Sigmet Decode is a new SIGMET viewer, making it quick and simple to view SIGMETs on a beautiful and easy to use interface. SIGMETs are shown worldwide on an innovative split-screen display, allowing a table and map view to be shared simultaneously. Routes with multiple waypoints can be created using a global navigation database and are correctly displayed as great-circles. Any en-route SIGMETs can then be immediately listed and zoomed in on. The future position of moving SIGMETs is visualised using a simple timing slider. The raw text of SIGMETs can be viewed or hidden and the guidelines used to build the SIGMETs (ie N of N25) can also be seen if desired. Please send any questions or comments to [email protected]
