Hi Daniel,
It seems I haven't got the right osm data, I used to download the follow
data:
wget
http://downloads.cloudmade.com/oceania/australia_and_new_zealand/new_zealand/new_zealand.osm.administrative.bz2
wget
http://downloads.cloudmade.com/oceania/australia_and_new_zealand/new_zealand/new_zealand.osm.bz2
wget
http://downloads.cloudmade.com/oceania/australia_and_new_zealand/new_zealand/new_zealand.osm.coastline.bz2
wget
http://downloads.cloudmade.com/oceania/australia_and_new_zealand/new_zealand/new_zealand.osm.highway.bz2
Which don't have the mentioned admin boundaries. I changed to another
dataset:
wget http://downloads.cloudmade.com/oceania/oceania.osm.bz2
and the boundaries turned out.
I still got the error message:
proj_init_error:failed to initialize projection with:+init=epsg:4326
I simply commented the following two layers to get around:
<Layer name="necountries" srs="+init=epsg:4326">
<StyleName>necountries</StyleName>
<Datasource>
<Parameter
name="file">/home/postgres/osm/mapnik/world_boundaries/110m_admin_0_boundary_lines_land.shp</Parameter>
<Parameter name="type">shape</Parameter>
</Datasource>
</Layer>
<Layer name="nepopulated" srs="+init=epsg:4326">
<StyleName>nepopulated</StyleName>
<Datasource>
<Parameter name="encoding">latin1</Parameter>
<Parameter
name="file">/home/postgres/osm/mapnik/world_boundaries/10m_populated_places.shp</Parameter>
<Parameter name="type">shape</Parameter>
</Datasource>
</Layer>
Is this caused by proj4? I have installed proj.x86_64 4.7.0-3.fc14.
Thanks a lot,
Sige
