That seems to be a datum error. Make sure you set the good parameters for
datum when using nad83 or nad27.</font><font size=3> </font><font size=2 face="sans-serif"><br>

Hello all-<br>
<br>
I'm trying to figure out how to reproject some points from a UTM projection
to Geographic (WGS84) projection. This works fine when I'm working
in UTM Zone 12 with NAD83. When I try the same code for Zone 11 NAD27,
I get a slight shift in the points (to the east) and an extremely slight
shift up (to the north).<br>
<br>
I've included the following code as it stands now, I've tried all sorts
of things thinking that I need to somehow include more information for
the new spatial reference (the destination SR), and so far I'm coming up
empty...<br>
<br>
Anyone have any ideas what I'm missing?<br>
<br>
Where sSpRefParams is a string that contains the WKT projection information
from a valid layer...<br>
<br>
srOld = new OSGeo.OSR.SpatialReference(sSpRefParams);<br>
<br>
srNew.SetGeogCS("Geographic Coordinate System", OSGeo.OSR.Osr.SRS_DN_WGS84,
OSGeo.OSR.Osr.SRS_DN_WGS84, OSGeo.OSR.Osr.SRS_WGS84_SEMIMAJOR, OSGeo.OSR.Osr.SRS_WGS84_INVFLATTENING,
"Greenwich", 0.0, "degree", 0.0174532925199433);<br>
<br>
ctTransform = new OSGeo.OSR.CoordinateTransformation(srOld, srNew);<br>
<br>
