#631 closed patch (fixed)

Update NZ projections for grid transformation support

Reported by: jpalmer Owned by: pramsey
Priority: medium Milestone: PostGIS 1.5.3
Component: postgis Version: master
Keywords: proj4, NZGD2000, NZGD49, grid Cc:


This patch modifies the spatial_ref_sys table proj4 parameters so the NZGD49←>NZGD2000 transformation grid is used. Also in the case when the grid is not found the lower accuracy 7 parameter transformation is used.

See for more information on the NZ transformations.

Is there a reason we are not applying this patch. I'm tempted to before 1.5.3 release?
