Hello George,

Have a look at

http://www.dmap.co.uk/ll2tm.htm

and

http://www.posc.org/Epicentre.2_2/DataModel/ExamplesofUsage/eu_cs34.html


The first link points to a web site that performs the conversion on line. It
contains a reference to the second site, which provides the formulae for all kinds
of map transformations, if you want to program them yourself. You can use the first
site to test and debug your program by cross checking the outputs.

By the way, I missed your inquiry when you originally made it, because it was buried
in a thread about Lewis and Clark and River Navigation. It came up only by accident
when I searched recent messages in my in-box for the term "Microsoft"! May I humbly
suggest that we follow a recent suggestion of list member Ken Gebhart to give our
messages more telling subject titles?

Best regards

Herbert Prinz
