-------------------------------------------+--------------------------------
Reporter: voncasec | Owner: grass-dev@…
Type: defect | Status: new
Priority: critical | Milestone: 6.4.3
Component: Projections/Datums | Version: unspecified
Keywords: proj4, location wizard, wxgui | Platform: Linux
Cpu: x86-64 |
-------------------------------------------+--------------------------------
Comment(by hamish):
current situation of loc wiz + datum transform options in devbr6 nightly
wingrass build: (which uses proj4 4.8.0)
test 1: datum transform selection
proj: nzmg, datum: nzgd49, (epsg: 27200)
datum transform: "2" NTv2 grid file
- setup by terms: works!
- setup by epsg code: grid file selected but +towgs84= 7-term in Summary
page & loc'n.
- setup by proj terms: "+proj=nzmg +datum=nzgd49"; grid file selected but
no sign of it in the Summary page and loc'n created with the +towgs84
7-term transform.
test 2: no datum
- setup by terms: proj -> ll, ellipsoid only -> sphere -> error. (see
trac #1967)
these two things are the last majors blocking release AFAICT.
