:: About :: Summary ::

Notam Map is a stand-alone Java application written by Andrew Hall and distributed using the Java Web Start launch mechanism.

Preflight Information Bulletins published by the NATS Aeronautical Information Service are available free to any registered user via their web site at http://www.ais.org.uk and Notam Map obtains this data by emulating a simple browser and allowing a user to log in using their own account.

Once the data is downloaded it can be filtered to remove irrelevant items from the data set and presented in alternative views. In addition to a view that presents the text exactly as published by NATS, there is a tabular view that allows sorting on any parameter and a graphical view where individual items are plotted on a map of the UK.

The application maintains a single configuration file notam-map.cfg in the user's home directory and also allows the user to save and retrieve data files to and from the local disk but otherwise no connections are made or data files accessed.

:: Known Bugs ::

The most notable issue hanging over this application is the fact that it relies on the text in the free text field of the notam to conform to a certain syntax in order to identify positions and affected areas. It works for the most part because the text is generally written to conform to a loose syntax but it is not perfect. The data is entered by hand and can therefore contain errors and in any case the syntax itself is sometimes ambiguous. To try and resolve these problems the author is currently working with AIS to tighten up the syntax and to provide them with a means of automatic checking when the data is entered and before it is published.

:: Apologies ::

To the Irish. For some reason the map I obtained did not include the coast of Ireland and so the island appears to have either sunk or been cast adrift.
