Mapnik ignoring my lat long bounding box

Question

Can anyone see anything wrong with the following set of commands? Every time I run these image.png is a image of the UK and not the JOSM map I exported. I'm guessing there's something awry with the db import however the output mentions that it's processing my coords and data.

Steps:

1 - Exported a .osm file from JOSM or Merkaator.

2 - Imported into psql using the following command:

osm2pgsql -m -d gis -S ~/mapnik/default.style -b 103,1.3,104,1.4 ion.osm  -v -c

The output for this looks like:

    marshall@ubuntu:~/mapnik$ osm2pgsql -m -d gis -S ~/mapnik/default.style -b 103,1.3,104,1.4 ion.osm  -v -c
osm2pgsql SVN version 0.66-

I can see the correct lat/lon coords being passed in, I'm not sure how to verify this within the database

3 - ./generate_xml.py --accept-none --dbname gis --symbols ./symbols/ --world_boundaries ../world_boundaries/

4 - ./generate_image.py

At this point image.png is a map of the UK, not Singapore which I have specified.

Can anyone see anything wrong with this? This is with mapnik 0.71 on ubuntu

Answer 1

Found the solution.

The issue is that the generate_image.py script does not read the data from the database but rather has it hardcoded inside. I'm not sure the reasoning behind this.

The solution is to edit generate_image.py manually and change the relevant line:

ll = (103,1.3,104,1.4)
