Hi Richard

Thanks for clarifing these aspects.

To our defense, regarding scaling to the globe we actually just tried
to rephrase the README "It's best suited to city and region extracts."
[1]. So sorry for our interpretation.

Regarding additional data (as Shapefiles) the docs says "Tilemaker
chiefly works with OpenStreetMap .osm.pbf data, but you can also bring
in Shapefiles. These are useful for rarely-changing data such as
coastlines and built-up area outlines.". And: Lua transformations are
not available for shapefiles".

This would probably fulfill our needs since we actually are including
Naturalearth data from Shapefiles.

But is Tilemaker really suited to include completely arbitrary data
sources? Any use cases?

Regards, Stefan

[OSM-talk] Project OSM2VectorTiles.org launched

[Stefan Keller]

OSM2VectorTiles is a project simplifying installation of free world
maps maintained by OpenStreetMap community. It offers freely
downloadable OSM vector tiles, and a set of open-source tools to use
them and generate them.

Within minutes anybody who knows Docker can run on a laptop or private
server his own copy of OpenStreetMap map, with a customised design and
use it websites and mobile applications or in intranet - even behind a
firewall or without internet connection.

Feedback welcome!

Looks interesting - nice work!

If I may just pick you up on one statement in the thesis:

"There also exists a method[17] that circumvents using a database and
directly transform OSM data into vector tiles but this does not scale for
global vector tile coverage and does not support mixing additional data into
the vector tiles.

"[17] GitHub. Tilemaker, 2015. URL https://github.com/systemed/tilemaker.
Visited on 2015-12-14."

Whether tilemaker scales to the globe has not yet been attested. My hunch is
that it probably doesn't impose more demanding requirements than, say, OSRM,
which would mean it should be possible to create vector tiles from
planet.osm.pbf with a large memory machine or EC2 instance. I would be
interested to hear from anyone who tries it.

It does, however, very definitely support including additional data (in
shapefile form), and even allows you to perform some spatial queries using
this data. See
https://github.com/systemed/tilemaker/blob/master/CONFIGURATION.md#shapefiles
.

cheers
Richard
