In reference to the question on the lawsuit - from Wikipedia - article "Geocaching":
In the United States, where most geocaching services are hosted, coordinates are not protected by copyright but cache data are. Some commercial web sites listing geocache data are generally protective of their data. People scraping data from geocaching.com have been threatened with lawsuits by Groundspeak, Inc., owners of the site. In 2001, Ed Hall was threatened with a lawsuit. According to Hall, the threat was because Groundspeak requested that he provide a copyright notice on his website, Buxley's Geocaching Waypoint, attributing Groundspeak as the owner of the cache data. However, Groundspeak claims the dispute occurred after Hall refused to remove a cache listing from his maps at the request of a cache owner. As a result, his site now acknowledges the various sources of cache data he uses, but after a disagreement with Groundspeak, Inc. about licensing, he no longer includes any data from geocaching.com. Navicache.com (and others) take a more 'open-caching' type approach, sharing their database with Buxley's and others.
