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
