NAME

       nad2bin - convert nad ASCII files into binary format usable by nad2nad

DESCRIPTION

       This  command  is  undocumented  upstream.   This  very rough documentation was quickly assembled by your
       friendly Debian maintainer (who doesn't use this command, and so is not the best person to document it!).

       The proj package includes the nad2nad binary, the North American Datum conversion filter used to  convert
       data  between  North  America  Datum  1927 (NAD27) and North American Datum 1983, and cs2cs a binary that
       performs transformation between the source and destination cartographic coordinate system  on  a  set  of
       input  points.   The  coordinate  system  transformation  can  include  translation between projected and
       geographic coordinates as well as the application of datum shifts.

       See the nad2nad(1) and cs2cs(1) man pages for more information.

       nad2nad and cs2cs need arch-dependent conversion data files  in  a  library  directory,  /usr/share/proj/
       Those  files are included in the proj Debian package since 4.6.1-5.  To produce/update them yourself, get
       the *.lla files from

       http://download.osgeo.org/proj/proj-datumgrid-1.5.zip

       and then run nad2bin to produce the binary files used by nad2nad and cs2cs like so:

       # nad2bin < conus.lla /usr/share/proj/conus

       Test nad2nad with the following example:

       $ nad2nad -i 83 -o 27 -r conus << EOF

       71d14'58.27"W   44d20'15.227"N

       EOF

       It should produce:

       71d15'W 44d20'15"N
