PointSymbolizer Aggregation

[garraud.alexandre]

Hello all,

I have a problem with a representation of my points. My points seems to
be aggregated at larger scale. I can see only one feature where several
feature exists.

My layer :
<Layer name="port" srs="+init=epsg:4326" status="on">
    <StyleName>style_node_port</StyleName>
    <Datasource>
         <Parameter name="type">postgis</Parameter>
         <Parameter name="host">&db_host;</Parameter>
         <Parameter name="port">&db_port;</Parameter>
         <Parameter name="user">&db_user;</Parameter>
         <Parameter name="password">&db_password;</Parameter>
         <Parameter name="dbname">&db_name;</Parameter>
         <Parameter name="table">(select * from node where type = 1) as
node</Parameter>
         <Parameter name="estimate_extent">false</Parameter>
         <Parameter name="extent">-180,-90,180,90</Parameter>
         <Parameter name="encoding">utf8</Parameter>
    </Datasource>
</Layer>
<Style name="style_node_port">
    <Rule>
       <Filter>[type] = 1</Filter>
       <PointSymbolizer file="&image_dir;/port.png" width="16"
height="16" type="png"></PointSymbolizer>
    </Rule>
</Style>

My result:
only 2 points / 6 => Capture-1.png
all points => Capture-2.png

If someone has an idea ?

Alexandre

Try adding allow_overlap="1" to PointSymbolizer.

No, it is for PointSymbolizer :

<PointSymbolizer allow_overlap="yes" file="/Users/artem/projects/
openstreetmap/mapnik/symbols/station_small.png" type="png" width="5"  
height="5" />







<PointSymbolizer allow_overlap="no" file="/Users/artem/projects/
openstreetmap/mapnik/symbols/station_small.png" type="png" width="5"  
height="5" />







Are you using latest mapnik ?

Cheers
Artem

Hi

I have a similar Problem with Overlapping Point Symbols. Can I also include
the overlap clause in Python?

sym = PointSymbolizer("/tmp/pub.png", "png", 16, 16)

How and where?


Thanx
Ryo09

Ryo09,

'allow_overlap' and 'opacity' are optional parameters of the  
PointSymbolizer and therefore are available as attributes that can be  
get or set after you've created the object.

See: http://trac.mapnik.org/wiki/PointSymbolizer?version=12#Python1
