GRAPHSERVER
OVERVIEW
Graphserver is a multi-modal trip planner. Graphserver supports transit modes
through GTFS, and street-based modes through OSM.
The core graphserver library has Python bindings which provide easy construction,
storage, and analysis of graph objects.

INSTALLATION
Prerequisites
Python 2.6+ (or 2.5+ for only graphserver.core)
Build
$ cd pygs
$ sudo python2.6 setup.py install
setup.py installs several executables. On debian these go into /usr/local/bin/.
On Mac OS X, these go into
/Library/Frameworks/Python.framework/Versions/2.6/bin/
Test a successful installation:
$ python2.6 -c "import graphserver.core; graphserver.core.Graph(); print 'Graphserver can be imported'"
Run the test harness (in verbose mode):
$ python2.6 setup.py nosetests -v
TOOLS
gs_gtfsdb_compile
Create a GTFSDatabase (sqlite3 db) from a GTFS zip file
$ gs_gtfsdb_compile google_transit.zip google_transit.gtfsdb
gs_osmdb_compile
Create a OSM database (sqlite3 db) from an OSM xml file
$ gs_osmdb_compile map.osm map.osmdb
gs_new
Create a new graph file
$ gs_new foobar.gdb
gs_import_osm
Import an OSM database to a graph file
$ gs_import_osm foobar.gdb map.osmdb
gs_import_gtfs
Import a GTFS database to a graph file
$ gs_import_gtfs foobar.gdb google_transit.gtfsdb
gs_link_osm_gtfs
Link OSM vertices to GTFS vertices to enable multimodal trip planning
$ gs_link_osm_gtfs foobar.gdb map.osmdb google_transit.gtfsdb
gs_osmfilter: run one of the filter classes from graphserver.ext.osm.osmfilters on an OSMDB instance
$ gs_osmfilter <Filter Name> <run, rerun, visualize> <osmdb_file> [<filter args> ...]
Building just the C .dll/.so
Provides the core DLL for routing. It is not necessary to manually build this if
using the Python bindings.
Build:
$ cd core
$ make
Install:
$ cd core
$ sudo make install
