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
