Finding coordinates on a map

Jeffrey Kaplan

At poi-factory.com I found a couple of POIs for tollbooths in NH. I'd
like to add POIs for tolls in the rest of New England and New York.
Since I can't find any others, I'd like to build my own.

I know I can browse the map on my Garmin c330, save the location to my
favorites, download to my desktop with g7towin and create a custom POI
file to upload back, but browsing the map on the GPS like that is not
the easiest thing to do, when you only know the approximate location.

So what I +want+ to do is locate the tolls via something like Google
Maps, Mapquest, Yahoo Maps, etc, and extract the lat/long coordinates
that way. But I have not (yet) found a way to get the coordinates from
map browsing. Does anyone know how I can do that?

I'm quite sure that Google Earth displays the coordinates somewhere on
the screen.

Another way would be to create the waypoints in Google Earth, save
them as KML and use GPS Babel to convert them to a POI format.

mapper.acme.com can do that and much more.

That'll work, I'll check it out.

I think it would just be easier to copy the lat/long myself.

Use Google Earth. Read the lat & long of the cursor from the screen.

Use Google Maps. Move the map until the location is in the centre of the
display. Use right-click or any other menu to copy the URL of the 'link'
link which is a permanent link to that location and zoom factor. Then
examine the URL you just copied and you'll see the lat & long in there.

Unless right-clicking selects the exact spot I'm clicking on rather
than just what's displayed, that's not accurate enough.

Someone suggested mapper.acme.com. That one works perfectly, and
allows me to copy/paste the lat/long.
