Travis,
I think MapServer is just going to lookup 2958 in the PROJ.4 epsg init
file. So it may well be sufficient to update the entry to refer to the
grid shift file.
Something like changing this:
# NAD83(CSRS) / UTM zone 17N
<2958> +proj=utm +zone=17 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=
I have issue with my WMS service when using a source raster layer that is
in EPSG:2958 - NAD83(CSRS) / UTM zone 17N srs. The issue is that Mapserrver
(proj) does not apply a gridshift when requesting the layer in a different
projection - UTM z17n NAD83. I have a gridshift file for this
transformat
