If you are looking for more information on wireless networks, I have collected some general information on community wireless metropolitan area networks.
Some other wireless node registries:
The node data is stored in a MySQL database, and the web pages implemented with PHP.
The altitude data used by the database was jointly bought by David Leonard,
Kevin Fleming, Greg Canning and Norbie
from
Geo Mapping in mid-2001.
It consists of elevation samples accurate to 0.01m vertical,
spaced horizontally on a 9 second (approx 270m) grid.
The data sets are known as
AUSLIG 9 second DEM SG56 and SH56 if you're really interested.
(And we should be able to get more when they all become
free in 5-10 years.)
The altitude data is stored in huge unix files as a quadtree raster,
and manipulated and plotted with custom programs written in C, using
libpng.
UTM-to-curvilinear (easting/northing to lat/long) conversion uses equations from the AUSLIG GDA technical manual, and the ANS-GRS80 shift table data from NRM. Here are the instructions on finding your home's grid coordinates.
The topographic map data (coastline, roads etc.) comes from the ISCGM (via GA) and is rendered using some home-grown VPF plotting software and gd.
The hardware and operating system of the server are supplied by UQ ITEE, and manufactured by Sun Microsystems. The web server software is Apache.
All of the source code to the database scripts and mapping tools is available, if you are interested. Also, a generic database select form is available that you can use with XSL to construct your own web pages. Please see the copyright info.

The search utility is not a comprehensive search. It is intended as a convenience for jumping to a node if you know just a little info about it. However, it can help you to know how search works so you can understand its limitations.
First, the given search string has its whitespace replaced with SQL wildcard characters ('%'), and then LIKE-matches are done on the following fields in the database, in the given order: node name, contact name, comment text, street address/suburb. Only if the whole pattern is found in one of these fields is it displayed. At the head of the list are results that matches the node name; next those that matched contact name, and so on.
If only one match is found, you are redirected to the node's page immediately.
This database is a public service intended to let you find like-minded individuals in your part of Brisbane. What you and your peers send over your links is your business!
David Leonard and the University of Queensland accept no liability for the accuracy or content of this database. Inappropriate or offensive material will be removed.
