I use GPS Status - it's a great little free app.
I use this as well. Great app but unless I missed something it doesn't have a "mapping" feature?
I concur that either Google Maps or Google Earth should offer what the OP is wanting. Just need to figure out how to enter those coord's and insure that you are using the proper format for Lat & Long.
but how do you get the gps longitude and latitude of your current location on the android in google maps ?
