Insert the data
 
Find the shortest path
 
To solve this example :doc:`pgr_dijkstra` is used:
 
To go from :math:`1` to :math:`5` the path goes thru the following vertices: :math:`1 \rightarrow 3 \rightarrow 6 \rightarrow 5`
 
Vertex information
 
To obtain the vertices information, use :doc:`pgr_extractVertices`
 
Graphs with geometries
 
Create a routing Database
 
The first step is to create a database and load pgRouting in the database.
 
Typically create a database for each project.
 
Once having the database to work in, load your data and build the routing application in that database.
 
Load Data
 
There are several ways to load your data into pgRouting.
 
Manually creating a database.

Using `osm2pgrouting <https://workshop.pgrouting.org/latest/en/basic/data.html>`__
 
There are various open source tools that can help, like:
 
shp2pgsql
 
postgresql shapefile loader
 
ogr2ogr
 
vector data conversion utility
 
osm2pgsql
 
load OSM data into postgresql
 
Please note that these tools will **not** import the data in a structure compatible with pgRouting and when this happens the topology needs to be adjusted.
 
Breakup a segments on each segment-segment intersection
 
When missing, add columns and assign values to ``source``, ``target``, ``cost``, ``reverse_cost``.
 
Connect a disconnected graph.
 
Create the complete graph topology
 
Create one or more graphs based on the application to be developed.
 
Create a contracted graph for the high speed roads
