finding latitude and longitude to add them in picture meta data

My Nikon D70 has not GPS built in. It is very good to add this info as picasa and flickr will automatically show where the picture was taken.

I have found software called GPSPhotoLinker which will add this info to the picture. If you use some GPS software (I know that IGO can save the GPS route) and then you can just import it to this application. Of course it is good if your camera date/time is in sync with your GPS route.

It allows you to add latitude and longitude manually, but problem I have been facing was how to retrieve this info.  I was not able to get it from google maps. I have found this site where you can point to place on the map and it will show you LAT & LOG.
