Hi,
I'm working on a custom xml to work with a navteq dataset. But I'm already
struggling with getting any kind of data visualized by rendering with
mapnik2.
my Layer specification looks like this:
<Layer name="myLayer" status="on" srs="+init=epsg:4326">
<StyleName>myLayer_style</StyleName>
<Datasource>
<Parameter name="table">
(select the_geom, 'true' as "water", polygon_nm as "name"
from waterseg )
as myLayer
</Parameter>
<!--
Settings for your postgres setup.
Note: feel free to leave password, host, port, or use blank
-->
<Parameter name="type">postgis</Parameter>
<Parameter name="password"/>
<Parameter name="host"/>
<Parameter name="port"/>
<Parameter name="user">postgres</Parameter>
<Parameter name="dbname">navteq_static</Parameter>
<!-- this should be 'false' if you are manually providing the 'extent' -->
<Parameter name="estimate_extent">false</Parameter>
<!-- manually provided extent in epsg 900913 for whole globe -->
<!-- providing this speeds up Mapnik database queries -->
<!-- <Parameter
name="extent">-20037508,-19929239,20037508,19929239</Parameter> -->
<Parameter name="extent">5.95, 45.86, 10.48, 47.75</Parameter>
</Datasource>
</Layer>
and the stylesheet is very simple. I'd like to see anykind of result before
messing around with the parameters!
<Style name="myLayer_style">
<Rule>
<Filter>[water]='true'</Filter>
<MaxScaleDenominator>250000000000</MaxScaleDenominator>
<MinScaleDenominator>2500</MinScaleDenominator>
<LineSymbolizer stroke="#b5d0d0" stroke-width="5.0"/></Rule>
</Style>
My geometries are in EPSG:4326
Thank you!
Martin
