GPS Road mapping car?

years ago (& probably now) Telecom now Telstra had vehicles survey mobile network signal strength / quality in new areas and in areas where problems were reported or being fixed. Maybe it was something like that. I guess other network providers do similar these days.

1) Basically, to get a map of te road networkin this country costs a motza, not to mention an accurrate one, so if you run a fleet of vehicles, fitting them with something to gps track where they have been allows you to graduallybuiild up your own map for your purposes and for resale.

It would just occassionally require a vehicle to drive down uncommonly travelled streets to add them to the map.

2) As already sugested, telephone, wireless or satellite coverage testing.

...piles of other TFB and similar ideas....

Now the conspiracy theories start. Was it or wasn't it, did it, or didn't it. Blah,blah,blah

You're probably under surveillance by the FBI. Were they wearing dark suits?

I don't recall, all I remember was this red flash... :->

It's a tad more than 110 miles from Chicago! And I certainly would have known that car if I saw it:

3) Mobile, differential GPS base station. The GPS antenna records the signal, averages it and rebroadcasts a differential signal to someome wanting a more accurate position at their gps device.

Nah! I'll bet that picture was taken in CA or FL. I'll put my money on CA.

Looks like one of the Universal Studios theme parks.

Sounds like a google street view car to me.

Actually, on second thought you might be right. The 1m high pole on top with a small enclosure might just be it. I just wish I'd got a better look at what was on the top of the pole rather than staring at the GPS antenna on the roof.

This is the mob that makes the street view cam:

Here is the US car:

and

The pole on top of the car I saw was taller than that one in the photo, and it wasn't a tripod like bottom.

My street was conveniently missed out on in the major street view mapping just released, as were many other in my surrounding streets, so they could be "filling in the holes".

Dave.

suppose your city has a fleet of 30 rubbish trucks, fit such a device to one and with careful rostering you'll have a map of the city in 30 weeks.

add a load cell & data logger you could map who recycles the most etc!

They only pick up your trash every 30 weeks? How about areas with no trash to pick up, like large industrial areas?

In a "Civic" ?

err, there are none. Most have offices and office, lunch room, etc trash, not to mention industrial "waste" that may or may otbe recyclable.

here (and everwhere else I've lived) it's weekly. If there's 30 trucks there's no more than 30 routes done each day. if there's only one truck with mapping equipment then then it'll take

30 mondays to cover all the monday routes.

Hmm, maybe do the street sweeper instead :)
