It's an easy, two-step process to convert any shapefile to KML with ExpertGPS Pro. View your GIS layers over Google Earth's color imagery, and create KML files from your shapefiles to share with clients or to publish online.
The first step in converting shapefiles to KML is to Import your Shapefile, using Import on the File menu. ExpertGPS Pro automatically reprojects your shapefile from UTM, state plane coordinates, or any other projection into Google Earth's native format (latitude and longitude in decimal degreees, in WGS84 datum).
To finish the KML conversion of your shapefile, press F7, the View in Google Earth command, and ExpertGPS will convert your GIS data to KML and automatically launch Google Earth to view your KML data. You can also click Export on the File menu to convert your shapefile to KML.
