I have an quite big CSv File I want to have in Google Maps or just on a map. These are just coordinates but I have 600.000 of them..
Do you have any Idea how I can do t
The easiest way to do this is generate a KML file (see http://code.google.com/apis/kml/articles/csvtokml.html for a possible solution). You can then open that up in Google Maps by storing it online and linking to it from Google Maps as described at http://code.google.com/apis/kml/documentation/whatiskml.html
EDIT: http://www.gpsbabel.org/ may let you do it without coding.
