[Talk-pt] New tile rendering server (Experimental)

[Grant Slater]

Hi Spain & Portugal,

**Sorry for this email only being in English. I would appreciate it if
someone could translate this message (or summary) for list members.**

I have just switched the default OpenStreetMap.org “Mapnik style” map
tiles for tile.openstreetmap.org for Spain and Portugal across to our
new rendering server.

The new rendering server has been tested and is now ready for
production. We’re migrating traffic over region-by-region and Spain &
Portugal are the third region to go live (After Australia + New
Zealand & Mexico).

In addition to new hardware, the rendering server also uses the new
“openstreetmap-carto” stylesheets. These are a complete re-write of
the XML stylesheets to use CartoCSS, making them easier for our
cartographers to work with.

Andy Allan’s great talk at State of the Map US described the reason
for the stylesheet re-write:

The map tiles will be slightly slower at medium-high zooms while the
server builds up its cache. The style is designed to look the same as
the current XML stylesheet.

The “openstreetmap-carto” stylesheet is maintained here:

Big Thank you to #osm-dev for helping draft this announcement.

Kind regards
