I am a Mapinfo Professional user and currently I am using MapInfo professional version 15.0 with Discover 17.0. Previously, I cannot figure out how to import Google Earth KML file to Mapinfo. But after upgrading to Mapinfo Professional 15.0 bundled with Discover, I can easily import KML file to Mapinfo.
Here I will show you how to import KML file to Mapinfo Professional.
Open MapInfo and go to Discover | Import and Export | Vector Import. Next select Google KML from the list.
Press OK and browse to the KML file you may have.
Specify the output format, destination and also coordinate system. You may also to transform the coordinate if you want. Then, press Import to start importing.
