Trying to convert a spreadsheet of Google Earth WGS84 Lat/Longs to NAD27 (Texas). When I do so in CoordTrans, I'm getting two different outcomes when I do a single point conversion vs a batch conversion. See example below.
WGS84 32.48815, -99.76981
Single Point Conversion to NAD27 (Texas): 32.48803, -99.76944
Batch Conversion of same WGS84 point above to NAD27 (Texas): 32.48952, 99.77002 (dropping negative sign in the conversion for some reason...)
Can someone help me figure out why I am getting two different conversions for the same WGS84 point?
