Earlier this Last year, in June, Don Meltz wrote an interesting blog “ArcGIS vs QGIS Clipping Contest Rematch” where he let compete ArcGIS and Quantum GIS in a clipping contest. The benchmark contest data set in question is a 878MB ZIP file (ContourClipTest.zip). The blog page gained a lot of comments, even from ESRI since some ArcGIS versions crashed on this test data set.
Find below the various timings compiled from the blog and the comments:
1) Proprietary software
|ArcGIS 9.3||crash after 1h 9min: ERROR 999999: Error executing function. Invalid Topology [4gb file limit.] Failed to execute (Clip)||unknown|
|ArcGIS 10.0||crash likewise||unknown|
|ArcGIS 10.1||ESRI promise to calculate it in 34 seconds in this updated version (did anyone test?)||unknown|
|GlobalMapper (version?)||30 mins||unknown|
|GlobalMapper v11.02||49 sec||Windows XP w/ 3.5GB RAM|
|Manifold 8 (64bit)||31 min||Windows XP64 16 gb. RAM and 2.33 GHz|
Note: The two GlobalMapper results are a bit funny, perhaps always minutes?
2) Free and Open Source Software
|Quantum GIS (version?; Simple features)||4-5 min||unknown|
|GRASS GIS 7 (topological GIS)||5 min||Dell PowerEdge 2950 from 2008, Intel Xeon 2.66GHz, 8GB RAM|
|gvSIG||to be done|
|PostGIS||to be done|
Notes: Hope volunteers will test this also on gvSIG and PostGIS (and other FOSSGIS)! Please report…
