NADCON 5 nadcon5.*.b grid files

Support is included for the NADCON 5 nadcon5.*.b grid files. These grid-shift files are provided in the $PCIHOME/etc/grid directory.

NADCON 5 grid-shift transformations are performed based on the shift values in the nadcon5.*.b grid files. Each transformation has two or three corresponding grid files. If a third file is specified, it is used for a height transformation. For example, for D615, there are three grid files; nadcon5.nad83_2007.nad83_2011.conus.lon.trn.20160901.b is used for longitude transformation, nadcon5.nad83_2007.nad83_2011.conus.lat.trn.20160901.b is used for latitude transformation and nadcon5.nad83_2007.nad83_2011.conus.eht.trn.20160901.b is used for height transformation.

Datum-definition file

The datum.txt file contains the PCI datum codes defined for the grid-shift files, as follows:
