FYI the solution was fixing the geotransform in the geotiff. The geotiff specification defines a PixelIsArea-style geotiff as having coordinates for the upper-left corner of the pixel. I was using the center of the pixel as is normal for scientific imagery data. I still need to verify how SIFT is doing it, but will like wait until after we move away from geotiffs as the default since all geotiffs will need to be regenerated.

Jay Cable at GINA brought up a possible issue with Polar2Grid where a half pixel shift can be seen when viewing produced geotiffs in QGIS. My guess is that QGIS isn't properly respecting the "pixel is an area" nature of most geotiffs. We should make sure I'm not doing the same in SIFT.
