[postgis-users] Maps and geocoding for Australia

[Stephen Woodbridge]

Hi all,

Apologies for the cross posting.

Over the past month or so I have been playing with OpenData for 
Australia. This is a work in progress, but I thought some of you might 
be interested.

## Maps
http://imaptools.com:8080/demo/australia.html

    394 australia-10m-map.inc
   3663 australia-250k-map.inc
    423 australia-2.5m-map.inc
    190 australia.map
    705 etc/symbols.txt
   5375 total

I want to revist the mapfile at some point and build a non-topo version 
with simplifed styling. The mapfile is ready for use with mapcache and 
I'll enable that at some point, but at the moment its draw on demand. It 
took a lot of work to get the Topo map styled to their standards. 
Unfortunately they do not yet offer the detailed street layer data, so 
when you zoom in you will see green dots representing the GNAF address 
file geocode points.

## Reverse Geocoding
click on the map and it geocodes the lat/lon into a popup.

## Geocoder
http://imaptools.com:8080/demo/imt-geo-australia.php

The geocoder is also integrated into the map, enter the address and 
click [Go]. The geocoder is built on a modified version of the postgis 
address_standardizer2 extension. I'll be checking in the remaining 
changes into postgis when I have a chance. The latest and greatest is 
always located here [1]. I have added a couple of diagnostic tools to 
help understand how the address standardizer is working and to make it 
easier to evaluate how to make changes to the lexicon and grammar as you 
develop them for a specific data set. The address standardizer comes 
with sample lexicon and grammar data for about 20 countries.

If anyone has some time and interest, I would love to get a C++ 
developer to code review the address standardizer, especially with an 
eye toward improving performance.

If you have questions, feel free to contact me on/off list.
