"The Precision Information Environment (PIE) Activity Awareness Environment was designed to improve the information synthesis process by bringing in multiple, disparate data feeds and sources, extracting features of interest and visualizing the information to give emergency response professionals insight and situational understanding in a timely and intuitive manner. The system also applies a user recommendation system to help filter the data based on the needs and activities of the user thereby giving them the right information at the right time. http://precisioninformation.org"
