[Geoserver-users] Layer Grouping improvements

GeoServer GeoServer User
1

Hi guys,
I have here some code for a better management of layer-grouping option that I would like to share with the community.
The improvements are:

  • the possibility to add/remove any number of layer-groups
  • the possibility to insert an EPSG code and an Envelope ta a layer-group
  • the possibility to automatically generate the envelope of the layer-group
  • the layer-groups are listed into the WMS GetCapabilities and treated by GeoServer like other layers.

I would like to commit those changes into the 1.5.1 branch … my problem is that actually I really have no time to port the changes on other releases trunk, 1.6.x …

Let me know.

Cheers,
Alessio.

This functionality is great, and much needed IMHO - particulary if we can make elements of a layer group scale dependent.

I'm very concerned about committing any good stuff to a branch without keeping the trunk up to date though. I think there is no 1.6 as a separate branch - maybe ths makes it easier.

Hi Alessio,

Any chance we can get a bit more information. A couple of question?

1. Have you added a new configuration object called "LayerGroup"?
2. Is this a replacement for wmspath?

The reason I ask is because when I started to look at designing the
classes for a new config, I thought that Layer should be a first class
object, and Layer could be made up of other Layers, which would account
for grouping.

Hi Justin,
no, I haven’t added any new object, I use the same system as now. Layer groups are loaded into maps when loading the configuration, I just added the envelope info. About the WMS GetCapabilities I generate the metadata on the fly.

Having parent/child WMS layers would be great Justin - and cut down on the amount of configuration that needs to be done.

Cool, it would be nice if their were some patches to look over. Any
chance we get a look at the code before diving too deep into speculation .

Hi Justin,
sorry for the delay … sure, I can send you the patch and we can then discuss about that.

I get this occasion to say that I can’t attend the meeting tomorrow … however I’ll chek out the logs and reply.

I’ll send you the patch ASAP.

Thanks a ton. If you manage to post the patch, ok, otherwise you may consider opening a jira issue, improvement type, and attach the patch there.

I get this occasion to say that I can't attend the meeting tomorrow ... however I'll chek out the logs and reply.

Cool. Let's hope there will be a meeting, an logs to read (last week we
had no meeting at all) :slight_smile:
Cheers
