Recently I've been designing maps without navigation tools like the Zoom In/Out and Pan tools, or arrows to pan north, pan west, etc.
Instead, most modern mapping APIs support the direct use of the map itself to handle navigation - drag the map to pan, double-click to zoom in, scroll the mouse wheel, shift-drag to zoom, etc.
Is there a set of standard accessibility guidelines for online maps?
Are there valid reasons for needing a "click to pan" control, or any of the other old-school navigation controls? For example, are they used by screen readers or other accessibility aids?
I note that Google Maps has a Pan control, even though it's not strictly necessary.
