This tool provides an OpenStreetMap data parser to turn them into a nodes-edges
2+
adapted for routing applications.
3+
4+
== INPUT FORMAT ==
5+
The input is an OpenStreetMap XML file. The file can be read:
6+
* from a plain .osm file
7+
* from a bz2 file
8+
* from stdin
9+
10+
== OUTPUT FORMAT ==
11+
The output can be:
12+
* a csv file
13+
* postgis database (geographical extension to postgres).
14+
15+
In both output you'll get two files/tables:
16+
* nodes that contain
17+
* id (64 bit integer)
18+
* longitude (decimal real)
19+
* latitude (decimal real)
20+
21+
* edges that contain
22+
* id (64 bit integer)
23+
* source node id (64 bit integer)
24+
* target node id (64 bit integer)
25+
* length (real in meters),
26+
* car accessibility (integer)
27+
* car reverse accessibility (integer)
28+
* bike accessibility (integer)
29+
* bike reverse accessibility (integer)
30+
* foot accessibility (integer)
31+
* geometry (string representing a linestring in the WKT format)
32+
33+
The accessibility is an integer describing the edge for every mean of transport.
34+
As for cars an bikes the driving direction might change those properties, the
35+
are direct (source->target direction) an reverse (target->source direction)
36+
information.
37+
38+
The integers mean:
39+
* cars
40+
* 0 forbiden
41+
* 1 residential street
42+
* 2 tertiary road
43+
* 3 secondary road
44+
* 4 primary road
45+
* 5 trunk
46+
* 6 motorway
47+
* bike
48+
* 0 forbiden
49+
* 1 cycling lane in the opposite direction of the car flow
50+
* 2 allowed without specific equipment
51+
* 3 cycling lane
52+
* 4 bus lane allowed for cycles
53+
* 5 cycling track
54+
* foot (no distinction in made on the direction)
55+
* 0 forbiden
56+
* 1 allowed
57+
58+
59+
== INSTALL ==
60+
You need:
61+
* the GCC C++ complier (g++)
62+
* Boost
63+
* expat (XML parser)
64+
* libbz2 (Bzip2)
65+
* libpq (postgres)
66+
67+
Run make and it should compile.
68+
69+
70+
== USAGE ==
71+
Get the .osm XML file of the region that interests you.
72+
For limited regions, use the export tools from the web interface.
73+
For bigger regions you might find what you want at http://download.geofabrik.de/osm/
74+
75+
To know the options, run:
76+
./osm4routing --help
77+
78+
79+
== Postgres output ==
80+
The database must be a postgis database.
81+
The usual way to get is to execute the following commands (the location of
82+
lwpostgis.sql and spatial_ref_sys.sql depend on your installation).
83+
84+
createdb yourdatabase
85+
createlang plpgsql yourdatabase
86+
psql -d yourdatabase -f lwpostgis.sql
87+
psql -d yourdatabase -f spatial_ref_sys.sql
