Have you tried a larger edge buffer? I suppose that’s tough to to test given the randomness. I’ll check my settings on a similar setup when I’m in the office tomorrow and let you know. It would be interesting to see the corresponding metatile to see if the label is whole there. I wouldn’t think so but having a reproducible test case would help immensely.
Anyone know how to compute a metatile URL for a given tile x/y/z? —Steve On Mon, Oct 31, 2022 at 10:16 AM Thomas Ellett von Brasch < thomas.ell...@kartverket.no> wrote: > Hi all, > > > > I'm really struggling to fix a longstanding issue with clipped labels in a > couple of our wmts services. > > I've tried following the mapserver/mapcache docs and numerous variations > of different attributes, but with no luck. > > > > The main problem bug fixing is that the issue seems to be quite random, > just popping up here and there. > > > > Examples can be seen in these urls: > > > > > https://norgeskart.no/#!?project=norgeskart&layers=1002&zoom=11&lat=6879652.31&lon=167744.51 > > > > (the 'Stor rar' and 'S' names in the centre of the map) > > > > > https://norgeskart.no/#!?project=norgeskart&layers=1002&zoom=6&lat=6440416.41&lon=127931.07 > > > > ('Kristiansan' , which should be 'Kristiansand') > > > > I have "labelcache_map_edge_buffer" "10" in the mapfile and > <metabuffer>10</metabuffer> set in the mapcache file. > > > > In the source WMS, the placenames layers are line layers (with very small > line geometries used just to give curved lines) and the layers (we have > several name layers for the different zoom levels, but they're all set up > in the same way) look like (truncated): > > > > LAYER > > NAME "N100Stedsnavn" > > PROCESSING "CLOSE_CONNECTION=DEFER" > > PROCESSING "LABEL_NO_CLIP=True" > > TYPE LINE > > > > CLASS > > NAME "N100 Stedsnavn" > > EXPRESSION ([fmx_rotation] != 0) > > LABEL > > *PARTIALS FALSE* > > *ANGLE follow* > > ANTIALIAS TRUE > > FONT "verdana" > > SIZE [fontsize] > > COLOR [geodb_color] > > ENCODING "UTF-8" > > PRIORITY [fontsize] > > *FORCE FALSE* > > MINDISTANCE 50 > > OUTLINECOLOR 254 254 254 > > POSITION [horizontalalignment] > > TYPE TRUETYPE > > END > > TEXT "[textstring]" > > END > > END > > > > And the tileset definition in the mapcache config file looks like: > > > > <tileset name="norgeskart_bakgrunn"> > > <source>norgeskart_bakgrunn</source> > > <cache>norgeskart_bakgrunn</cache> > > <metadata> > > <title>Topografisk Norgeskart og dybdedata og svalbard minus > matrikkel</title> > > <abstract>Cache for Norgeskart</abstract> > > </metadata> > > <grid>googlemaps</grid> > > <grid>utm33n</grid> > > <format>PNG</format> > > *<metatile>8 8</metatile>* > > *<metabuffer>10</metabuffer>* > > </tileset> > > > > Is it possible the metatiles being used in the original seed job and later > seeding jobs are different somehow? > > > > Given that the labelcache_map_edge_buffer is set (along with metabuffer) > and we have PARTIALS FALSE in the mapfile, I didn't think that cut labels > would be possible? > > > > Any thoughts or ideas would be great J > > > > Thanks in advance! > > > > Tom > > > > > > [image: cid:image001.jpg@01D3A415.20CB4FE0] > > *Tom Ellett von Brasch* > Sjefsingeniør > *Geodatatjenester* > > Direkte: 32 11 84 73 > > Mobil: 45806402 > > E-post: thomas.ell...@kartverket.no > > > Tlf. sentralbord: 32 11 80 00 > www.kartverket.no > > > > > _______________________________________________ > MapServer-users mailing list > MapServer-users@lists.osgeo.org > https://lists.osgeo.org/mailman/listinfo/mapserver-users >
