About
OSMT (OSM Hybrid Carto) is a map style written in carto for OpenStreetMap data. It is designed as an overlay to be shown on top of satellite or aerial imagery.
I have a live demo of this map style here.

Configuration
You need to run ./configure.py first to configure osmt/osmt.mml with your
PostgreSQL connection parameters. Run ./configure.py --help for syntax.
After this you can compile the style sheet to a Mapnik2 XML style sheet using
carto osmt/osmt.mml > osmt.xml
You will also need to have some OSM data loaded into PostgreSQL using
osm2pgsql with the --hstore
option. A recent default.style
shipped with osm2pgsql should be sufficient.
Symbols
The contents of the symbols directory are referenced as /usr/share/icons/osmt/
in the style sheet.
The SJJB Map Icons referenced can be installed onto the system using the Debian package from http://anonscm.debian.org/gitweb/?p=pkg-osm/sjjb-map-icons.git or extracting the PNG package from http://www.sjjb.co.uk/mapicons/downloads into same system location.
Fonts
I encountered problems with fonts when using TileLite, TileCache and TileStache.
This is probably because the Debain build of Mapnik uses a font path of
/usr/share/fonts/truetype/ttf-dejavu. You can run mapnik-config --fonts to
check the current path. I found setting this to /usr/share/fonts/truetype
worked, either by changing this at Mapnik build time or by editing
/usr/share/pyshared/mapnik2/paths.py.
