Hi Steph, just to make sure: There are no other error messages from splitter or mkgmap, right? And you used a clean directory without any possibly corrupted artifacts?

Please upload a single tile of bano data merged with OSM data to http://files.mkgmap.org.uk/ and the mkgmap options that you use with the default style.

My style is not so heavy for overview map and all modifications I tried to make it lighter failed. So I replaced my style with default style and mapnik typ within my scripts… that failed ! The fact is I merge a national addresses db (BANO -> http://bano.openstreetmap.fr/data) with the Geofabrik pbf before running splitter. If I don't make this merging, compilation run fine. So it appears that it's not an “esthetic” map particularity but address data which produce issues, if I got it right… And of course I don't know why 😂 Thanks again. Regards!

Hi Steph
I had these kinds of problems in my early days when trying to build a full-europe map. I'm not the expert, but what I find out was that it I looks like the overviewmap is one big *.img file And so combines everything you put in your lower overview levels 17,16,15,14 & 12 together Above the overview levels (18-24) multiple tiles are created giving you an 'endless' amount of space but for the overview levels its whatever fits in this one img file. There is a limit (don't know how much) (If I remember correctly I even had to wait 6 hours before at the very end the overview map was written and failed the process)
For me, it did not help to use less levels but just limiting the amount of stuf drawn starting from 12 to 17 I adjusted 98% of my polygons and lines to be sure they start above 17 and/or use the --polygon-size-limits option to filter out smaller pieces.
For now I can build a full Europe map including France and it still fits within the overview limits For the overview map levels I only use - motorway, trunk and primary (but not the motorway_link, trunk_link and primarylink) - for every level 12-14-15-16-17 I even use a different line code and line-width only because it just looks nice when zooming in - no tunnels, bridges, railways or oneway - Only waterways if the water-way relation is tagged longer dan 50km - Only residential landuse to highlight city area's - Only natural = * & area_size() > 2000000 (which is approximately 3km x 3km)
Since then, problems gone Kind regards Joris

Thank you !
Got the same levels and overview-levels as default style. levels = 0:24, 1:22, 2:20, 3:18 overview-levels = 4:17, 5:16, 6:15, 7:14, 8:12
How can I make overview lighter ? Supressing a level ? Decrease max-nodes with splitter ?

Hi Steph,
it seems your overview map contains too many details. Compare the options levels and overview-levels with the default style.

Hi,
Since a couple of days the compilation for my France map fails.
Perhaps the output log could help you to indicate me the direction I should investigate.

Style détaillé pour un usage pédestre mais fonctionnel aussi en usage cycliste ou motorisé.

Two little overlays (for ski resorts and particular osm tags I want to verify) are correctly produce. The main map compilation fails!
Regards.
Steph
