<title>Address Standardizer</title>

<para>This is a fork of the <ulink url="http://www.pagcgeo.org/docs/html/pagc-11.html">PAGC standardizer</ulink> (original code for this portion was <ulink url="http://sourceforge.net/p/pagc/code/360/tree/branches/sew-refactor/postgresql">PAGC PostgreSQL Address Standardizer</ulink>). </para>
|
|
<para>The address standardizer is a single line address parser that takes an input address and normalizes it based on a set of rules stored in a table and helper lex and gaz tables.</para>
|
|
<para>The code is built into a single postgresql extension library called <code>address_standardizer</code> which can be installed with <code>CREATE EXTENSION address_standardizer;</code>. In addition to the address_standardizer extension, a sample data extension called <code>address_standardizer_data_us</code> extensions is built, which contains gaz, lex, and rules tables for US data. This extensions can be installed via: <code>CREATE EXTENSION address_standardizer_data_us;</code></para>
|
|
<para>The code for this extension can be found in the PostGIS <filename>extensions/address_standardizer</filename> and is currently self-contained.</para>
|
|
<para>For installation instructions refer to: <xref linkend="installing_pagc_address_standardizer" />.</para>

|
<sect1 id="Address_Standardizer_Basics"><title>How the Parser Works</title>
|
|
<para>The parser works from right to left looking first at the macro elements
|
|
for postcode, state/province, city, and then looks micro elements to determine
|
|
if we are dealing with a house number street or intersection or landmark.
|
|
It currently does not look for a country code or name, but that could be
|
|
introduced in the future.</para>
