Re: [mapserver-users] WMS service problem with mapserver mapfile layer classes

[gorank]

Hi Jorg,
It works with you help. Thanks. Actually I had problem to show
municipalities in qgis but your suggestion to add YEAR in service url,
solves the problem. I use shapefile with Year as attribute name (time series
from 2009 to 2013) so in openlayers I select year from dropdown list and in
the map show values from the shossen column.

I would like from you confirmation url that you gave 
http://mapserver.stat.gov.mk/cgi-bin/GDZS/wms?map=/ms4w/apps/GDZS/NAS001_op.map&GODINA=2013&;

is final WMS url that users should have from our side, to access our WMS
service?

Goran

Re: [mapserver-users] color range fade to transparent.

[Rahkonen Jukka (MML)]

Hi,

Never tried myself but for sure nodata value is not the way because it is not 
any continuous measure, it is just on/off. And opacity setting affects the 
whole layer as Jörg wrote.

I believe that the right way is to include alpha channel to the output 
colorrange. There are examples in the kernel density document 
http://mapserver.org/development/rfc/ms-rfc-108.html. In this example I suppose 
that the output color is total blue for the whole range from 0 to 32 but alpha 
value is growing from 0 to 255.

style
COLORRANGE  "#ff00"  "#"
DATARANGE 0 32
end

I do not know how well and which clients support partial alpha values.

Hi Bob,

this cannot work I think. A colorrange from 255 0 0 to 254 254 254 renders a 
map with many colors. In  best case only data values at 300 will be rendered 
254 254 254 (perhaps you can check that with a color-picker? perhaps a clean 
254 254 254 is never reached).

But I think you would like to have a layer where the smallest value is not 
transparent, the highest value is totally transparent and the values between 
are a bit transparent, right? I think you only can set the opacity for the 
whole layer.

Hi Bob,

this cannot work I think. A colorrange from 255 0 0 to 254 254 254
renders a map with many colors. In  best case only data values at 300
will be rendered 254 254 254 (perhaps you can check that with a
color-picker? perhaps a clean 254 254 254 is never reached).

But I think you would like to have a layer where the smallest value is
not transparent, the highest value is totally transparent and the values
between are a bit transparent, right? I think you only can set the
opacity for the whole layer.

Re: [mapserver-users] WMS service problem with mapserver mapfile layer classes

Hi Goran,

problem solved? it seems to work...?

these two requests result in different maps:

What I don't understand is your classification. The validation only
allows 4-digit values and there's only one class that fits ( EXPRESSION
([%godina%] >= 20 and [%godina%] < 1)).

Or do you only wnat to know why your WMS does not work with qgis?
There you have to add your vendor parameter to the base url:
http://mapserver.stat.gov.mk/cgi-bin/GDZS/wms?map=/ms4w/apps/GDZS/NAS001_op.map&GODINA=2013&;

*AND* you have to check the option 'ingnore getMap-URI from
Capabilities' (or sth like that, don't know the english expression).
