<DIV><FONT face=Arial size=2>Can I please ask <SPAN

<DIV> </DIV>
<DIV><FONT face=Arial size=2>In an attempt to convert some data from projected
to lat/lon, I'm attempting to use cs2cs.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>The data:<BR>My coordinates of 2174727 164482 are
based on NAD27 3104 (Long Island).<BR>My lat/lon of -73.370096 40.675382 is
based on a geocoding calculation from a Sagent geocoding engine.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>I'm attempting to use cs2cs to calculate lat/lon
values for a rather large file.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>In testing, I use the command:<BR>echo 2174727
164482 nad27:3104 |c:\ms4w\proj\bin\cs2cs -E -f
%3.6f +init=nad27:3104 +to +proj=latlong +datum=NAD83</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>This returns coordinates of -55.478096 40.211109...
somewhere out in the Atlantic Ocean. </FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>I've tried a brute force approach against all the
NAD27, NAD83 and EPSG definitions but cannot come up with anything close to the
lat/lon I expect.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>I've been told that the coordinates I'm using are
actual and not "padded" for any reason.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>If anyone has any insight as to how I could resolve
this issue, I'd be most appreciative.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>Thank you</FONT></DIV>
