <0.05m or they may have reduced the quality of it.

This is also a really good option OP. Generally for aerial imagery in NZ, Retrolens is good from the 40s to 80s, Google Earth Pro desktop app (which is free) is good from 90s to early 2000s, and LINZ Data Service or LINZ Basemaps are good for 2010s to current day.

The address data is freely available from the NZ Street Address layer on the LINZ Data Service. The imagery is freely available from Toitū Te Whenua Basemaps. Both are released under a Creative Commons Attribution 4.0 International licence.

Worth mentioning this project (https://github.com/onthegomap/planetiler) that lets you create osm mbtiles and pmtiles pretty easy!

For a self-hosted vector tile stack you can have a look into https://github.com/onthegomap/planetiler I found it very easy to get started and when you know the other stacks it is also very fast to create these vector tiles even for planet-scale.

(note, that I'm not affiliated with them, but they use some source code from us for the efficient import and also contributed to GraphHopper, but this did not influence my experience ;) )

> I wonder why so many seem to be moving away from raster tiles to vector data.

The flexibility of styling. And you can easily serve customers that need different default languages. This makes maps also more accessible for countries without Latin alphabet.

I used https://github.com/onthegomap/planetiler and https://download.geofabrik.de, maybe it helps.

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 statements and is able to do writes in the 500k+ per second range, and reads are 300-400k/s using those settings.

Super easy way to generate a MBTiles, which you can then serve directly, or further convert to PMTiles, which can be used to host vector tiles for client-side rendering using MapLibre (or other renderers).

Raster tiles are a lot harder because you have to generate them on the server, and that's a lot more resource intensive.

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 minutes up to a few hours - no DB required, just java or docker. If you are only going to z11-12, it should be quite a bit faster/smaller.

Brandon from Protomaps is also helping add pmtiles output natively to planetiler, so you won't need a conversion step afterwards!

It's not raster directly, but you could use planetiler ( https://github.com/onthegomap/planetiler ) to build a full planet vector map . Then you could use something like TileServer-GL to server the vector map with a style. TileServer-gl ( https://github.com/maptiler/tileserver-gl) would provide a raster source that displays in the style you set on your vector map.

I recently left Twitter after 9 years, most recently serving as tech lead for the knowledge graph group (was 45 people). I helped apply the KG to drive a large portion of Twitter’s revenue and new product launches. In my spare time I do data visualization and web mapping, most recently https://github.com/onthegomap/planetiler
