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

[Worth Lutz]

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
