PyGRASS: Use GEOS buffering
| Reported by: | sbl | Owned by: | |
|---|---|---|---|
| Priority: | normal | Milestone: | 7.6.2 |
| Component: | PyGRASS | Version: | svn-trunk |
| Keywords: | buffer | Cc: | |
| CPU: | All | Platform: | All |
Description
Currently, PyGRASS uses native buffering functions (Vect_area_buffer2): https://trac.osgeo.org/grass/browser/grass/trunk/lib/python/pygrass/vector/geometry.py#L1654 This is known to have issues, which are not planned to be fixed (see: #3448).
Thus PyGRASS should use GEOS-based buffering (as in v.buffer): https://trac.osgeo.org/grass/browser/grass/trunk/vector/v.buffer/main.c#L564
