North American Datum (NAD) conversion between the NAD coordinate systems—NAD27, NAD83 (1986), NAD83 (High Accuracy Reference Network), NAD83 (2007), and NAD83 (2011)—can be accomplished using two major transformation programs, North American Datum Conversion Utility (NADCON) and GEOCON, created and maintained by National Geodetic Survey in National Oceanic and Atmospheric Administration. Coordinate transformations in NADCON and GEOCON utilize transformational grids, which contain latitudinal and longitudinal shifts between the coordinate systems. Understanding of the grids will provide a full understanding of transformation process and all the numerical results that NADCON/GEOCON provides. In this study, we illustrate how these grids are read, interpolated, and, finally, used to extract shifts through different interpolation methods and other auxiliary information in NADCON/GEOCON.
