------------------------------------------------------------+---------------
Reporter: dido | Owner: grass-dev@…
Type: defect | Status: new
Priority: major | Milestone: 6.4.5
Component: Vector | Version: 6.4.4
Keywords: Polygons disappear v.generalize simplification | Platform: MSWindows 7
Cpu: x86-64 |

Polygons disappear after v.generalize simplification.
A large rectangular polygon dataset is used with ~14 000 features.
Polygons are first processed with rmarea to remove all polygons of size
900 m2. Then a simplification is executed with v.generalize using a factor
of 10, all other parameters defaulted.
After simplification several large polygons are missing from the set
rendering it useless.
System is a win7x64; QGIS 2.6.1 and GRASS 6.4.4
Dataset can be provided upon request (being a 7.5mb shapefile).
