Re: [OSM-dev] OSM customization problems
Jochen, Yves, thanks for your attention. When I stop rendered: root@abcdef:/# ps -ef | grep renderd root 40901 38529 0 15:24 pts/000:00:00 grep --color=auto renderd And I request HTTP to clean a tile, it still answer: "Tile submitted for rendering" And when I ask for tile´s status: Tile is clean. Last rendered at Thu Dec 06 19:37:30 2018. Last accessed at Fri Dec 07 12:56:14 2018. Stored in file:///var/lib/mod_tile/default/14/0/33/223/20/0.meta (Dates might not be accurate. Rendering time might be reset to an old date for tile expiry. Access times might not be updated on all file systems) I thought that renderd was in charge to answer for Apache ModTiles, but I stoped renderd, restarted Apache but dirty/status stills answer. And still nothing changes to applying style. Andy, I am reading lots of documents. I will check those too. Thank you, Koji > - renderd.conf XML property, points to a style file.

Also, in addition to the software that openstreetmap.org uses you have lots of other options for rendering map tiles using completely different software, and various providers who can help you along the way.

Re: [OSM-dev] OSM customization problems
Yep, renderd as to be restarted and it's a good thing to run "tail - f /var/log/syslog | grep renderd" in another terminal while restarting to see if the style loads without errors. Apache also needs to be restarted if you change renderd.conf.

[OSM-dev] OSM customization problems
Hi all, this is my first post here, and at first I would like to congratulate you all for this great ecosystem of the OSM. If my question doesn´t fit to this chanel, please tell me. English is not my main language, so I will do my best to be clear. I am just starting to use OSM to move from GMaps. We already have the infrastructure set to render and to serve maps via Apache (mod_tle). The processo seems to be very slow to render the whole planet, but it is working. This is for another thread. What I am trying to achieve is to execute some small parts of the complete process, which very simplified,is: - Dowload data (.osm file) - Import to Postgres - Serve tiles Considering that the whole infrastructure is up and runnig, I have already downloaded Maldive Islands data to perform import/render process to acquire the necessary knowledge of all steps of the whole process. Here I have some questions: - I am using mapnik to style the maps, but it is not clear for me that the style is applied while importing data from osm to database (and stored inside db data), or when the tile is rendered. - renderd.conf XML property, points to a style file. I change this file but the changes I made doesn´t show on tiles, even if I reload data to database, and even if I mark the tile as "dirty" to force re-render. This is the reason for the first question, that I can not even understand when the style is applied, during import, or during render. - I tryed to check the png data direct on disk, but I couldn´t find it using this steps from here ( https://github.com/openstreetmap/mod_tile/blob/master/readme.txt) : " /[base_dir]/[TileSetName]/[Z]/[]/[]/[]/[]/[].png Where base_dir is a configurable base path for all tiles. TileSetName is the name of the style sheet rendered. Z is the zoom level. [] is an 8 bit number, with the first 4 bits taken from the x coordinate and the second 4 bits taken from the y coordinate. This attempts to cluster 16x16 square of tiles together into a single sub directory for more efficient access patterns. It is ok for me up to the zoom level.
