Hi, I'm trying to set up a map server using mod_tile, when editing the render_config.h file to fit my directory hierarchy there are some parameters I don't success to understand:
1.- IMG_PATH: 'grep'-ing all mod_tile files lead that IMG_PATH is only defined in render_config.h and is never used. But in the definitions it says that must contain blank.png and other files. Advice please. 2.- In the readme.txt file it says that the file osm-jb-merc.xml define the Mapnik rules. This is 'my' osm.xml file? and defined in OSM_XML in render_config.h. The different names cause me a bit of confusion. 3.-I don't fully understant how PLANET_TIMESTAMP and PLANET_INTERVAL work. PLANET_TIMESTAMP is used in the render daemon, so if the file is missing the daemon will rerender when a tile is 3 days old of its expiry (line 68 render_list.c -> planet_timestamp = 3 * 24 * 60 * 60;) if the file exists only rerender when the date of the file changes. I understood it well? For PLANET_TIMESTAMP used in mod_tiles.c is the same that in render_list.c and PLANET_INTERVAL is the interval added to calculate the expiry date of a tile. Correct? 3b.- I suppose the I don't understand it because rerender should happen only if the PLANET_TIMESTAMP file is touched or the render_all script is executed. 3c.- While writing, I think I do not understand nothing about when rerender happens.... :( 4.- The update script has to be called manually (or croned). The mod_tile nor the render daemon will try to update the planet file. Thank you, Jaume. _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/listinfo/dev
