#1527: vector projection over wrapping boundary is split
----------------------+-----------------------------------------------------
Reporter: pertusus | Owner: grass-dev@…
Type: defect | Status: new
Priority: normal | Milestone: 7.0.0
Component: Vector | Version: svn-trunk
Keywords: | Platform: Linux
Cpu: x86-64 |

Comment(by mmetz):
Please try attached patch for v.proj. The bug is in the proj4 library
which automatically wraps to -180 - 180 if the output location is latlon.
This does not work with topological vectors and causes the observed error
messages. The attached patch tries to automatically figure out if wrapping
coordinates to the range 0-360 is needed and wraps if needed (should be
made a user option I guess). BTW, this bug appears also in GRASS 6.4, only
that 6.4 does less thorough topological error checking.
