Sometimes I like to use OpenStreetMap.org online maps; the GPS coordinates search URL for their maps is something like this (quote from their user support website):
Is there something like %Lat% and %Long% (and perhaps %Altitude%) in PWP to access the separate mapping coordinates?http://osm.org/#map='zoomlevel'/'latitude'/'longitude'
Replace the stuff inside the apostrophes with the following:
'zoomlevel' = something between 0 (no zoom) and 19 (highest zoom)
'latitude' = the latitude you want
'longitude' = the longitude you want
