#997 closed defect (fixed)

g.proj returns wrong datumtrans

Reported by: martinl Owned by: grass-dev@…
Priority: blocker Milestone: 6.4.0
Component: Projections/Datums Version: svn-releasebranch64
Keywords: g.proj, datums Cc:
CPU: Unspecified Platform: Unspecified


g.proj behaves strangely when printing datum transform paramaters. E.g.

g.proj epsg=3004 datumtrans=-1

nothing is printed out even epgs code is given.

Setting datumtrans also doesn't work, e.g.

g.proj epsg=3004 datumtrans=1 -j

same with

g.proj epsg=3004 datumtrans=2 -j

Everything is working with -t flag, e.g.

g.proj epsg=3004 datumtrans=-1 -t
Used in whole rome40 region
Default 3-Parameter Transformation (May not be optimum for older datums; use this only if no more appropriate options are available.)

In RC5 everything works well, i.e. without -t. What is purpose of this flag? Thanks, Martin
