easting northing to long lat

Tue Mar 17, 2009 4:25 pm

I've been using CoordTrans for many years to convert coordinates between NAD27 and NAD83 datums without problems. I recently tried to convert some NAD83 coordinates to Longitude/Latitude and discovered a discrepancy in CoordTrans calculated Lat/Long.

I start with NAD83 E/N 1094940,792440 in New York West NAD83 and the conversion produces -78.7801695,42.1748747 (Datum NAD83). The physical address of this location, when referenced through Google Maps is -77.491774, 43.000488.
Wondering what I'm doing wrong.

Now do I feel stupid...I have coordinates and DATUMS reversed. Works as expected.
Sorry.
