SEASR's Location Entities To Google Map is a tool for extracting locations from a text that can be displayed on a map. It uses OpenNLP to extract the entities, and then displays both the sentences and the locations in Google Maps.
The page for this tool on SEASR's website is no longer active. However, it can still be viewed via the Internet Archive.
