The Challenge !   Supporting a wide range of partners, including military, inter- agency, national partners, & NGOs !   Common situational awareness is needed by all partners !   Responding organizations both need, & can provide a great deal of information !   Partners are distributed & sometimes disconnected !   Partners should have direct access to the technology itself The goal is to deliver dynamic, collaborative maps
