Lat and Lon for specific locations

 

Where do I find Lat and Lon information for specific locations? I've seen the answer to my question someplace here at this web site but can't find it now. Perhaps the answer deserves a place in the FAQ section.

Thanks

My personal favorite is

My personal favorite is Microsoft Streets and Trips 2007. However, check out this link bud.

Lat and Long

I use google earth. This is a free program from google

.

MapSource

GPS Visualizer

Also, take a look at the FAQ page linked at the top of each page.

Why don't we just ask the GPSr?

This may be model dependent but on my nuvi 650 here is what I do.

- Turn GPS antenna off.
- Use the "Where to?" function to set any point on the GPSr map. This will come in handy later. Example: "Where to?" -> "Food, Lodging" -> "Food" -> "Mexican" -> scroll down and select any item. Then press "Show Map" -> "Set Loc."
- Return to the main menu and follow these steps: "Where to?" -> "Coordinates"

The screen will show the exact lat/long in the format needed for POI files.

This will work fine for a few locations. I use this method to fix errors in my POI files. If you are creating a big POI file, then the other programs listed on this thread work swell.

GPS visualizer ( http://www.gpsvisualizer.com/geocode ) works great with one or LOTS of locations. That's how I build the large POI files.

FWIW

you are right.....model dependent

choices are wide as to which you will choose
for some you may pay and some are no cost
remember this and you'll never lose
accuracy is a must or else you'll be lost

This sounds great, however the C330 doesn't show coordinates as newer models do.

DKTGPS uses a C330.

Map APIs

If you can write a program, you can call Google Map and/or Yahoo Map APIs. I find that Google Map API seems go give you coordinates that are closer to MapSource values (hence more accurate when using Garmin GPSr).

I used

I used terraserver.microsoft.com. It gives lat/long out to 5 decimal places. Unfortunately, it's not as friendly as google maps. So, I'd typically look up an address with terraserver, and if there was confusion, bring up google maps, throw it on hybrid, and then compare the two maps, zoom in and get the coordinates.
