The PA Wind Map uses a simple set of controls to manipulate
the information on the map. The HTML Viewer interface
used on this web site consists of a map display area,
title, toolbar, layer list, scale bar, North arrow,
and overview map. Below is a table containing each of
the tools, their names and their meanings.
