[mapserver-users] using a SLD for a non-WMS layer.

[Martin Ouellet]

Hi all,

I would like a confirmation to be sure that I understand the process:

Considering that I can't use a sld directly inside a layer definition (in my
case BDTQ_HYDRO_L_ARC), I have to define another WMS layer
(BDTQ_HYDRO_L_ARC_SLD in my example below) that will be redirected to the
BDTQ_HYDRO_L_ARC layer WITH the  style definition file ("wms_sld_url") to
use for the rendering?

Currently, this process works very well but:
Q1: Is there a better way (or faster way for mapserver) for doing that
?(apply a sld to a non-WMS layer)?

Q2: What kind of degradation of performance can I expect with this cascading
workflow (2 time slower?)

Example:
    LAYER
        NAME "BDTQ_HYDRO_L_ARC"
        DATA "geom from bdtq_hydro_l_arc using srid=4269"
        TYPE LINE
MAXSCALEDENOM 150000
     MINSCALEDENOM 0
        METADATA
            "wms_name"             "BDTQ_HYDRO_L_ARC"
            "wms_title"                "Hydrographie Linéaire"
            "wms_keywordlist"     "TODO"
            "wms_abstract"          "TODO"
        END
        PROJECTION
            "init=epsg:4269"
        END
        CLASS
            STYLE
                COLOR 0 0 0
            END
        END
    END

    LAYER
        NAME "BDTQ_HYDRO_L_ARC_SLD"
        TYPE RASTER
        CONNECTION "http://<my server>/mapserv?map=bdtq"
        CONNECTIONTYPE WMS
        METADATA
            "wms_srs"                "EPSG:4269"

            "wms_server_version" "1.1.1"
            "wms_format"            "png"
            "wms_extent"            "-80 45 -54 60"
            "wms_sld_url"     "http://<my server>/sld/bdtq_hydro_l_arc.sld"
        END
    END
