Supported platforms

The map is available in two forms. The fully interactive (dynamic HTML) version is served to supported browsers (currently Windows versions of Microsoft Internet Explorer 4+ and Mozilla 5+). All other browsers receive a basic version of the map, ensuring compatibility with the maximum number of users' equipment.

Software

The interactive map has been developed using perl 5 (for server-side programming), javascript (for client-side programming, compressed to reduce download times) and mySQL (chosen for its fast database access).

The map images are created on demand by GD.pm, a port of Thomas Boutell's brilliant gd graphics library libgd. GD.pm interface is copyright 1995-1999, Lincoln D. Stein.
