[MapServer-users] mapserver union layer of type chart
Hello,
just wondering weather it is possible to have union (by connectiontype) layer
of type chart?
Yesterday I have tried, but each time got an empty image.
Configuration looks like:
LAYER
NAME union_layer_name
TYPE CHART
#PROCESSING "CHART_TYPE=pie"
#PROCESSING "CHART_SIZE_RANGE=c 30 100 2 200 5"
PROCESSING "ITEMS=province,c,n,y,ts,level_code"
STYLEITEM "AUTO"
STATUS DEFAULT
CONNECTIONTYPE UNION
CONNECTION "layer1,layer2 etc."
METADATA
ows_title "name"
ows_include_items '*'
gml_include_items "all"
gml_geom_type "point"
ows_enable_request '*'
"wms_timeextent"
"2009,2010,2011,2012,2013,2014,2015,2016,2017,2018,2019,2020,2021,2022,2023"
"wms_timeitem" "ts"
"wms_timedefault" "2009"
END
PROJECTION
"init=epsg:4326"
END
VALIDATION
'time' '[0-9]{4}'
'default_time' '2009'
END
CLASS
END
END
LAYER
NAME layer1
CONNECTIONTYPE POSTGIS
CONNECTION "host=x dbname=x user=x password=x"
DATA "geom_p from (... ) foo using unique province using srid=4326"
STATUS ON
TYPE CHART
PROCESSING "CHART_TYPE=pie"
PROCESSING "CHART_SIZE_RANGE=c 30 100 2 200 5"
STATUS ON
PROCESSING "LABEL_NO_CLIP=True"
PROJECTION
"init=epsg:4326"
END
VALIDATION
'time' '[0-9]{4}'
'default_time' '2009'
END
METADATA
wms_title "layer 1"
gml_include_items "all"
gml_geom_type "point"
ows_include_items "all"
ows_enable_request "*"
"wms_timeextent"
"2009,2010,2011,2012,2013,2014,2015,2016,2017,2018,2019,2020,2021,2022,2023"
"wms_timeitem" "ts"
"wms_timedefault" "2009"
END
MAXSCALEDENOM 1001
MINSCALEDENOM 121
FILTER ([level_code]=1)
etc...
If I uncomment these lines in union layer:
#PROCESSING "CHART_TYPE=pie"
#PROCESSING "CHART_SIZE_RANGE=c 30 100 2 200 5"
This works but returns an empty image. And if these lines are not there ,
mapserver breaks with internal error.
I have looked briefly through documentation but nowhere was mentioned that
union layer doesn’t support type chart, so maybe there is something missing in
my mapfile.
Another thing is that may be there are other better option for me rather than
using union layer. The thing is that I would like to draw map charts for
different administrative units based on map scales, let’s say if I am in small
map scale to draw chart for the country, if I zoom in — for district, and if I
zoom further — for municipality. I have tried to keep it all in one layer of
type chart and use this type of class definitions:
class
expression ([level_code]=1)
minscaledenom 100
maxscaledenom 50
…..
But it didn’t work — apparently in layer of type chart keyword expression is
not used in the same way as in other layers.
So, would be grateful if someone could help me with this.
Sincerely, Zmitser

Re: [mapserver-users] data parameter in tileindex
Thank you very much, Edward, for the suggestion. But I use tiles of vector data. And currently the problem is how to put postgis connection and data parameter in one (so that mapserver parses it correctly from location column of tileindex) .

Re: [mapserver-users] data parameter in tileindex
Dear Jukka, you right with OGR it works. If I type something like: "PG:"dbname=database host=127.0.0.1 port=5432 user=admin password=admin tables=objects_in_countryA(geom)"" It works. Because for OGR layer types, providing connection is enough. But for PostGIS , also the data part need to be provided separately. In fact , it is just a matter of interest for me. What will be faster , have it with OGR PostGIS driver or with native mapserver postgis driver (I assume if type of connection PostGIS mapserver uses its own driver for reading features). I will let you know after I find out the way.

Re: [mapserver-users] data parameter in tileindex
Dear Carlos, it is not about mapfile, it is in location cell of tileindex. It is one cell in table (database table, dbf file etc.), and I need to put there both connection and data details. The question is how to make it so that mapserver parses it correctly.

[mapserver-users] data parameter in tileindex
Dear mapserver users, I need to specify data parameter at the location item of tileindex. So far, I have tried many possibilities but none works: ‘host=127.0.0.1 dbname=database user=admin password=admin DATA "geom from table using unique id using srid=4326"’ or host=127.0.0.1 dbname=database user=admin password=admin data="geom from table using unique id using srid=4326" etc. Still I get an error : msDrawMap(): Image handling error. Failed to draw layer named 'layer'. msPostGISLayerOpen(): Query error. Nothing specified in DATA statement. Could someone please tell in which format data statement should be? In documentation it is written vaguely: Normally the location should contain the path to the tile file relative to the shapepath, not relative to the tileindex itself. If the DATA parameter contains a value then it is added to the end of the location. -- Zmitser Kozhukh___ mapserver-users mailing list mapserver-users@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/mapserver-users
