Vector buffer (special case)

Task: Create buffer around vector polygon with negative distance
Input data: Vector layer 'StatPolygon' from ArcCR500 dataset
Comparison: Windows Server Enterprise • Intel Xeon CPU E5520 2.27GHz 2.26GHz (2 processors) • 8GB • 64bit OS
  • GRASS 7: v.buffer input=StatPolygon output=Stat_5000 distance=-500012sec
  • ArcGIS 10.2.0: Buffer StatPolygon Stat_5000 "-5000 Meters" FULL ROUND NONE6min 50sec
Vector buffer with negative distance (GRASS)
