<DIV><FONT size=2>Frank (and others),</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2> I've noticed that Proj4 seems to do NAD 27 / 84
datum</FONT></DIV>
<DIV><FONT size=2>conversions, but I'm still a little lost on how to
specify</FONT></DIV>
<DIV><FONT size=2>the parameters on the command line, or drive Proj4
using</FONT></DIV>
<DIV><FONT size=2>the function calls to do the datum
conversion.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2> I've looked thru the Proj4 doc and the ShapeLib
contrib </FONT></DIV>
<DIV><FONT size=2>doc at the info there is on using Proj4 to do datum
conversion.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2> Is there any additional datum conversion info
specific to Proj4?</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Thanks!</FONT></DIV>
