What it is
Coordinate Helper is a utility that allows you to convert coordinates, plan and declare routes. It will also import Google Earth kml placemarks (waypoints) for easy selection. You can copy the resulting information and view the route using Google Maps. It can also generate "dummy" igc file which can be useful for scoring in friendly competitions.
