<font face="Times New Roman, Times, serif">Can anyone tell me
where the nadgrids-file, as used by proj4 to apply grid shifts
to a projection, should be installed for postgis? I produced
one, put it in the standard proj installation directory
(/usr/share/proj), and it works from the commandline with cs2cs.
However, when I put an entry in the postgis spatial_ref_sys
table for a new projection with this nadgrids file, the
st_transform command says: "failed to load datum shift file
(-38). It also happens when I put in the whole path. What should
I do?<br>
