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=-5000→ 12sec - ArcGIS 10.2:
Buffer StatPolygon Stat_5000 "-5000 Meters" FULL ROUND NONE→ 6min 50sec
- GRASS 7:
