[Geoserver-users] Labels disappear when extended over several tiles

Hello,
I’m using GeoServer 2.3.1 with Oracle database, my problem is that my labels disappear when the text overlaps two tiles.

Do you know a solution that allows to truncate these texts at tiles border in order to make each text part on separate tiles.

Thanks for your help.

Best regards,
Kamardine

We would need a new vendor option in the text symbolizer to allow for
truncated label.
It's not there, but if you can develop in Java and are interested, I can
point you at the classes that would need to be modified

Hi Kamardine,

These labels disappearing are a typical result of tiling. The main approach to overcome this is to request larger images that would provide enough space for the offending labels to be drawn. In a next step, these meta tiles are sliced into smaller image tiles. GeoWebCache that comes with GeoServer nowadays does just that.

Maybe I am just stating the obvious here, so Andrea’s solution might still be valid and meta tiling is of no use in your case. Just thought I’d throw in this angle as well.

Best,

Edward
