To give you an idea of the range of ENCs which are produced or are in production worldwide, we have provided below an easy to use graphical catalogue which was revised in August 2007 to simplify the display options and provide additional functionlity (in the application, click Ctrl - F5 to ensure you are viewing the latest version).
Use the layers along the top right to control the information on display. The usage band mode allows you to view actual data coverage details, and to filter your display to show only those ENCs of the navigational purpose you are interested in. The simple mode shows just cell limit information for the remaining ENCs which are available (shown in red) for which we do not have data coverage information, as well as ENCs which we believe are being produced (shown in blue).
Use the buttons along the top left to zoom and pan, and to select and query the ENC information on display. Further information on how to get the most from the catalogue, now revised for the latest version, can be found here.
