Hello everyone,
I've just started using Mapnik and I've already encountered some major problems.
I'm using Ubuntu 9.10 and during installations I generally followed steps from
OSM wiki (http://wiki.openstreetmap.org/wiki/Mapnik) .
Unfortunately, when I'm trying to use generate_tiles.py script, I can see
nothing but shorelines on my tiles and when zoom values are higher, I get
nothing but empty tiles.
Troubleshooting from wiki says:
"If the generated tiles or image show coastlines, but lack streets, street
names, cities, and other features, please verify that the database user can
indeed login. The scripts and Mapnik may quietly fail to read the data and thus
render with coastlines, but no other data. Another cause is building Mapnik
without PostGIS support."
But it doesn't give any clues how to fix the problem.
As far as I'm concerned, I am able to login to database (through psql -d gis -U
marcin, where "marcin" is my user name) and when I try \dt I get:
List of relations
Schema | Name | Type | Owner
--------+--------------------+-------+----------
public | geometry_columns | table | marcin
public | planet_osm_line | table | postgres
public | planet_osm_point | table | postgres
public | planet_osm_polygon | table | postgres
public | planet_osm_roads | table | postgres
public | spatial_ref_sys | table | marcin
(6 rows)
so database isn't empty also.
I've already tried setting non-empty password for my user (giving it to the
generate_xml.py script) and modifying trust settings in pg_hba.conf, but
nothing helped.
I would be grateful for any help.
Kind regards,
Marcin Waniek
