I just downloaded proj.4.4.6 as a windows prebuilt executable, which
appears to be slightly older than the source code version 4.7.0.
I'm experiencing similar problems as described in
Using a cs2cs command line like
> cs2cs +proj=latlong +ellps=clrk66 +nadgrids=ntv2_0.gsb +to
+proj=latlong +ellps=GRS80 +datum=NAD83
(with the ntv2_0.gsb properly installed and all environment variables
set, including debug) the first coordinates I enter (or just pressing
enter with no input) result in the message
* * 0.000
and the next coordinates I enter give wrong results or zeroes.
Trying other NTv2 grids led me to believe that they are just ignored:
the resulting coordinates do not change when I - for example - enter a
wrong filename for the +nadgrids option. In that case, I get an error
I suspect this all is because the windows version of PROJ.4 is a bit
old. Since I have no knowledge or tools to build it myself, is there a
place where newer versions of PROJ.4 are available as an executable
Any suggestions or other causes for this problem would also be
Thanks in advance
