[mapserver-users] LABELS - changing from single map to tiles and overlays - HOW?

[Worth Lutz]

I've now got labels on my maps when zoomed out but my polygons have no
labels if I zoom in away from the label location.

I'm using:

    PROCESSING "LABEL_NO_CLIP=True" 

Is this a fixable problem?

 

Are there any examples of getting labels with mapserver and openlayers using
tiles and multiple overlay layers?

 

I'm still experimenting but still confused.  Any help would be appreciated.

 

Thanks,

Worth

Donald,

 

How does the change to "TYPE POINT" work for polygon shapes or do you just
change that to "TYPE POLYGON" and only have a label in the "CLASS" block?

 

I'm still confused on how to manage labels on multiple overlay layers. That
may be a long term project for my application. I was hoping for a simple
solution.

 

I did figure out that putting

    PROCESSING "LABEL_NO_CLIP=True" 

in my layer fixed some of my problems of multiple labels with many clipped.

 

Thanks for your help,

Worth

Worth,

 

I have replaced "TYPE ANNOTATION" with "TYPE POINT" and all is working well.

 

As for tiling and labels, I have not found a satisfactory solution at all
and have accepted that I am getting partial labels or no labels it the label
starts in another tile - See here:
https://github.com/mapserver/mapserver/issues/4284

 

What I have done is offered an option of "Single Tile" for users so that
they can switch between tiled and not. The tiled option gives a better
OpenLayers slippy map experience but the single tile option allows for
accurate and complete labelling.

 

Regards,

 

Donald

Hi all,

 

I'm changing my usage of mapserver from a single map image to using
OpenLayers and having MapServer work as a WMS server.

 

My problem is labels. There seem to be too many variables (in MapServer and
OpenLayers) and I cannot figure out which to set to keep from having partial
labels, too many labels or overlapping labels.

 

What is the best way to approach labels in a tiled / overlay environment.

 

I noticed that in MapServer 6.0 the "annotation" layer type is deprecated.
What is the method for replacing this?

 

In summary, I'm LOST.  Anyone with a map, please point me in the right
direction. :-)

 

Thanks,

Worth
