Re: [Geoserver-users] Problems with app-schema and srsName

[Ben Caradoc-Davies]

Gerhard,

I think that a better solution is to make the changes originally 
proposed by Victor:
https://osgeo-org.atlassian.net/browse/GEOT-3651

Victor and Jody, do you remember this one from 2011?

Jody, did you have some reservations about Victor's patch?

Kind regards,
Ben.

Hum... GeoServer uses JTS to put toghether the line segments into a long
line... normally it works,
when it does not, it's normally and indication that the lines are not
really touching each other,
which makes JTS unable to bring them toghether into a single long line.
Could that be your case?

Re: [Geoserver-users] Road number labeling difficulties

[Kanninen Anssi EXT]

Hi Andrea and thank you for the answer!

The screenshots are from Geoserver layer preview without any tiling enabled.
If I use grouping with repeating, it only shows the labels in the longest path.
If I add “labelAllGroups”, there’s too much of labels, too close to each other.

Best regards,
Anssi

Hi,
are there screenshots you're posting from a tiling client? 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.

Hello everybody and greetings from sunny Finland!

First of all, Geoserver is great! I'm amazed how fast it renders layergroups 
with almost 100 layers having different styles.

But I've got some difficulties when labeling roads and zooming the map out.
We've got some long roads with dozens of segments, all having the road number 
as an attribute.
I want the road number labels to be show along the long road with an equals 
distance from each other.

* When I zoom in with just two or three segments visible, the VendorOption 
"repeat" is enough. The labels are displayed nicely along the road 
(sample1.png).
* When I zoom out, I can not label all the segments anymore because the labels 
come too close to each other (sample2.png). So I will add VendorOption "group". 
But it only shows the labels in the longest path and not the labels on the 
other (possible slightly disjoint) segments (sample3.png).
* Then I add "labelAllGroup". But again, I get too much labels because every 
segment will have it (sample4.png).

(The example data is tiger_roads with only Broadway visible and an imaginary 
road number "R11" for all the segments.)

So, how can I display the labels along all the visible road segments, not too 
close or not too far away from each other?

Thank you!

Anssi Kanninen

docs.geoserver.org is usually a good option - better handled by search
