Hi, i'm looking for a way to change the maximal zoom in renderd. Actually, it only renders tiles with a maximal zoom set to 18, and i would like to render some tiles with a 19 or 20 zoom. Do you know how i can perform this? Thanks. asked 13 Sep '12, 14:00 Lght |
MAX_ZOOM is not a configurable parameter, but has to be changed in config.h before compiling renderd. answered 17 Sep '12, 19:34 mmehl Thanks for your answer. The first thing i've done when i wanted to change the max rendering zoom was to check for a MAX ZOOM macro in headers file. I changed it to 19 or 20, but even after the compilation, i'm not able to render a image linked by http://localhost/osm_tiles2/19/266543/176364.png (it 404, and it was generated by OpenLayers), whereas this work http://localhost/osm_tiles2/18/133271/88182.png. The daemon i started was the one i just compiled. Maybe you have some ideas about that ? Edit: i forgot to restart my apache server the first time. Thanks.

For zoom levels up to 20, I added a user wiki page describing the changes that I needed to make to render, update and display maps. answered 02 Jul '16, 11:11 SomeoneElse ♦ |
Hi, I found a solution just passing a few parameters to OSM layer when it is created.

As I understand it, the zoom levels are each rendered and stored separably so although there are ways to magnify the screen image,with Ctrl + in windows for example,you are probably limited by the system to level 18. see http://wiki.openstreetmap.org/wiki/Zoom_levels answered 13 Sep '12, 16:44 andy mackey |
You'll probably get more response on the osm-dev list or #osm-dev in IRC. A quick search such as
"zoom 21" site:lists.openstreetmap.org/pipermail/dev/
finds a few old list messages (obviously try other numbers > 18 as well as 21).
Thanks.
I've searched in those pages, changing few words in the hope of finding a solution but i'm still blocked with that.
I'm going to ask my question in #osm-dev.
