[Geoserver-users] Label fit problem when followLine=on
Hi! Is there any way to render a label with followLine=on if the label doesn't fit on the line (the line is too short for the whole label) ? A fallback to followLine=off would be a nice feature in this case. Cheers! - Anssi -- Attend Shape: An AT Tech Expo July 15-16.

Re: [Geoserver-users] Road number labeling difficulties
I think my problem could be solved by minGroupDistance but that option doesn’t seem to do anything in Geoserver 2.9.0.

There may indeed be some discontinuation between the segments but what would that change? I still want the labels have an equal space between them. It would allow the JTS LineMerge algorithm to create one single large line, that is then labelled according to the other directives (repeate) The example data in my screenshots is the example data provided by Geoserver so I assume it is be valid. Err... that data has been heavily simplified to keep the size of the download small, so I would not count on it being valid. That said, I re-read your first mail properly (10pm saturday night, I'm not in a rush like in a usual work day) and took the time to actually setup the style on a demo server: http://demo.geo-solutions.it/geoserver/tiger/wms?service=WMS=1.1.0=GetMap=tiger:tiger_roads=r11=-74.02722,40.684221,-73.907005,40.878178=476=768=EPSG:4326=application/openlayers#toggle At least in some parts the data is actually disconnected, or otherwise not forming a single line, e.g.: http://demo.geo-solutions.it/geoserver/tiger/wms?SERVICE=WMS=1.1.1=GetMap=image%2Fpng=true=r11=tiger%3Atiger_roads=EPSG%3A4326=1600=768=-73.99920701980591%2C40.75648784637451%2C-73.96487474441528%2C40.77296733856201 http://demo.geo-solutions.it/geoserver/tiger/wms?SERVICE=WMS=1.1.1=GetMap=image%2Fpng=true=r11=tiger%3Atiger_roads=EPSG%3A4326=950=600=-73.9958381652832%2C40.73277711868286%2C-73.98564577102661%2C40.7392144203186 http://demo.geo-solutions.it/geoserver/tiger/wms?SERVICE=WMS=1.1.1=GetMap=image%2Fpng=true=r11=tiger%3Atiger_roads=EPSG%3A4326=950=600=-74.01639461517334%2C40.70351421833038%2C-74.01129841804504%2C40.706732869148254 In other cases however it might a numeric issue, since by the time the labeller gets the lines they have been generalized and transformed to screen space, but with different roundings (what was touching before might not be exactly touching after). I did not investigate further, but there might be room for improvement there... I'm not sure it's going to be a quick fix however, I guess we'd have to round all ordinates to the nearest pixel before trying to attempt the LineMerge. That said, it's speculation, might be something else. Cheers Andrea -- == GeoServer Professional Services from the experts! Visit http://goo.gl/it488V for more information. == Ing.

Does the labeling work fine if you look at the GeoServer layer preview without tiling enabled? The solution should be group, group all with an eventual repeat, but if you are tiling there is one labelling run per tile, the system is not aware of what happens in the nearby tiles. The minGroupDistance option is still there and I see it used in the code.
