Re: [talk-au] New tile rendering server (Experimental)
Does that mean it will be easier (therefore more likely) to improve the rendering of OpenCyclemap? That would be good. - Original message - From: Grant Slater [1]openstreet...@firefishy.com To: [2]dbcl...@fastmail.com.au Cc: talk-au [3]talk-au@openstreetmap.org Subject: Re: [talk-au] New tile rendering server (Experimental) Date: Tue, 23 Jul 2013 15:36:15 +0100 On 23 July 2013 15:08, David Clark [4]dbcl...@fastmail.com.au wrote: Sorry I don't really understand this, how will this affect me and what I see? Hopefully you shouldn't see any difference. :-) It is a large behind the scenes change on how we produce the default map tiles (view) for OpenStreetMap.org The old map stylesheet was a mass of difficult to understand XML. The new map stylesheet is completely re-written in a much cleaner CartoCSS syntax. Easier to maintain and improve, it is also easier to customise it for other projects. Andy Allan's talk explains it better than I could to: [5]http://vimeopro.com/openstreetmapus/state-of-the-map-us-2013/video/6 8093876 We have also changed the server infrastructure used for rendering the map tiles. The old server was becoming very complicated to maintain and administer due to the many layers of complexity, code, and undocumented hacks built up over time. The new server is setup using an automated devops system (opscode chef).

[talk-au] Garmin maps with style and typ files combined
Hi All Thanks to the to notch support from a local OSM Australia forum member and support from a generic OSM form and two excellent type files from French mappers I finally developed a very good starting point for a Garmin Bushwalking map, and here is the link to a drop box, https://www.dropbox.com/sh/g7nxh1xwjrlxg5v/O9sBszLB0n with the resulting img. Now while far from perfect the img does have a few useful features. The typ file allows customisation of line types, polygons and icons. I have stolen a few icons from a French developer (via La France) that match the mapnik ones. Also created my own one for scree and minor mountains. I started with the default mkgmap default style sheet. Big thing to note is as mkgmaps is developed for Unix programmers all the directory links are / rather than \ so the include additional style sheets does not work until the slash is reversed for Window users. I then used the typ file from a French programmer that did a wonderful job mirroring the standard mapnik icons. Then for additional icons I found another French typ file from someone that is very artistic on designing icons and borrowed his waterfall icon, and will be liberating a few more. Plus as mentioned added my own style for scree. Also I modified the generic mapnik type to remove icons that are standard Garmin ones, as Garmin did a better job of rendering the icon. Thanks to the kind support of a fellow OSM Australia mailing list member I have added in the contours for 20 metres. Also I changed the resolution levels for paths to hang into 12 km and increased the number of levels by two. My contribution to the default style and mapnik typ file is three mountain types, 1000 metres, 1000-1399 metres, and 1400 metres. This means screen clutter is not such an issue. Also upped the standard resolution for contours and minor roads. Made the line type for paths more visible. So we now have alpine hut icon as well. The img should be routeable and with a street index. Anyway, the above is only for Tasmania as an experiment. Next step is playing with the road rendering as per my earlier email suggests. So have a look and any comments appreciated. More than happy to share my style and type files plus write up instruction for Window users incoming to terms with mkgmap.
