[Proj] SPCS NC (3200) -> Lat Long Conversion Problem w/ Program

[Eric Miller]

Double check your input file reading.  It doesn't look too good to me. 
I tried your original code, but hardcoded the sample values you provided
and it produced the desired (presumably correct) result.  All I can
figure is what you're reading into your variables isn't what you think
it is.

BTW, the following might work better for input (though, I'm not sure if
those dummy characters are whitespace).  Or, use fgets() and sscanf(). 
feof() is only true after a failed read and so is useless for seeing if
there is more data available to read.

while(fscanf(ifp, "%lf %lf %lf %lf %lf", &pntX, &pntY, &pntZ, &pntI,
&GPSTime) == 5) {

}

Gerald,

Thanks for the tips.  I will consider libproj4 in the future.

Of interest to the group, I modified my code to use the "pj_inv"
function
instead of "pj_transform" and guess what... the same (incorrect)
output
(posted in original message) is returned by "pj_inv".
