[postgis-users] Fwd: Location of nadgrid file

[Jan Hartmann]

Or perhaps the place in the source code that generates the error message:

ERROR:  transform: couldn't project point (155000 463000 0): failed to 
load datum shift file (-38)

I did several greps on the postgis-2.1.0SVN tree, without any result

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?

Jan
