Private Investigator needs GPS mapping software and hardware for laptop

P. S. Having a GPS receiver attached will have no effect on your search results, it will only locate you on the map.

"Accuracy" is a very scarey and misused term when people talk about navigation features.

Location accuracy applies to the GPS and the signals it provides to a program like Streets&Trips. It has absolutely nothing to do with addresses.

The GPS tells the navigation program where it thinks it is on the surface of the planet and the navigation program displays that location on whatever maps it has loaded. That's it.

Addresses are a whole different subject.

The maps contain multiple databases. These databases include regions, like states and provinces, city names, street and road and highway names/numbers and house numbers.

The last one - house numbers - is problematic for map makers and users, too.

The house numbers are normally not placed on the street individually. In most map products the house numbers are allocated in groups which are in turn associated with a particular block on the street. So, in the map database the 500 block of Davis Street might show that the house numbers from 501 to 558 are in that block somewhere.

The map maker now has to guess at a couple of things about how to show where those house numbers are situated. First, they will probably assume that even numbers are on one side of the street and odd numbers are on the other. That's usually a fairly safe assumption. But not always.

Next, they will probably assume that all of the house numbers in the range are used on longer blocks but on shorter blocks perhaps only every second number is used. This one is pretty iffy because it can vary all over the place.

Finally, in order to figure out where to position each house number on the street they will probably assume that each lot is approximately the same width at the street. Again, usually a safe assumption but not always.

So, if you think about those assumptions and compare it to the reality of your lot on your block on your street, you might find it easy to understand how it is that your house is not in the same place on the planet as Streets&Trips or other map programs think it is.

Keep the distinction between the GPS location and address locations in mind, always.

When you get your GPS and connect it to Streets&Trips, when you go out in the yard and fire things up you will see your location plotted fairly accurately on the map display.

But when you search for your house address it's still not going to change where Streets&Trips thinks it is. That has nothing to do with the GPS location plotting.

I hear you loud and clear "Ken in Regina", thanks.

You guys are great. I have more.

First, I really like the look and feel. But.....

In using the free trial with no receiver yet, and I find I do not like the voice guide distance to next turn method. It says "@" 3.5 miles turn left on so-and-so St. Instead of what any GPS program I have ever used does by saying (and my preferred method) "In" 2.0 miles left on so-and-so St.
Is this because I have no receiver connected or can it be changed in the menus?
I do not like having to keep track of how many miles have went under the vehicle but rather know how many miles I have to go before the next turn.

I notice the navigation pane only has the turn arrow and directions text. Will adding an active USB receiver add the other data into the pane as in ETA and such?

Also, Let me be stupid here.

I have a Garmin 60CSx that will allow for a MCX external antenna and a USB connection. Can I use this for my receiver?

Yes, no GPS.

No ETA, some "such."

Yes. You don't need the external antenna unless you are having reception problems with the 60CSx by itself.

Streets&Trips will not see a direct USB-connected GPS signal so you will need to add something to create a COM port for Streets&Trips to use. Those who are doing this use a shareware program called GPSGate. Or you can download a free program from Garmin called Spanner and see if it will work for you.

(Does anyone know if the latest version of Xport will find a USB receiver yet?)

Either way, you can test it with the trial version of Streets to see how you like it with a receiver.
