JavaScript Measure Tool

[Ian Tidy]

Thanks Richard,

I have almost finished building my own based around some of the ideas
from GeoMoose.  I was going well until I tested with IE, which doesn't
support a canvas without help.  I have since found my bugs and fixed
them (thanks to Google excanvas).  All I have left to do is write the
measurements back to the screen.

Thanks for your suggestions.

Cheers Ian

A lot of people approach this with a higher level
library/client/framework like OpenLayers, bBox, MapBuilder.BapBender,
GeoMoose, etc. If you want to build your own, all of those would
obviously have some good example JavaScript.
