## INTRODUCTION
pgRouting is a network routing extension for PostgreSQL that works with PostGIS
This package is for PostGIS 2.0,2.1,2.2,2.3
More details can be found at: http://pgrouting.org/

pgRouting extends the PostGIS/PostgreSQL geospatial database to provide geospatial routing and other network analysis functionality.

This 2.2 library contains following features:

    All Pairs Shortest Path, Johnson Algorithm (new 2.0)
    All Pairs Shortest Path, Floyd-Warshall Algorithm (new 2.0)
    Shortest Path A*
    Bi-directional Dijkstra Shortest Path (new 2.0)
    Bi-directional A* Shortest Path (new 2.0)
    Shortest Path Dijkstra
    Driving Distance
    K-Shortest Path, Multiple Alternative Paths (new 2.0)
    K-Dijkstra, One to Many Shortest Path (new 2.0)
    Traveling Sales Person (enhanced 2.0)
    Turn Restriction Shortest Path (TRSP) (new 2.0)
	
	Changes since 2.1
	
    Improved:
        pgr_nodeNetwork
            Adding a row_where and outall optional parameters

    Signature fix
        pgr_dijkstra -- to match what was documented (the pgr_dijkstra from V2.0)

    New functions
        pgr_floydWarshall
        pgr_Johnson
        pgr_DijkstraCost

    New Proposed functions
        pgr_withPoints
        pgr_withPointsCost
        pgr_withPointsDD
        pgr_withPointsKSP
        pgr_dijkstraVia

    Deprecated functions:
        pgr_apspWarshall use pgr_floydWarshall instead
        pgr_apspJohnson use pgr_Johnson instead
        pgr_kDijkstraCost use pgr_dijkstraCost instead
        pgr_kDijkstraPath use pgr_dijkstra instead


## INSTALL
To install first create a postgresql database using createdb, psql, or pgAdmin
Copy the files from this zip file to same named folders in your PostgreSQL install.

Install PostGIS 2.1 or 2.2 using:
CREATE EXTENSION postgis;

If you have multiple versions of PostGIS and want to force a particular version do:
--For latest stable
CREATE EXTENSION postgis VERSION "2.2.2";

--For latest dev
CREATE EXTENSION postgis VERSION "2.3.0dev";

Then install pgRouting:

CREATE EXTENSION pgrouting;


If updating from old pgrouting use instead
ALTER EXTENSION pgrouting UPDATE;
