CAVE Annotation Tool (CAT) is a graphic annotation capability designed for AWIPS II. It provides a wide range of annotation capabilities for creating web graphics and presentation material. It has many of the graphic capabilities of PowerPoint™ and additional capabilities such as the creation of animated graphics (gif) and the export of KMZ (Google Earth) display files.
Its unique strength is its integration with AWIPS II. This allows forecasters to display the desired data on their workstation and quickly annotate the displays. The AWIPS "bundles" can be used to call up the desired combination of weather products with a single menu selection. All of the AWIPS graphic manipulation features are available to the forecaster. After the graphic is created, a single menu selection can send the graphic to the desired web site.
CAT also supports the creation of animated images. A forecaster can annotate a series of graphic frames with such information as the movement of a storm or front and capture that directly in a gif image. The speed of animation can be adjusted so that the user can dwell on each frame for several seconds.
Unfortunately, the restrictions on the AWIPS network makes it difficult to access external web sites for supplemental weather data. Thus, if a forecaster depends heavily on graphics created outside of AWIPS then the graphic products may be more efficiently created outside of AWIPS.
Leveraging FXC - The Forecaster's Experimetal Collaboration (FXC) tool was used widely by NWS forecasters for over a decade. FXC contained three major components: graphic annotation, real-time collaboration, and AWIPS weather data display and manipulation.
The graphic annotation was used heavily by the NWS Southern and Central regions to create their daily, or more frequent, graphicast products. CAT retains all of the drawing capailities in FXC and includes many additional features requested by users. Although some new pop-up menus and other slight menu changes exist in CAT, the user interface remains basically the same, making it easy for the forecaster to transition to CAT.
The collaboration capability has been integrated into the AWIPS II baseline. It allows forecasters in different offices to collaborate in real time with each other using graphic displays and text. The 12Planet messaging functionality has been integrated into AWIPS II and is expected to replace the 12Planet software once all offices have the new AWIPS II system installed. Since collaboration is fully integrated into AWIPS II, CAT does not provide a collaboration capability.
The graphic display and manipulation capabilities are provided by AWIPS II. AWIPS II has access to a large diverse set of real-time data that it can display in a variety of different ways. Since CAT is basically an additional workstation function, CAT takes full advantage of this AWIPS II capability.
CAT Architecture - The CAT software is an AWIPS II plugin written in Java that can easily be installed om AWIPS II. The plugin utilizes the AWIPS II core functionality and behaves very similar to all other AWIPS II plug-ins. It is different in that the user installs it and the code is not maintained by the AWIPS II contractor, but rather by GSD.
FXC is a stand-alone program that uses the AWIPS I software to access the AWIPS I data base and to create graphic meta-files. The graphic meta-files are then rendered into a separate dedicated FXC window.
