[mapserver-users] Cut off/missing tiles [bump]
Hi I have an issue which seems to relate to tile-edge buffering and world-view zoom levels. There's an example page at http://mapserver.magicsite.co.uk When you first visit the page, all seems normal, until you zoom out 1 level, at which point the tile which should sit over the west of the US doesn't display. From what I can see, when tile-edge buffering is ON and the tile next tile wraps around the world, the tile in question is not rendered. Turn edge-buffering off and that tile is rendered correctly. Unfortunately, I'm in a position where I can't turn the buffering off. from the mapfile: WEB METADATA wms_title wms_onlineresource wms_srs EPSG:4326 tile_map_edge_buffer 9 # 9 pixel rendering buffer http_max_age 86400 END END As far as I can tell, everything else is working correctly. What I'm not clear on - is this a bug in the edge buffering within the software, or am I doing something wrong? The server running the example URL is currently using version 5.7-dev, but the same issue is also apparent on a production server running v6.0.2 Interested to know if anyone else has experienced the same issue?

Re: [mapserver-users] Cut off/missing tiles [bump]
Try adding +over to your epsg definition of 4326. It fixed the problem for me. Mine looks like this now: /usr/local/share/proj/epsg 4326 +proj=longlat +ellps=WGS84 +datum=WGS84 +over +no_defs You might need to upgrade your version of PROJ4 for it to have an effect.
