AW: [UMN_MAPSERVER-USERS] points variable substitution

[Arnd Wippermann]

Hello David,

I would think, you have to submit the coordinate in the projection, you will
use to display your map. I myself have only used the projection I have
defined on map level.

Second. This approach works only with a mapserver request. Perhaps your
example can be used with a WMS request (with vendor parameter lon and lat).

Arnd,

Thanks for the tip. I just tried this, but without success. Do annotations
like this permit projection?

Hello David,
 
via cgi you have also this way
 
&map_credits_feature=new
&map_credits_feature_points=2572146+5669256
&map_credits_feature_text=0566

&map_credits2_feature=new
&map_credits2_feature_points=10+588
&map_credits2_feature_text=yourText
&map_credits2_class_color=255+0+255

with this layers in the mapfile

#&map_credits_feature=new&map_credits_feature_points=2605395+5705380&map_cre
dits_feature_text=Hallo
LAYER
  NAME credits
  STATUS on
  TYPE ANNOTATION
  FEATURE
    #POINTS 104 396 END
    #TEXT '© GINFO'
  END
  CLASS
    COLOR 0 0 255
    OUTLINECOLOR 255 0 0
    SYMBOL 'circle'
    SIZE 10
    LABEL
      TYPE TRUETYPE
      FONT VERDANA
      SIZE 14
      #ANTIALIAS
      COLOR 0 0 0
      POSITION UR
      FORCE true
    END
  END
END

LAYER
  NAME credits2
  STATUS on
  TRANSFORM FALSE
  TYPE ANNOTATION
  FEATURE
    #POINTS 10 530 END
    #TEXT 'aa'
  END
  CLASS
    #OUTLINECOLOR 255 0 0
    COLOR 255 0 0
    SYMBOL 'Struktur'
    SIZE 9
    LABEL
      TYPE TRUETYPE
      FONT VERDANA
      SIZE 12
      #ANTIALIAS
      COLOR 0 0 0
      POSITION CR
      FORCE true
    END
  END
END

The difference between the first and second layer is the TRANSFORM
parameter. The credits text and circle will set at the defined coordinate,
the credits2 text and circle will drawn in the bottom left corner.

Should have done a bit more thinking and reading. A dummy OGR Connection
does the trick:

 

    CONNECTIONTYPE OGR

    CONNECTION '<OGRVRTDataSource>

                        <OGRVRTLayer name="Whatever">

 
<SrcDataSource>ODBC:Whatever/whatever at whatever</SrcDataSource>

                                    <SrcSQL>SELECT %lng% as Longitude, %lat%
as Latitude</SrcSQL>

                                    <GeometryType>wkbPoint</GeometryType>

                                    <LayerSRS>WGS84</LayerSRS>

                                    <GeometryField
encoding="PointFromColumns" x="Longitude" y="Latitude"/>

                        </OGRVRTLayer>

                        </OGRVRTDataSource>'

Subject: points variable substitution

 

I am wanting to plot one point as provided by a cgi query parameter for a
very simple application, but substituting something like POINTS -113 45 END
with POINTS %lng% %lat% END doesn’t work like I thought it would. Any
suggestions for how to pass a point via URL parameters (e.g.
&lng=-113&lat=45) & have it appear on a resultant map?

 

Thanks,
