Hello list
Wondering if anyone can help…
We have been utilising the legendicon mode to create a custom legend in our
application, however some recent work to try and speed up our WMS has reworked
our mapfiles slightly, making use of GROUP LAYERs to group almost identical
LAYERs together, the only difference in the LAYERs being MAX & MINSCALEDENOM
and the DATA request string to our PostGIS database – hitting a generalised
version of the geometry at smaller scales.
LAYER
NAME 'lri_luc_main_gen_500k'
GROUP 'lri_luc_main'
DATA 'the_geom_gen_500k FROM "data"."lri" USING UNIQUE gid
USING srid=2193'
INCLUDE 'includes/lri_luc_main_layer.inc'
MINSCALEDENOM 251001
END
LAYER
NAME 'lri_luc_main_full'
GROUP 'lri_luc_main'
DATA 'the_geom FROM "data"."lri" USING UNIQUE gid USING
srid=2193'
INCLUDE 'includes/lri_luc_main_layer.inc'
MAXSCALEDENOM 251000
MINSCALEDENOM 15000
END
The request for the legend icon is of the form:
http://<servername>/cgi-bin/mapserv.fcgi?FORMAT=image/gif&MAP=lri.map&MODE=legendicon&ICON=lri_luc_main,1
This worked fine before we started using GROUPs, however now we now encounter
the error:
mapserv(): Web application error. Icon layer=lri_luc_main not found in map file.
Does the legendicon mode work with GROUP layers?
If not, is there a way round this?
Or alternatively, perhaps there is a better way to request a generalised
version of the geometry that doesn't involve GROUP LAYERs?
Any help or suggestions much appreciated.
Many thanks
Andrew
