Hello.

Those of us who work with geographic information --and hope to view our maps
in SVG-- would like to suggest explicit treatment of real-world coords,
within chapter 8 of the working draft. We'd like to see the ability to
transform outside the CSS realm (points, mm, inches) to metres, kilometres
etc. This allows users to do things like measure real-world distances
on-screen (for example, click on origin and destination on a SVG map, and
get the crow's-flight distance), calculate polygon areas...

Maybe real-world coords, units etc. are in there somewhere, but it's not
obvious reading over the current SVG draft.

By the way, my colleague has had a VML-format map server up for over a month
now:

Cheers,
Mike
