Netstumbler tells you were the Wi-Fi access points are at. WPS tells
you where you are at based on signals from Wi-Fi access points.
WPS doesn't care what the SSID is. It detects Wi-Fi systems
regardless of if they are broadcasting their SSID and records the MAC
address, which rarely changes.
Yes, Wi-Fi is changing and will require the area to be redriven at a later
date.
I rarely ever, am unable to detect a Wi-Fi signal with the scanning
device that I'm using.

Subject: [aprssig] findU status
Thanks to Dave, KG4YZY, the findU primary server is in its new home. At
this time, I believe I have everything fully functional on both servers.
The name www.findu.com is loadsharing between both. If you see anything not
working, try with both www1.findu.com and www2.findu.com, and notify me of
the URL which has the the problem.
Thanks for your patience through this trying time...

I noticed that some of the maps that were coming to my web page directly
from aprsworld.net had stopped working because I think there was something
wrong with Jame's server, but it looked as though the findu street maps
supplied via aprsworld were working. Are the FINDU maps from aprsworld
actually OK or am I just not looking for the right thing. I would guess
that you have a different source to get maps from his server than what the
general public uses.

Having lived in Arizona/Phoenix for 14 years I would not recommend leaving
any electronics in your vehicle. Not because of the heat, but because it
will be gone, leaving you with nothing but a smashed window or two.
BioSphere 2 is fun to look at, but the concept will NEVER work. Land-based
plants do not produce a net surplus of oxygen, nor can you stock 3.5 acres
with enough biodiversity to provide real food for a human. While the
Biospherians ate capsicum peppers for their vitamin content, most people
would develop cancer after doing that for more than a year or two. It took
something like 50,000 gallons of sodium hydroxide to scrub the air of CO2
in the BioSphere. And that wasn't enough.
Moon and mars on the horizon for what? 17% and 38% of the Earth's gravity
respectively. No atmosphere, no water, not enough gravity. The
atmosphere of Mars is 6 millibars of mostly CO2, the earth 1013 millibars
(at sea level) of air. Water cannot exist on the surface of Mars, even in
ice form it would sublimate. Humans treveling to Mars would probably
never be able to return to Earth due to bone calcium loss.
Regards,
Mark

I'm not sure what James' server situation is currently, the domain I use is
geo.aprsworld.net, which supplies the map and a geo file so my server can
draw in the appropriate place. This could be a separate server or a virtual
domain (for example, as www.aprs.net and www.findu.com, and dozens of
others, are served on my two machines).

Netstumbler will listen to a GPS and has scripts (have to search the web
for them) that will use Microsoft Mappoint and plot all the points on a map
as you drive.. As you get closer to a access point, it will move the point
on the map to the location where the signal gets higher, pinpointing its
location. Save the map in mappoint and you got a whole map of access
points.

Maybe I'm missing something. Netstumbler, which only receives access
points that broadcast their SSID, may indicate where an access point is
located at. WPS tells you where YOU are at, based on signals from known
access points.
