FX-Collaborate (FXC) is an exploratory development project started in 1998 to study architectural issues involved in implementing collaboration and distributed databases. The approach has been to develop an operational prototype system that would assist us in exploring these issues while simultaneously collecting information from users about what constitutes an effective collaborative system.
Features - FXC emulates many capabilities of the National Weather Service's (NWS) Advanced Weather Interactive Processing System (AWIPS) while allowing remote users to automatically synchronize their displays for collaboration. In addition, FXC includes interactive capabilities such as drawing/annotation tools and a chatroom, and allows sharing of local information between sites.
Architecture -The system was initially developed using Java's Remote Method Invocation and was later changed to use socket-to-socket ip communications as firewall restrictions increased. The FXC system consists of one or more clients and servers. The server is designed to access the real-time database and send metafiles to the client(s) for display and manipulation. The architecture is very flexible and allows the client and server to reside on the same machine and act as a single application, or have clients connect to remote servers.
Applications - The list of possible applications of FXC includes weather forecast/hazard coordination, classroom training, weather briefings to local agencies, and manual forecast product generation.
o FXC has been installed at the Alaskan Aviation Weather Unit, CWSU, and Volcanic Ash Observatory in Anchorage, Alaska to evaluate its utility for volcanic ash coordination. The code has been extended to allow users to initiatalize and run a dispersion model and then display the output of the dispersion model on FXC. The sample image depicts the 500mb winds from the AVN Global model with the Puff-UAF dispersion model output as a multi-colored overlay (courtesy of GSD/AB).
o The Department of Homeland Security is evaluating FXC for alerting the public to the release and spread of a potentially health or life-threatening gas. Through this Geo-Targeted Alerting System (GTAS) application, FXC is able to run the Hysplit model, identify the hazardous areas (call-out area), and transfer that information to a reverse 911 vendor to initiate calls.
o Many NWS offices are using FXC to create web graphics, such as Hazardous Weather Outlook or up-to-the-minute nowcasts. The image below is a sample screenshot using FXC's ability to capture the screen and transfer it to a Web server. This sample image is changed frequently to illustrate specific FXC features. FXC makes it extremely easy to capture real-time data from the AWIPS database, annotate it, and post it to the Web.
Hardware - The FXC server must reside on a linux machine that has the AWIPS software installed on it. The FXC client software has been tested on Windows XP and Linux machines. The minimum suggested client hardware configuration consists of 1GB of RAM and a 1GHz CPU.
