I need to produce NADCON grid from our NTV2 grid.
I have searched the web for NADCON grids specs and only found that a NADCON
grid is a bundle including the data AND the software that reads them ... I,
also, found that there are two files needed (one for longitudes, another one
for latitudes) and that longitudes/latitudes must be round even values ...
But, I am not sure of all of that.
On the other hand, PROJ.4 includes a reader for converting lla (ascii) to
binary ... and lla is mentioned in some web pages.
So, is there "real" specifications for NADCON Grids ? and could someone point
me to them ?
