[mapserver-users] Basemap as merged and separate layers

[Rahkonen Jukka (MML)]

Hi,

I believe (hope) that it is possible, perhaps by leaving the  names of the layers in the group empty, or with wms_enable_request metadata. Some links which seem relevant:

https://mapserver.gis.umn.edu/development/rfc/ms-rfc-67.html
https://github.com/mapserver/mapserver/issues/5404
https://github.com/MapServer/MapServer/pull/5533

Hello,

I think some part of your need can be done in MapServer, look at the wms_layer_group layer metadata in https://www.mapserver.org/ogc/wms_server.html. but all LAYERs will be always shown in MapServer.

Hi

I have a basemap in Mapserver 7.4.3 presented as a WMS-layer.

As many maps it consists of landusage, roads, label and so on.
Each of these "layers" or parts of the map consist of many <layer> in the mapfile for different scales.
For example land0, land1.... and roads0, roads1 and so on. Much like https://mapserver.org/basemaps/index.html

Currently all layers are part of "GROUP default" and map renders correctly when asking for LAYERS=default.

Unfortunately all layers (land0,land1,roads0,road1...) are also show in the Capability.

What I would like have is instead a response in the capability where there are layers for "the main map" and also a grouped layer for all "zoom layers" i.e. roads0,roads1 combined to a roads layer.
For example the layers default, land and roads should be the only layers visible in the Capability and possible to render in a GetMap-request.
A GetMap request for LAYERS=roads should show all the separate roads* layers only.

Can this be done in Mapserver?

Thanks,
Jesper
