After some initial confusion as to what exactly it was that MapInfo had decided to do with Google Earth, the matter has been cleared up with a search for “KML” on MapInfo’s site, which yielded these results:
A Product guide for the MapInfo Link Utility for Google Earth.
Release notes for the Link Utility.
Basically, it lets you export existing MapInfo maps as KML/KMZ for viewing in Google Earth. No biggie, really. It’s sort of expected that self-respecting GIS companies do KML these days:-) (Moshe Binyamin from MapInfo comments on All Points Blog that the utility will probably be released on November 11.)
